Building a public portfolio & LinkedIn
Your seniors hit 5–8 LPA because they had no portfolio. You already think differently. The gap between average and top at BMS isn't talent — it's signals you build now.
Use this chart for context, not as a target to feel. These numbers are 3–7 years out — anchoring on them too hard means Year 2 feels disappointing when it doesn't look like a rocket. The thing you actually control week to week is: did I finish a project, push a repo, learn one new thing. Those process goals are the real plan. The chart is just proof the process leads somewhere real.
| Domain | Type | India demand | Start difficulty |
|---|---|---|---|
| Embedded / IoT ← your path | Both | 🔥 Very high | Medium |
| VLSI / Chip Design | Hardware | 🔥 Very high | Hard |
| Edge AI / TinyML | Both | 🔥 Emerging fast | Hard |
| Communications / 5G | Both | High | Medium–Hard |
| Power Electronics / EVs | Hardware | High & growing | Medium |
| RF & Defense / Aerospace | Hardware | Stable / niche | Hard |
Six different AI models reviewed this roadmap independently — Claude, GLM, Opus, Perplexity, Gemini, ChatGPT. Every single one flagged the same risk: trying to run all 8 tabs at once during this break. So this list is comprehensive on purpose — it's everything you could explore — but it's tiered so you know exactly what to actually do versus what to just be aware of. Don't run "Must Do." Run a few things from it, well.
The actual finish line for this break: by the time Sem 3 starts, you want to be "the person in class who already has a working IoT project on GitHub" — not "the person with a beautiful roadmap." One finished, demoable thing beats four half-finished ones. That's it. That's the whole break.
You're already carrying real social surface area — TEDx, Toastmasters, maybe Rotaract. This isn't more of that. These two are solo, asynchronous, zero scheduling — they fit around everything else instead of competing with it.
In-person IoT meetups and cold-DMing people ahead of you on this path are genuinely useful — but they're Year 2+ moves, once Toastmasters has settled into a rhythm and isn't still being built from scratch. Don't add a fourth social commitment on top of three you're already carrying.
These aren't separate from your technical learning. They're how you make sense of why you're building what you're building.
One cycle per week = 52 micro-projects and a year of consistent GitHub activity by graduation. That history is nearly impossible to fake and impossible to ignore.
Where to buy: Robu.in, Electronicscomp.com, or Quartzcomponents.com — India-based, good quality, fast delivery. Avoid Amazon (overpriced, often fake). SP Road, Bengaluru — excellent if you want to see before buying.
Every project has two layers. The technical layer is what you built. The PM Frame is how you present it in any product or internship interview — same project, completely different signal. Build both habits from project one.
ESP32 + DHT22 + OLED display. Show temperature & humidity on screen. Send data to Adafruit IO or ThingSpeak. Your first end-to-end IoT system — sensor, microcontroller, display, cloud.
ESP32 hosts a web server on your local network. Open a page on your phone and toggle an LED or relay. Teaches HTTP server on a microcontroller. Upgrade: add Telegram bot for remote control from anywhere.
Add cloud logging — every message sent stored in a Google Sheet. Add a Telegram bot showing received messages in real time. Turns existing hardware into a connected IoT system.
ESP32 + relay modules + Node-RED dashboard. Control lights and fan remotely via MQTT. This is literally what Honeywell and Schneider Electric build at enterprise scale.
Vibration + temperature sensors on a motor. Log data to cloud. Use a simple Python ML model to detect anomalies before failure. "Predictive maintenance" — a multi-billion rupee market.
ESP32-CAM detects faces → compares against stored images → marks attendance in Google Sheets. Combines computer vision, embedded hardware, and cloud. Very few undergrads attempt this.
Train a model on Edge Impulse → deploy on Arduino Nano 33 BLE Sense → trigger real actions. "AI running on a ₹2000 chip with no internet" is a conversation-stopper in every interview.
Take your best Year 2 project. Custom PCB via EasyEDA + JLCPCB (~₹500 for 5 boards), 3D-printed enclosure, OTA firmware updates, deployed cloud backend. Not a breadboard. A finished product.
Copy this, customise the bold parts, and send via LinkedIn message or email. Keep it exactly this short — founders don't read long messages from students they don't know.
The "I work for free" line is deliberate — at your stage the internship is the payment, and it removes all risk for the founder. Use it only with tiny startups (under ~15 people, pre-Series A). With funded Series A/B companies that have real intern budgets — including Ather, which is listed as a primary target below — drop that line entirely. It can read as signalling low value instead. For those, just ask for the internship and let your projects speak.
These aren't three equal options. They're a progression. Your primary targets are IoT product companies — the bridge between your embedded skills and your TPM destination. The others open up as your profile grows.
Companies where ECE background + product thinking both matter. You're not just an embedded engineer here — you're someone who can eventually own the product. These are your Year 2–3 targets.
Great for building technical credibility in Year 2. Harder to transition to PM from here, but the engineering depth helps you be a better TPM later.
These are harder to break into from ECE — most candidates are CS students with stronger product portfolios. Don't close the door, but don't make these your primary plan. They become realistic after your IoT product internship + 2–3 strong PM-framed projects.
Timing: Apply for summer internships (May–July) starting in February. Apply for 6-month internships (Sem 7/8) starting 3 months before your availability. Cold outreach to IoT product company founders is 3× more effective than any portal. Use the templates in this tab.
Everyone has ideas. Very few ECE students have a working product with a real enclosure, deployed firmware, and a GitHub repo. Even one properly finished product puts you ahead of 80% of your batch at any college.
Write a Hackster.io project page for every build. Push to GitHub with a proper README while the project is still in progress — not after. This creates a visible track record that builds quietly before you ever send a cold message. You don't have to perform on LinkedIn — your GitHub history and Hackster write-ups do the talking.
Smart India Hackathon, TI Innovation Challenge, IEEE competitions, Bosch Future Mobility. Participation shows initiative on your resume. Winning changes your trajectory. The network you build while competing is often worth more than the prize itself.
Everything you do should create a verifiable signal — proof of capability. Most students produce zero signals beyond a marksheet.
These are semester-time moves — they need other people, a campus, and momentum that a solo break doesn't have. Do these once Sem 3 starts, after the Break Plan tab is done.
At ₹40–80 LPA, nobody looks at CGPA. They look at what you've built that actually works, how you think, and how well you explain your decisions. Your creativity and planning instincts are real assets — they compound on top of technical credibility, not instead of it. You're already thinking the right way. Now build.
If your instinct is "safe option" — GATE as a backup because BMSIT placements look scary — that's the wrong reason. Starting GATE prep in 2nd year trades your highest-leverage years for a credential that doesn't automatically fix the outcome you want.
By then you'll know if your embedded/IoT path has produced internship offers and a strong portfolio. If yes, you don't need GATE. If not, you start 1 year of focused prep for IIT/IISc M.Tech — from a position of knowledge, not fear.
GATE prep at a serious level requires 1–1.5 years of focused study: EMFT, signals, control theory, networks, analog circuits, advanced maths.
If you start this in 2nd year, the opportunity cost is:
— Fewer embedded projects
— Weaker GitHub activity
— Less time for internships and hackathons
— A GATE score but below-average portfolio depth
You'd arrive at M.Tech having traded the exact years when hands-on building is most accessible. And at IIT/IISc, you'd still be competing against people who built things.
You can keep GATE on the table without sacrificing your primary path. Here's how:
Go hard on the embedded + IoT + AI roadmap. Target:
• 8–10 real projects with GitHub repos
• 1–2 solid internships (startup is fine)
• Public LinkedIn + Hackster presence
• At least one competition entry
Subjects that overlap with your path anyway:
• Signals & Systems → aligns with DSP (Sem 4)
• Control Systems → aligns with Circuits & Controls (Sem 4)
• Computer Organization → aligns with ARM (Sem 5)
Study these well for your actual exams. That's your 10% GATE prep.
If and when you go GATE: At that point it's a power move, not a fear move. A strong portfolio + IISc M.Tech label + continued building is an extremely strong combination. IISc themselves say M.Tech grads who do DS/Algo prep and projects land Qualcomm, Cisco, NVIDIA, TI, Amazon. The brand helps open doors — but you still need to walk through them.
This tab is the thread that connects everything in this roadmap. The embedded projects in the Projects tab, the internship companies in the Internship tab, the subjects in the Curriculum tab — this is where they all point and why.
You're not building embedded skills and then later switching to PM. You're building both simultaneously from Year 1. The same project does both jobs when documented right.
Each year has a technical goal (from the other tabs) and a PM goal (from this tab). They're not two separate tracks — they're two sides of the same work.
Technical: ESP32 + sensors. Smart room monitor. Upgrade Morse project. GitHub live. C basics.
PM layer: Write a PM Frame for every project you build. TEDx curation. Toastmasters — treat it as a product you're launching. Use apps critically.
Technical: Home automation + MQTT. Predictive monitoring. Attendance system.
Python — exact resource: Automate the Boring Stuff (free online book), Chapters 1–11. Covers everything you need, no more.
SQL — exact resource: SQLBolt.com — free, interactive, 2–3 hours total. That's the whole skill.
LLM concretely: Follow the OpenAI quickstart guide verbatim. Then build one tiny RAG pipeline — feed it your sensor logs, ask it questions. One project where the LLM is a feature, not just a dev tool.
Cloud concretely: Follow the official FastAPI tutorial (30 minutes). Deploy on Railway or Render (both free). Store sensor data in Supabase (free Postgres). Query with SELECT, WHERE, GROUP BY. That's the entire skill you need at this stage.
PM layer: MUN — compete. One case competition. Cold outreach to IoT product companies begins. Read Inspired by Marty Cagan.
Technical: TinyML project (Edge Impulse). ARM Microcontrollers (Sem 5 — go beyond syllabus). Begin final year product.
PM layer: Internship at an IoT product company (Ather/Bytebeam). Touch real users. Toastmasters producing results.
CAT "quietly" means: 45 min/day on quant from Sem 5 onward — that's it. Verbal is already your strength. Use iQuanta or TIME material. You're not grinding CAT yet, you're just keeping the door open so you're not starting from zero in Year 4 if you want it.
Technical: Full PCB product — final year project. Ship it. OTA updates. Cloud backend. This is your single biggest portfolio piece.
PM layer: Apply to IoT/hardware APM roles. Optionally consumer tech APM. Decide: work 1–2 yrs then IIM, or direct APM. Both paths are open.
Not CRED APM. Not Bosch embedded engineer. Something in between — and more interesting than either.
Why this is more achievable than consumer APM: At Ather or Bytebeam, a candidate with real embedded experience is rare and valued. At CRED, you're competing with 500 CS students who've been doing product teardowns since 2nd year. Start where your background is an unfair advantage.
Right now you're hedging two things at once — deep embedded engineer credibility and TPM/PM/consulting prep. That's fine and cheap in Year 1–2: reading Inspired or The McKinsey Way, writing PM Frames, doing Toastmasters — none of that competes with embedded depth for your time.
But it stops being cheap by Year 3. A summer spent on case competitions instead of a deep IoT internship is not a small trade — it's a real one. You can't do both at full depth in the same window. Without an explicit decision, the risk isn't picking the wrong track — it's drifting into Year 4 with a portfolio that's good at neither.
The checkpoint itself: by end of Sem 5 (around when ARM Microcontrollers wraps up), look honestly at what you have. Is your embedded portfolio stronger, or your leadership/PM portfolio stronger? Which one do you actually want to go deeper on for the Year 3 internship and Year 4 final project? Pick the primary track then — not now, and not by accident. The other track doesn't disappear, it just becomes maintenance instead of primary, same logic as the weekly learning loop.
You don't decide this now. You decide this at end of Year 3 based on what your profile looks like and what feels right. All three use the exact same Year 1–3 foundation.
