who owns outcomes, not just code. Five years in, most recently Head of Engineering at Fhynix.
Nice to meet you
I'm a full-stack engineer based in Chandigarh, India, with 5+ years building products end to end. Most of my recent work is React Native — but the backend is just as real. I care about the systems under the UI, and the cost of running them. Lately that includes AI: RAG pipelines and tool-calling agents in Python.
I tend to own the whole thing. I shipped an Android platform in ~3 weeks against a 3-month vendor quote, took an LLM assistant to production for about $10/month, and designed the recurrence engine the entire product is built on. My arc has been SDE Intern → SDE 1 → SDE 2 → Lead → Head of Engineering — steadily more ownership.
I hold every claim to one standard: would it survive an engineer asking me about it in an interview?
EXPERIENCE
INTERN → HEAD OF ENG
I show up.
Three-plus years on LeetCode without missing a single day — through jobs, side projects, and everything in between. The same habit shows up in the work I ship.
Where I've worked
Head of Engineering
MAR 2025 — AUG 2026- ✶Built an LLM-powered AI assistant from a 2-day MVP to the flagship feature, turning voice, image and text into structured tasks — entirely on the frontend, no AI server — for about $10/month in model costs across hundreds of active users.
- ✶Designed an RRULE-based recurrence engine, replacing per-instance storage of hundreds of rows per recurring task, with a live, backward-compatible migration — the core system every other feature is built on.
- ✶Architected a unified task data layer (windowed store + cache + API, one read/write path) that cut production issues from weekly to monthly.
- ✶Shut down a spam attack that was spiking AWS costs and crashing the service, with rate limiting, request filtering and WAF rules.
- ✶Built reminder workflow automation: WhatsApp reminders and daily summaries on a Bull queue, plus silent-push notification syncing.
- ✶Built a self-managed subscription system on App Store / Play IAP using webhooks and reconciliation polling, with no billing SDK; led a small team with a planning-first culture and strict PR reviews.
Lead Engineer (Contract)
DEC 2023 — MAR 2025- ✶Shipped the app's entire Android platform — the app was iOS-only — in ~3 weeks of core work, against a vendor's 3-month quote, from core bug fixes through Play Store launch.
- ✶Cleared a major feature and bug backlog, bringing an inherited codebase to its first production-ready state.
SDE Intern → SDE 1 → SDE 2
- ✶Co-developed a meta-driven no-code UI engine (form + list, React + TypeScript), cutting UI development time by 30%.
- ✶Built a shared component & service library for web and mobile in an NX monorepo (dependency injection, atomic design) — including an auto-generated API SDK and a unified Redux store.
- ✶Built ~80% of the frontend for the product that later became the Fhynix app — which I went on to lead.
SDE 1
- ✶Built real-time systems with Sockets for the Patiala Foundation — a scalable Node.js REST API with live inventory for a helmet-rental service.
- ✶Built multi-blackspot accident-area identification with real-time insights using Google Maps, in collaboration with Punjab Police.
- ✶Digitised end-to-end case filing: role-based workflows (RBAC), approval mechanisms, and automated PDF generation.
What I work with
Selected work
Fhynix — AI Calendar App
A React Native calendar productivity app on iOS + Android, serving hundreds of active users. As Head of Engineering I owned the whole stack — and built its three hardest pieces: an LLM assistant (no AI server, ~$10/month), an rrule recurrence engine with live migration, and a self-built IAP subscription system.
Chat with PDF
Upload a PDF and ask it questions. Retrieved chunks are reranked with a cross-encoder, and answers from GPT-4o-mini cite page numbers. Gradio UI.
InterviewIQ
A tool-calling mock-interview coach with a hand-written agent loop (no framework), retries, a session scorecard that finds your weakest area, and a two-agent mode.
Travel Assistant
A multi-step planning agent that chains weather, packing and cost tools on its own, then checks the plan against your budget.
Chandigarh Police — Social Complaints Monitor
A real-time portal that watches Twitter for complaints tagged to Chandigarh Police (#chandigarhpolice, #crime, #pcr) and surfaces them for action. Built in a 36-hour hackathon — recognized by Chandigarh Police.
Public Bus Location Tracking
Real-time location tracking for public buses to cut waiting times — buses POST their location and the server broadcasts to riders live. My most-developed personal repo.
Google Maps Reviews Scraper
A small Python scraper that pulls reviews from a Google Maps link and saves them to an XLSX file for analysis. Built for educational purposes.
