Advisor · Architecture & AI Systems
Advising ViziSmart, an AI property-management platform, on their technical architecture — system design (HLD/LLD) across their web and mobile apps, scalability, and the shape of their AI systems: visual-detection inspections, an AI chatbot, and a voice agent.

Founding Engineer · Lead Frontend
Founding engineer on PadhAI, SigIQ's AI-tutoring platform for India's toughest exam. Built the product zero to one — a retrieval-augmented tutor that answers with citations, AI evaluation of long-form answers, and live 1-v-1 quiz battles — shipped across web, Android, and desktop from a single codebase, with the AWS infrastructure and CI/CD behind it. 200,000+ learners in six months; the engine scored 175/200 on the 2024 UPSC Prelims.
Led EverTutor, our real-time voice tutor: a speech-to-text → LLM → text-to-speech pipeline with a shared whiteboard, modeled as a deterministic multi-modal state machine (voice ↔ chat ↔ draw). #1 Product of the Day on Product Hunt; 40% engagement lift.
Also ran our agentic software factory: Phoenix, an automated agent that reads the codebase and reviews every pull request, plus live-ops automation — spec → build → test → review loops with human ship-gates.

Frontend Engineer → Senior Frontend Engineer
Two stints. Built and maintained the React Native investor platform serving 1M+ users — real-time market data, portfolio management, order execution — and core design-system components documented in Storybook. Returned in 2024 as a senior engineer to build advanced trading-chart features and mentor the frontend team.
2021 – 2023
Frontend Engineer
Fully remote with the Singapore team. Re-architected new-user onboarding with a server-driven UI approach — the server decides each next step from user state, so flows iterate without app releases. 40% lift in new-user retention.

Situation
I joined SigIQ as a founding engineer with a one-line brief: build an AI tutor for UPSC, India's toughest exam — a million candidates, no spec, no team, no playbook.
What I did
I broke the ambiguity into shippable slices and led with the sharpest pain: doubt-solving. Shipped a retrieval-augmented tutor that answers with citations, then layered on answer evaluation and live 1-v-1 quiz battles. Chose boring-but-leveraged tech — one web codebase shipped to web, Android, and desktop via PWA-in-WebView — and built the CI/CD pipeline and AWS infrastructure myself. Weekly student cohorts were the feedback loop; what confused them got rebuilt.
Result
200,000+ learners in six months, 100k+ installs at 4.5★, and the engine scored 175/200 on the 2024 UPSC Prelims — part of the platform behind SigIQ's $9.5M seed.
Hardest part
The hardest part was balancing evaluation quality against ship speed — a tutor that's wrong is worse than no tutor. I set a rule: no AI feature ships without a citation trail or an eval gate.
