At Punch, I build real-time fintech systems for an Indian stock broker, from order management and automated KYC onboarding to React trading experiences with live orders, positions, charts, and NSE/BSE integrations. I reduced worst-case order splits from 67 to 2, cut per-trade brokerage up to 30x, and improved e-sign PDF generation from about 40 seconds to 2–4 seconds per application.
I've also shipped practice trading, Mux-powered screen streaming, and an in-house referral system that replaced an external vendor and saves about $45K annually. I work with Elixir, React, PostgreSQL, Redis, NATS, and AI-augmented spec-driven workflows, while mentoring three junior frontend engineers.
