I'm Dishant Sahu — full-stack developer at 404Minds, where I build realtime fleet telematics, and solo developer of Jumavo (healthcare payments) and WittyByte (AI interview prep). I own features end to end — schema design, APIs, UI, payments, and the monitoring that keeps them honest.

B.Tech in Electronics and Telecommunication at VSSUT. For my final-year project I implemented image encryption and decryption in hardware with Xilinx System Generator and validated it on an FPGA — I learned systems from the wires up.
Taught myself modern web development by shipping constantly: storefronts, a YouTube clone, WebRTC video chat, a Truecaller-style REST API. Most of it is still on GitHub — unpolished and public on purpose.
Joined a remote engineering team building fleet telematics: gRPC microservices, Go ingestion pipelines, ScyllaDB, and dashboards rendering 50,000+ live vehicles. 530+ of my pull requests have been merged since.
Nights and weekends became Jumavo and WittyByte — both live, both built end to end: product decisions, schema, payments, auth, observability, deploys.
A health wallet that pays providers upfront and helps patients save for the care they actually want. I designed and shipped the whole product alone: Stripe-backed wallet flows — top-ups, settlements, redemptions — provider, member, and admin portals, QR-code patient onboarding, and generated PDF statements, with Playwright end-to-end tests and Sentry watching production.
AI-powered interview prep for ML engineers, sold as monthly subscriptions. Voice interview simulations on Retell, a Monaco-based coding workspace, a curated question bank from top tech companies, and readiness scoring — plus the unglamorous parts that make it a business: Clerk auth with webhook sync, Stripe billing, and PostHog funnels.
A production platform tracking 50,000+ vehicles live. I build across it: gRPC/Protobuf microservices on ScyllaDB and PostgreSQL, Go ingestion consumers parsing GPS tracker protocols, Google Maps clustering dashboards, and geofence alerting that holds notification latency to about a minute.
2,007 contributions in the last twelve months. Most of it is private client and product work — GitHub counts it, and the profile confirms it.
