Contract Backend / Full Stack Developer at SRD Exchange (2026-02 – 2026-06)
- Redesigned async transaction processing pipelines for a high-frequency trading exchange, reducing tail latency under peak load by isolating hot paths and tuning connection pooling and query batching.

Founding Engineer — Full Stack & Platform at OnlyFounders (2025-08 – 2026-05)
- Owned the full platform (frontend, backend, infra) for a Solana token launch product that sustained 5M+ concurrent connections, $20M+ trading volume, and 99.99% uptime through a 48-hour DDoS attack — mitigated via custom Nginx rate limiting and connection shaping (no third-party WAF).
- Built backpressure-aware WebSocket infrastructure with Redis pub/sub, ordered deduplication, and retry logic delivering sub-100ms price & orderbook feeds to thousands of clients under burst traffic.
- Delivered real-time trading UI in Next.js + Tailwind, live video/chat over WebSockets, and a React Native Solana Mobile app with production safeguards: dynamic fees, multi-layered anti-snipe protections, whale caps, and rate-limiting at thousands of TPS.

- Scaled backend APIs with Redis caching and query optimization for high-traffic learning flows; built a reusable React component library and shipped the Android app to Google Play Store.
