Kevin Patel

I’m a backend and full-stack engineer focused on building scalable systems and infrastructure-heavy applications. I enjoy working on problems involving distributed systems, real-time data processing, and backend architecture.

I’ve built projects like TradeSphere, a real-time trading platform with an in-memory order book, matching engine, and WebSocket-based streaming, where performance and system design were critical. I also developed ZapFlow, an event-driven workflow engine (similar to Zapier) using Kafka, PostgreSQL, and Node.js, implementing patterns like producer-consumer and transactional outbox for reliable async processing.

In my current role, I build and improve production backend systems involving asynchronous processing pipelines, API architecture, and system reliability. I've implemented layered security across 400+ APIs, built scalable usage-limit systems, and optimized Redis-backed data pipelines for 5x faster processing. Alongside this, I'm a long-term open-source contributor and Google Summer of Code 2023 participant with Checkstyle, where I contributed 200+ pull requests and resolved 420+ suppressed mutations.

Technically, I work primarily with Node.js, TypeScript, Java, PostgreSQL, Redis, and Kafka, and I’m comfortable designing APIs, building distributed systems, and working with cloud-native setups.

I'm looking for backend or backend-heavy full-stack roles where I can build scalable APIs, distributed and event-driven systems, real-time platforms, and reliable cloud infrastructure.
