What I'm looking for

I’m interested in backend engineering, distributed systems, cloud infrastructure, and building reliable software that scales.

At CognoVerse, I reworked a core Node.js REST API’s pagination layer, reducing average production response latency by 100ms. I also delivered Common Carrier Phase 2, building its Node.js backend and React frontend.

I architected and solo-built Olive, a deliverable-tracking and workflow-orchestration platform using Fastify on Bun, TypeScript, PostgreSQL, and Redis Streams. It went from first commit to production in under two weeks, and I’m still its sole engineer in production.

For Olive, I designed an event-driven pipeline across four decoupled worker processes and built a storage abstraction supporting Google Drive and Microsoft OneDrive. I also implemented external magic-link workflows, internal JWT-based access, a zoomable Gantt chart, and an immutable audit log.

Earlier, I worked on AI-driven invoice and order processing, RAG proofs of concept, and real-time applications using Redis queues and Pub/Sub. I’m interested in backend engineering, distributed systems, cloud infrastructure, and building reliable software that scales.
