What I'm looking for

I'm looking for a remote or hybrid role where I can build reliable backend and full-stack systems, work on distributed workflows and AI-powered applications, and contribute to architecture, performance, and technical mentorship.

At Unibird, I built Node.js and TypeScript backend services, Kafka-driven workflows, Stripe payment systems, and real-time chat features used in production. I improved database performance through indexing and query optimization, introduced Redis caching and idempotency strategies, and built resilient distributed workflows for payments and inventory.

I also deliver end-to-end features with React and Next.js, mentor junior developers, and am currently building an AI workspace with Next.js, PostgreSQL, Prisma, Redis, and multi-model LLM integrations.
