What I'm looking for

I'm looking to build production-ready backend systems with a remote, cross-functional Agile team, where I can improve API reliability, architecture, automated testing, and continuous delivery.

At AND Digital, I designed and implemented a Redis caching layer for GraphQL resolvers that reduced database load by 40% and improved system stability.

I develop and maintain secure REST and GraphQL APIs with Nest.js and PostgreSQL, integrate third-party services, and implement JWT and OAuth authentication. I work closely with distributed Agile teams through planning, refinement, code reviews, and continuous delivery.

I've also built a booking system, a secure authentication service, and a backend freelance platform focused on roles and real-time interactions. I care about clean architecture, efficient API design, and automated testing.
