I am a senior Back-End engineer with 8+ years of experience building scalable microservices and distributed systems on AWS.
I specialize in Node.js, NestJS, and Go, with a strong focus on designing clean, well-documented APIs (Swagger/OpenAPI) and event-driven architectures.
I’ve worked extensively with DDD and CQRS patterns, helping teams structure complex systems that are maintainable and easy to scale. In previous projects, I’ve improved system reliability and reduced latency by up to 40% through optimized AWS Lambda integrations, containerized CI/CD pipelines, and solid testing strategies (unit + integration).
My background also includes fintech solutions, where I’ve implemented wallet systems, KYC workflows, and secure, high-performance backend services within agile environments.
I enjoy working on challenging problems, optimizing performance, and building systems that scale reliably in production.
