What I'm looking for

I seek roles with end-to-end ownership of backend and platform systems, collaborative agile teams, opportunities to mentor engineers, and technical challenges in scalable, high-concurrency environments.

I am a senior software engineer with 5+ years building scalable backend systems and full-stack applications across healthcare, crypto, and finance. I specialize in API design, database architecture, and backend performance optimization, delivering secure and efficient systems that prioritize reliability and customer satisfaction.

At Invesko I built the core backend architecture from scratch using Fastify, Node.js and Golang, engineered real-time pipelines, integrated market APIs, and implemented AI-assisted anomaly detection to improve fraud monitoring. Previously, at PDAX I modernized a legacy ledger pipeline with Apache Kafka and PostgreSQL advisory locking, improving latency and ensuring transactional integrity.

I enjoy mentoring engineers, introducing modern engineering practices, and taking end-to-end ownership of products. I am technically versatile with strong proficiency in Node.js, React, Next.js, MySQL, Redis, Docker, and AWS, and I adapt quickly to new frameworks while maintaining a focus on code quality and operational excellence.
