About

Professional summary

I am a full-stack and platform engineer with 4+ years of experience building scalable Node.js systems across IoT, SaaS, video analytics, and compliance-driven products.

I specialize in high-throughput data pipelines, multi-tenant architectures, and event-driven backend services. My work has included systems processing 10K+ events per minute and platforms handling 50,000+ daily transactions.

I have strong experience with Node.js, Express, Fastify, PostgreSQL, MySQL, MongoDB, Kafka, ClickHouse, MQTT, Docker, and cloud-based deployment workflows. I also enjoy improving performance, reliability, and developer productivity through automation and clean architecture.

A major part of my background is building privacy and compliance features, including GDPR/CCPA workflows, audit trails, encryption, and data retention systems. I am comfortable working in fast-paced environments where security, scale, and maintainability matter.

I have also taken on technical leadership responsibilities, mentoring junior engineers and leading backend delivery for production systems. I like collaborating with cross-functional teams to turn product requirements into robust technical solutions.

I am currently focused on backend and platform engineering opportunities where I can contribute to scalable infrastructure, real-time systems, and high-impact product development.
