What I'm looking for

I seek backend- or architecture-focused roles at companies valuing high-scale, event-driven systems, strong testing culture, and opportunities to lead technical strategy.

I am a Senior Backend Node.js engineer with 9+ years designing high-load distributed systems and microservices using Node.js, TypeScript, NestJS, PostgreSQL, Redis, ElasticSearch, Kafka, RabbitMQ, and AWS. I have architected five enterprise-grade systems from scratch and delivered platforms handling 50M+ records and 20K+ documents daily.

I drive full SDLC delivery with Docker, Kubernetes, and GitLab CI/CD, achieving 79% automated test coverage with Jest and related tools. My experience spans LegalTech, IoT, HealthTech, E-commerce, FinTech, Crypto, Web3, and Blockchain markets across the US, Switzerland, and Europe.

I have led engineering teams, conducted hiring and mentoring, established coding standards, and improved frontend SEO by 65% using React.js and Next.js. I focus on building resilient, event-driven architectures and delivering measurable performance and reliability improvements.
