What I'm looking for

I'm seeking senior backend or full-stack roles where reliability, throughput, developer experience, and measurable product impact matter.

Senior Backend / Full-Stack Software Engineer with 8+ years of experience building production web applications, business systems, microservices, and AI-powered products.

My primary expertise is Go and Node.js/NestJS, with PostgreSQL, MongoDB, Redis, RabbitMQ, gRPC, Docker, REST APIs, and event-driven architectures.

I have experience taking complex systems from development through production, including backend architecture, database design, asynchronous processing, integrations, performance optimization, debugging, and ongoing maintenance.

Selected results include:
• Improved production performance by 10–15×
• Reduced payroll errors by 95%
• Reduced manual adjustments by 80%
• Accelerated AI content creation by 10×
• Helped launch a chat-based AI system reaching 10,000 monthly active users within two weeks
• Reduced a form-generation workflow from 1–2 days to under 30 minutes

I'm available for remote full-time, contract, and part-time engineering work, with a particular focus on backend and platform engineering.
