What I'm looking for

I’m looking for USD contract work as a remote-first engineer where I can build production-grade full-stack systems—especially AI/LLM (RAG) and DevOps-driven delivery—while collaborating asynchronously with teams across time zones.

I’m a Senior Full-Stack Engineer with 4+ years designing, shipping, and scaling production systems used by 50,000+ users. I focus on building reliable APIs and interfaces that deliver measurable performance and operational stability.

I specialize in Python (FastAPI, Django) and Node.js with React/Next.js, and I integrate AI/LLM capabilities using LangChain, OpenAI, and RAG. I’ve shipped backends handling 10K+ RPM at 99.5% uptime, and I’ve built AI features that reduced manual workloads by 40%.

On the engineering side, I’ve led major backend re-architecture work—like migrating a legacy Django monolith into FastAPI microservices—improving API response times by 55% and enabling independent deployments. I also build DevOps automation, creating CI/CD pipelines and containerized release workflows that reduced deploy time from 2 hours to 15 minutes.

I’m remote-first and comfortable collaborating asynchronously across time zones, especially with US-based product owners and Agile sprints. I mentor junior engineers, raise quality through testing (55% to 85%+ test coverage), and I’m available immediately for USD contract roles.
