What I'm looking for

I'm looking for remote or international contract roles where I can lead Node.js backend architecture, build AI-integrated automation, own reliable APIs and microservices, and collaborate with distributed product teams.

At SeptSol, I own the backend for LuckXpress, a production social casino platform serving 100,000+ active players and generating approximately $200K in monthly revenue. I lead API design through production deployment while building AI-driven automation with LLM services, LangChain, n8n, and external APIs.

I’ve designed and deployed 20+ microservices using Kubernetes, Apache Kafka, CDN, API Gateway, load balancing, and Redis caching, reducing API response times by 60% and memory usage by 30%. I also guide code reviews, service boundaries, integration patterns, and backend quality across distributed teams.

My experience spans Node.js, Express.js, MongoDB, REST APIs, MERN applications, and React Native API support across SeptSol, SenewTech, Atrule Technologies, and GameberSok. I’ve owned data models, third-party integrations, production fixes, and stable API contracts for web and mobile products.
