What I'm looking for

I'm looking to build scalable, fault-tolerant cloud platforms and real-time distributed systems, contributing hands-on across architecture, microservices, performance, reliability, and deployment.

I've built high-throughput gaming platforms at Digitalix Inc, including dual-currency transaction flows, backend logic, and containerized microservices for the Weje platform.

I design event-driven systems with Node.js, Python FastAPI, Google Cloud Pub/Sub, Cloud Run, PostgreSQL, and Redis to support low-latency, high-concurrency workloads. I also own system reliability and performance tuning for consumer-facing marketplace features.

At Websultanate Software Technologies, I migrated a legacy monolith into a scalable Node.js microservices ecosystem, reducing infrastructure costs by 30%. I established CI/CD pipelines, observability metrics, and high-performance REST APIs for web and mobile clients.

I've also delivered real-time poker, RTMP streaming, NFT marketplace, and SEO-focused web products, working across React, Next.js, WebSockets, Web3.js, Strapi, and cloud infrastructure from architecture through deployment.
