At Fexen Smart Solution, I designed and scaled a NestJS microservices-based cryptocurrency exchange serving 5,000+ active users, reducing API latency by 30%. I also integrated OpenAI and Anthropic APIs into OverOS, an agentic automation platform for natural-language workflows.

I built AI-powered fintech features for KA$HY AI, including gamified rewards, referral engines, and P2P trading flows. For a SaaS screen-recording platform, I implemented Stripe subscriptions, billing, and webhook handling.

At O'Cyber LLP, I led end-to-end development of Rugby.xyz, including its player management system, live scoring engine, and performance dashboards. I also built a real-time communication SDK with LiveKit for calls, meetings, webinars, and broadcasts.

I solely built and maintained Ustaad, a school management platform covering student records, assessments, attendance, results, fees, billing, and administrative workflows. Across my work, I’ve developed full-stack products using React, Next.js, Node.js, and NestJS.
