What I'm looking for

I'm looking to build scalable backend and distributed systems, especially around payments, event-driven platforms, cloud infrastructure, and AI-powered product features.

At Swivl, I build and scale NestJS and Go services for a field-service platform used by 10,000+ businesses. I've delivered payment and billing infrastructure, event-driven notifications reaching 300K+ monthly, GPS tracking, and media pipelines that reduced payload size by 85%.

I've also built AI Estimate and AI Receptionist services using FastAPI, LangGraph, gRPC, Twilio, and Retell AI, reducing estimate creation time by 70% and capturing 80% of inbound leads. Across CryptoPool, Alts Wealth, and LiteCode, I've shipped payment integrations, REST APIs, real-time systems, web and mobile products, and secure asynchronous grading infrastructure.
