What I'm looking for

I’m looking to build resilient, scalable backend and AI-first systems—especially for telecom and financial platforms. I want teams that value reliability, strong engineering practices, and modern cloud-native delivery, where AI-assisted development meaningfully accelerates outcomes.

I’m a Senior Software Engineer with 7+ years of experience building scalable backend systems, financial platforms, and cloud-native applications across telecom, banking, and digital agriculture ecosystems. I focus on designing microservices architectures, large-scale integrations, and resilient infrastructure that serves millions of users.

In my current role as a Senior AI First Software Developer, I build enterprise telecom billing and revenue management systems and deliver AI-assisted defect detection using Retrieval Augmented Generation (RAG) and vector search. I also develop AI-driven development workflows with autonomous development agents and integrate AI-assisted tooling into CI/CD pipelines to automate defect identification and resolution.

Earlier, I led integrations for digital banking services by exposing core banking capabilities as secure REST APIs through WSO2 API Manager and building microservices to connect core systems to digital platforms. I’ve also delivered high-impact initiatives like enabling loan disbursement infrastructure and supporting banking migrations at large customer scale, while strengthening observability and DevOps best practices.
