I build scalable fintech and high-traffic backend systems with NestJS, Golang, event-driven microservices, and reliable payment workflows.

At CredPal, I build backend APIs and microservices for cross-border payments, automated loan decisioning, and underwriter monitoring. I designed idempotent transfer workflows, RabbitMQ transaction pipelines, fraud and KYC checks, and reduced average loan decision time by approximately 75%.

Previously, I delivered appointment scheduling and tutoring-marketplace backends at TECHBEAVER, improving notification latency by 40%, API response times by 22%, and throughput by 30%. I’ve also built automated job-application workflows at JobGam and full-stack product features with React, Redux, Express.js, MongoDB, and TypeScript at UBUBA TECHNOLOGY.
