What I'm looking for

I'm looking for senior backend or full-stack roles where correctness, reliability, and product ownership matter, with opportunities to build workflow-heavy systems and lead technical delivery.

I've built banking, fintech, and enterprise software at Sterling Bank and Dufuna Technologies, delivering secure workflow platforms, REST APIs, third-party integrations, and transaction-focused systems.

At Sterling Bank, I led the architecture and full-stack delivery of a multi-module facility management platform using Next.js and Supabase/PostgreSQL, and delivered a travel loan platform in two weeks with flight API integrations, validation, workflow rules, and PDF generation. I work closely with compliance and operations teams on audit-sensitive requirements, role-based access controls, performance, and automation.

Previously, I led three engineers at Dufuna Technologies, owned technical decisions across products, and supported AWS deployments and Jenkins CI/CD. I also build independent systems such as a distributed wallet engine using ledger transactions, idempotency, Kafka, Redis, and transactional outbox patterns.
