Message

I've built backend platforms at Klak, Omniswift Limited, Cloudfift Inc., and Divergent Enterprise across fintech, education, property management, and e-commerce.

At Klak, I developed financial automation for reconciliations, invoices, payments, and ERP integrations. I increased PDF bank-statement processing from 10 to 100+ pages, improved reconciliation performance by 30%, reduced manual processing by 70%, and supported $500K+ in transactions with 99.9% uptime.

I use Java, Spring Boot, Node.js, PostgreSQL, MySQL, MongoDB, AWS, Docker, CI/CD, and messaging tools to deliver secure APIs and distributed systems. I've also mentored junior engineers, optimized high-traffic applications, and built reliable payment, authentication, and role-based access systems.
