Senior Software Engineer at dLocal who built resilient payment routing and transaction workflows.

Kenya

Message

At Dlocal - Strategic Contractor Engagement, I led development of a payment proxy for routing transactions between AZA systems and dLocal. I also designed resilient payment workflows with retry logic and failure handling.

At AZA Finance, I designed and built REST API integrations with banks and financial institutions, and developed an extensible third-party API layer that improved data exchange efficiency by 40% and reduced manual data entry by 50%.

I owned the design and implementation of payment and compliance systems, including the SARB mandate workflow. I also developed automated beneficiary screening workflows and background processing for notifications, beneficiary updates, and transactions.

Earlier, I developed Ruby on Rails and React features at TKXS(now Telus Agriculture), where database and backend optimizations reduced reporting latency by 40%. At E-kraal Innovation Hub, I designed and deployed a case management system handling over 100K cases monthly.
