What I'm looking for

I seek senior engineering roles building scalable, reliable systems with strong cross-functional teams, impactful integrations, and growth into leadership.

I am a senior full-stack software engineer with extensive experience building scalable microservices and enterprise-grade integrations. I have worked across backend, frontend, and mobile stacks to deliver production systems for financial and telecom customers.

At nuSoft.co I collaborated with a global engineering team to develop 20+ NestJS microservices, integrate Kafka and PostgreSQL, and connect QuickBooks and Stripe to automate reconciliation for 100K+ monthly transactions. I also contributed to frontend work that improved payment completion rates and led a cross-functional team to deliver client milestones.

Earlier roles include optimizing a legacy Java monolith with Docker and improving network discovery performance at Fiber Mountain, and building .NET and SwiftUI solutions at Xgrid.co that enabled remote device control and offline jobsite sync. At Zong CMPak I implemented payment gateway integrations and HR portals that streamlined workflows for thousands of users.

I prioritize reliability, performance, and measurable impact—delivering zero-downtime updates, significant performance gains, and automation that saves teams time while expanding product eligibility in regulated environments.
