What I'm looking for

I’m looking to build production software—especially SDKs, APIs, and developer platforms—turning ambiguous ideas into scoped deliverables, improving performance and reliability, and shipping maintainable solutions in fast-moving teams.

I’m a senior full-stack software engineer with 7+ years of experience building production web applications, SDKs, developer platforms, dashboards, AI-powered tools, and APIs across finance, education, project management, logistics, AI tooling, and consulting. I’m strongest when requirements are ambiguous—I turn them into scoped deliverables, then ship maintainable software with confidence.

Most recently, I’ve improved Joyfill’s SDK end-user UX by shipping feature enhancements and reducing friction in core workflows. I’ve also diagnosed and fixed performance issues by profiling bottlenecks, isolating root causes, and validating improvements—so downstream teams can move faster with fewer regressions.

Previously, as Lead Engineer at Relentless Persistence Inc., I led engineering for SprintZero in an early-stage, fast-changing environment. I owned architectural direction and execution planning, introduced practical engineering discipline with incremental releases and smallest testable slices, and built maintainable patterns and clear interfaces so the codebase could evolve quickly.

Earlier in my career, I contributed to robust platform architecture at NativShark and streamlined integrations for clients at Lopworks Limited. Across roles, my professional ethos is consistent: debug complex issues methodically, improve performance and reliability, and collaborate closely with PM and engineering stakeholders to translate goals into predictable delivery.
