Senior Full-Stack Engineer | Laravel, React, TypeScript, PostgreSQL & AWS

I build SaaS products end to end, from Laravel APIs and high-volume data pipelines to React and TypeScript interfaces, with hands-on ownership from architecture through production.

About Me

I'm a Senior Full-Stack Engineer with 4+ years delivering SaaS products end to end, from Laravel APIs and data pipelines to React and TypeScript interfaces. I specialize in Laravel, React, TypeScript, Inertia.js, PostgreSQL, and AWS.

At Eliyce, I own full-stack architecture and delivery for Veros.ai, a global customs and trade-compliance platform. The product supports 10M+ records, 15K–20K monthly submissions, and operations across 45+ countries.

I engineer queue-driven ingestion, chunked imports, validation and transformation workflows, responsive operational interfaces, third-party integrations, automated tests, and S3-backed exports.

I lead delivery within an 8+ person cross-functional team and mentor 3–4 engineers across frontend, backend, testing, and production practices.

I build complete products: reliable backend systems, useful interfaces, and the delivery practices that connect them.

Looking for a senior engineer who can own both sides of the stack?
