What I'm looking for

I seek backend or full‑stack roles where I can build scalable SaaS platforms, own system design and performance improvements, work with cross-functional teams, and grow into technical leadership.

I am a software developer with over two years delivering high-impact web applications and scalable SaaS platforms, comfortable working in remote, cross-functional teams and leading small engineering groups.

I have architected multi-tenant payment-links SaaS on Cloudflare Workers, reduced API p95 latency by 88% through query and index redesign, and built production-grade inventory sync and invoice-generation pipelines using modern stacks like TypeScript, Bun/Hono, Drizzle, MedusaJS, PostgreSQL, and BullMQ.

I contribute full-stack expertise across Python and TypeScript ecosystems, have improved fintech and PropFirm systems by automating workflows and optimizing high-load SQL, and I am bilingual in English and Spanish, open to relocation and cross-border collaboration.
