El SalvadorWhat I'm looking for
I’m a Full-Stack Software Engineer with 6+ years building scalable web applications for U.S. companies. I specialize in TypeScript, React/Next.js, and Node.js/NestJS, and I take pride in writing clean, maintainable code while optimizing performance and shipping on time.
Most recently, at Kargo Solutions, I defined and built the foundation blocks from scratch for a logistic platform. I’m delivering core features across modules—auth for multiple roles and permissions, a UI design system, architectural fundamentals like queue and cache systems, and AI-powered file extraction with agentic shipment orchestration using RAG and LLMs.
Earlier, I delivered an industrial service management system with offline-first capabilities, and built payment-heavy and AI-enhanced products like Stripe Checkout & Connect course marketplaces and AI-powered invoice processing with GPT-4o and Claude 3.5 (including fine-tuning for accuracy). I’ve also built enterprise compliance capabilities supporting SOC 2 and ISO 27001, optimized high-volume event processing query performance, and extended an enterprise audit management platform with data visualization and automated reporting.
