Have a half-finished product, or a SaaS idea that needs billing, hosting and real users behind it? I build full-stack web apps or take over existing ones, then keep them running in production. Top Rated Plus | 1,800+ hours on Upwork | $25K+ earned | 5-star feedback on every rated contract RECENT WORK I took over a half-finished e-learning platform, completed it and launched it to production. I now run it end-to-end: Nuxt and PostgreSQL on AWS (ECS, RDS, S3, CloudFront), with recurring subscriptions in 3 currencies through Stripe, MercadoPago and PayPal. Before that, I spent 2 years building multi-tenant SaaS platforms (scheduling, CRM, inventory and analytics dashboards) used daily by real businesses. WHAT I CAN OWN FOR YOU • Full-stack apps in TypeScript with Nuxt, Vue 3, Next.js and React, from new builds to existing codebases • Backends and REST APIs in Node.js, Go, PHP and Laravel, with PostgreSQL data modeling • SaaS dashboards, admin panels and multi-tenant platforms • Payments with Stripe, MercadoPago and PayPal: subscriptions, upgrades and webhooks • AWS deployment and operations (ECS, RDS, S3, CloudFront, Lambda) and CI/CD with GitHub Actions • AI features: connecting language models, structured outputs and MCP tools to real business data • SEO, i18n and performance optimization HOW I WORK I use AI coding agents daily to ship faster, and I review and own everything that reaches production. I communicate clearly when scope changes, so there are no surprises. One client kept me on for ongoing maintenance and AWS support after the project ended, and a client review recommends me as "a reliable, flexible, and highly professional developer." Tell me what you're building or what's broken, and I'll tell you how I'd approach it.
