Idea to production — web, mobile, and AI — shipped on time, with code you fully own. Over 12+ years and 600+ delivered projects, we've built our reputation on three things: code that holds up under real users, communication that never goes silent mid-project, and delivery that lands on the date we promised. WHAT WE BUILD • AI & Automation — LLM apps (Claude, OpenAI, Gemini), RAG pipelines, AI agents & chatbots with memory, document & workflow automation, AI-assisted internal tools • Web apps — React, Next.js, Node.js, Laravel, PHP, headless CMS • Mobile apps — Flutter, native iOS & Android • SaaS, CRM & ERP platforms; cloud, DevOps & migrations • UI/UX design & brand identity WHY CLIENTS CHOOSE US • CMMI Level 5 — the top ~1% of software teams for process maturity • Preferred Freelancer, 4.9★ across 650+ reviews, 99% job completion • A full team on every project — BA, PM, designers, DevOps & QA — not a lone coder • A dedicated project manager, so you always know status without chasing us • We flag risks early instead of going quiet — the #1 thing clients say they were burned by before • You own 100% of the code — no lock-in Industries: Healthcare, Fintech, E-commerce, Logistics, EV/Mobility, Education, SaaS. We're the right fit if you want a team that thinks about your product, not just your ticket — one that tells you what to build with AI, and what not to. Tell us what you're building and we'll reply within a few hours. menos -

I work across both frontend and backend development, with strong experience in: • SaaS platforms and internal dashboards • Marketplace and subscription-based applications • AI integrations and workflow automation • Realtime systems and WebSocket features • Stripe payments and third-party API integrations • Responsive, production-ready UI implementation • Performance optimization and maintainable architecture Core stack: * React / Next.js / TypeScript * Node.js / Express / PostgreSQL * Tailwind CSS * Supabase / Firebase * Stripe / OpenAI APIs * Docker / DigitalOcean / Vercel Clients usually work with me because I can: * Contribute beyond implementation * Communicate clearly and reliably * Work independently with minimal supervision * Balance fast iteration with maintainable code * Think about scalability and long-term product quality I’m comfortable joining existing products, improving unstable systems, building new features, or helping shape MVPs from the ground up.
