Ehsan Z.

18 years building software that ships, not just prototypes. I'm a full-stack and AI engineer who takes ideas from a blank repo to a live, paying product. I started freelancing in 2007 and have been delivering for clients worldwide ever since. Most recently I designed, built, and run [login to view URL], a production AI text-to-speech platform on Google Cloud (Gemini 2.5 + Cloud Text-to-Speech). It serves 5,600+ users and 38,000+ generations, with live payments across 8 countries, all built solo, end to end. That's the kind of complete ownership I bring to your project. What I build for you: • AI-powered apps - LLM / Gemini / OpenAI integration, RAG, chatbots, text-to-speech, automation • Full-stack web apps - Next.js, React, Node.js, TypeScript • Backend & APIs - REST APIs, C# / .NET, Java, MySQL / PostgreSQL • Cloud & deployment - Google Cloud, Vertex AI, Compute Engine, nginx, PM2 • Automation & data tools - C#/.NET utilities, web scraping, document processing (Java + Apache PDFBox) • Payment integration - Stripe, PayPal, local gateways • Plus the SEO and infrastructure that keep products fast and discoverable Why clients keep me around: • One accountable engineer who can scope, build, deploy, and maintain, no hand-offs • Clear communication and honest timelines , I'd rather under-promise and over-deliver • I care about results, not just shipping code: your product working in the real world is the goal • I also train and mentor developers, so I can scale to a small team for larger builds Whether it's adding an AI feature to an existing product, building a full web app from scratch, automating a task that eats your hours, or deploying to the cloud the right way, I can help. Tell me what you're trying to build. I'll be honest about whether I'm the right fit, and if I am, exactly how I'd approach it.
