Full stack developer building web apps, SaaS platforms and AI features with React, NextJS, NodeJS, TypeScript and PostgreSQL, from the first screen to the live server. Top Rated on Upwork with 160+ jobs and $200K+ earned. I started as a web designer, so the apps I build don't just work, they look finished. Today most of my work is custom software that businesses run on every day: CRMs, dashboards, marketplaces, booking systems, mobile apps and AI tools. WHAT I BUILD • SaaS products and MVPs: user accounts, roles and permissions, subscriptions, Stripe or Square payments, admin panels • CRMs, dashboards and internal tools that replace spreadsheets and manual email • Marketplaces and booking platforms: listings, quotes, escrow, orders and real-time chat • AI features: OpenAI, Claude and Gemini integrations, AI agents, chat over your own data, speech-to-text, OCR, and self-hosted models when your data has to stay private • iOS and Android apps (React Native, Capacitor) that share code with your web app • WhatsApp bots and business automations • Taking over an existing app: I read the code, fix what's broken, set up proper deployment and document how it all works RECENT PROJECTS • Media-monitoring platform: records TV, radio and newspapers around the clock, transcribes and OCRs everything with self-hosted AI, and sends daily PDF reports by WhatsApp and email. Monitors 26+ radio stations for government clients. • Operations hub for a media company: CRM, sales pipeline, projects, finance, HR and KPIs, plus a desktop app and time tracker. Delivered and handed over to the client. • B2B marketplace for data-center cabling: customers post projects, verified installers send quotes, and work runs under escrow, with iOS and Android apps. • Restaurant platform: QR table ordering, live kitchen display, WhatsApp ordering bot and recipe-level stock tracking. • School management system: 22 modules including admissions, fees, exams with PDF report cards, timetables, a parent app and online classes. • AI clinical notes app for psychologists: records a session, transcribes it and drafts structured notes, on web and mobile.

HOW I WORK • I start with the business problem and propose the smallest version that solves it • Milestones with a working demo every week, so you always see progress • Clean code in your repository, deployed to accounts you own, with documentation • I use AI coding tools (Claude Code, Codex) to move faster, and I review, test and own every line I ship • Clear English and fast replies, all on Upwork Message me with what you want to build. I'll reply with how I'd approach it, a realistic timeline and a fixed price or hourly estimate.
