Most founders and small teams need one senior engineer who can own the whole product: frontend, backend, database, integrations, AI features and deployment, without coordinating three different developers. That is the work I do. Top Rated Plus on Upwork | $80K+ earned | 7+ years in production software | Available 30–40 hrs/week, usually as the sole engineer owning the full stack. WHAT I BUILD SaaS and finance products. Invoicing, expense tracking, bank reconciliation, VAT, subscriptions and reporting for real businesses. Fundsvisor and BookBI are AI-assisted accounting products used by UAE and Gulf SMEs; I built the receipt-scanning and auto-categorisation flows that cut manual data entry. AI integrated into existing systems, not demo wrappers. LLM features with structured outputs, tool use and fallbacks, running inside production apps. Examples: an MCP server for Serre, a B2B sales intelligence platform; WhatsApp Cloud API lead automation on a Laravel CRM with AI classification, scoring, summaries and automated replies; AI research and coaching workflows for StoryOS, a YouTube channel growth platform. I use Claude Code daily and review every line it produces. Taking over live products. Half-built or AI-generated codebases that need a senior owner: I map what exists, audit security and tenant isolation (Supabase RLS, secrets, permissions), fix what is broken in order of risk, set up staging, tests, backups and monitoring, and hand over documentation another engineer can follow. Mobile. Flutter apps for iOS and Android (BookBI, Fundsvisor, Flow) with auth, push notifications, in-app subscriptions and store deployment. React Native/Expo where the project calls for it. HOW I WORK - I read the whole codebase and business flow before proposing anything. - Written plan with risks and estimates before I touch production. - Short weekly update: what shipped, what is at risk, what I need from you. - I stay available after launch. Most of my contracts are long-term.

Full overlap with Gulf and EU hours, early-morning overlap with US East. Send me what you are building, even if it is rough. I will tell you how I would approach it and whether I am the right fit.
