AI SaaS developer and automation engineer building AI-powered platforms, Flutter mobile apps, and workflow automation systems that help startups operate at 3× their current capacity, without 3× the headcount. My clients have raised $15M+, shipped apps with 10M+ downloads, and cut operational overhead by 40–70% after going live. Top 1% on Upwork. 30+ projects delivered. Zero open disputes. What I build: → AI agents and OpenAI/LangChain workflow integrations: Replacing repetitive manual tasks with intelligent automation pipelines that make decisions, trigger actions, and escalate exceptions without human input. → SaaS platforms, full-stack and production-ready: React, Node.js, Firebase, Supabase, architected to scale from 100 users to 100,000 without rewrites. → Flutter mobile apps (iOS and Android): Cross-platform development with real-time Firebase backends, Stripe payments, and App Store deployment handled end to end. → Custom admin dashboards, internal tools, and CRMs that replace spreadsheets: Built around how your team actually works. → MVP development for founders: From idea to working product to App Store in weeks, not months. How I work: Every project starts with a short architecture session before a line of code is written. Founders who have worked with developers who just start building know why this matters: scope clarity upfront saves 3–6 weeks of refactoring. You get weekly progress updates, async-friendly communication, and a system clean enough to hand to any developer after delivery. Recent results: $15M+ raised by clients using systems I built · 10M+ app downloads · 30+ projects delivered with zero open disputes on Upwork.

I build production-ready SaaS products that founders can launch, monetize, and scale without hiring a full dev team. From MVP architecture to multi-tenant platforms with Stripe billing and AI integrations, I own the full stack and deliver systems built for real growth. I help startups and growth-stage companies go from idea to a product that generates real revenue without the cost and overhead of a full engineering team. Most clients come to me because they need more than a developer. They need someone who understands SaaS architecture, makes the right technical decisions early, and ships something users actually want to pay for. The work I do most: ✦ SaaS MVP development: going from a validated idea to a live, paying product ✦ Multi-tenant platform architecture: built right from day one so it scales without being rebuilt ✦ Subscription billing systems: Stripe integration, pricing tiers, usage limits, and upgrade flows ✦ AI feature integrations: adding OpenAI-powered features into existing SaaS products to make them smarter ✦ CRM systems, dashboards, and internal tools: custom-built for how your team actually works ✦ Platform modernisation: taking brittle or legacy products and rebuilding them for scale What I deliver isn't just code: it's a working product: → SaaS products architected to handle growth without a full rebuild → Subscription systems designed to convert and retain users → Clean, maintainable codebases one person stays accountable for architecture, frontend, backend, integrations, and deployment If you're building a SaaS product or scaling an existing one, I'd love to hear what you're working on.

If you've built an app on Replit, Lovable, Base44 or Bolt.dev, I'm the guy who takes it across the finishing line. Over the past 2 years I've helped numerous entrepreneurs and startup founders take their application from their low code environment to production. I know quirks of each of these platforms and what changes to make to the application codebase to make it ready for go-live.
