Do you remember that scene in Pulp Fiction when Jules and Vincent are in a car covered in blood with a dead body in the backset, absolutely freaking out, and they have to call Mr. Wolf? He steps in, gets to the job site in record time, takes control of the situation and cleans up the mess that nobody else had any idea how to deal with. Or how about Saul Goodman in Breaking Bad when he leans in and says, "I know a guy... who knows a guy." Well on Upwork, I am that guy. Except instead of cleaning up crime scenes, I help companies navigate high-stakes, complex technical challenges across the modern web. I am the fixer you call when you’re dealing with intricate integrations, tricky third-party vendors, sometimes entirely undefined scenarios that require a steady hand. I’m the guy you call when your developer walks off the job because he doesn’t know how to communicate with other types of humans, or when they've forgotten that the actual purpose of a building a web app is to serve customers; not to build some monument to their own "ideal architecture" or experiment with a trendy new framework on your dime. Here is what I bring to the table: - Emergency Navigation: I step into high-stress, broken scenarios and stabilize them quickly. - Autonomous Problem Solving: You don't need to hand-hold me. I take complex, messy problems and carry them forward on my own. - Reliable Backup: I can seamlessly plug into your existing pipeline when your internal team is bottlenecked. 
 A few real-world problems I've solved recently:

 - advising, guiding and informing a CEO to uncover massive memory leaks across 5K web modules and teaching him and his 100 member dev team about memory profiling and how to ship code in a huge team with best practices so it won't happen again - fixing thorny analytics problems that span multiple Astro websites with platforms like TripleWhale, Stripe, LineUp, GTAG and Blotout for a famous London theatre company - took ownership of a complex, legacy app as a full stack lead web developer for over a year of a provincially run teaching platform in Canada that used frameworks that no one has ever heard and were completely undocumented - revolutionizing the way a 24M ARR company ships frontend code by building a proxying bundler that could bundle local code against any production server by modifying how a web browser functions If your project is off the rails, your deadline is ticking, or you just need an expert full-stack web developer that knows what they are doing, let’s talk. Drop me a message with your current bottleneck, and let’s see if I’m the right man for the job.

Full Stack AI Developer | AI MVP Expert in Claude Code, Lovable, Base44, Replit, Bolt & v0 I turn AI-built ideas into production ready apps that ship, scale, and get paid. Most founders don't need another developer. They need someone who can take an idea or a half working AI build and turn it into a real product before time and budget run out. That's exactly what I do. I'm a Full Stack AI Developer and AI MVP expert specializing in the modern vibe coding stack: Claude Code, Lovable, Base44, Replit, Bolt, v0, and Cursor, backed by React, Next.js, TypeScript, Node.js, Supabase, and Stripe. I take what these AI tools start and make it actually work stable, scalable, and ready for real users and real payments. Founders, startups, and agencies usually come to me in one of two situations: YOU HAVE AN IDEA AND NEED IT BUILT FAST I take you from concept to a launched MVP authentication, database, payments, and a clean, responsive UI using React, Next.js, TypeScript, Node.js, Tailwind CSS, and Supabase, with Stripe wired in so you can charge from day one. I build full stack web applications, SaaS platforms, AI apps, AI agents, and mobile apps (iOS and Android) that go live with little technical burden left on you OAuth, Stripe, environment keys, and third party integrations handled properly. YOU HAVE AN AI GENERATED APP THAT LOOKS GREAT BUT BREAKS Vibe coded apps built in Base44, Lovable, Replit, or Bolt often look impressive but fall apart on bugs, broken integrations, failed deployments, and code that won't scale. I specialize in inheriting and stabilizing existing builds auditing the architecture, finding the root cause, fixing it cleanly, and deploying to web or the App Store. If fixing one bug keeps triggering three more, that's exactly the kind of unstable build I stabilize and launch. WHAT I BUILD AND FIX AI MVP development, SaaS development, and AI app development AI agent development and automation (Claude API, OpenAI, Makecom, n8n, Zapier) Vibe coding cleanup, bug fixing, and debugging (Base44, Lovable, Replit, Bolt, v0, Cursor) Base44 app audits, feature expansion, and stabilization of complex existing builds Base44 to Supabase migration stripping proprietary wrappers, rebuilding auth, RLS, PostgreSQL Payment and subscription integration (Stripe, PayPal) Database and backend (Supabase, PostgreSQL, MongoDB, Redis, Firebase) API integration and webhooks (REST APIs, OAuth 2.0, third party tools) Voice AI and conversational AI (Twilio, OpenAI Realtime API, Retell.ai, Vapi) Mobile deployment Capacitor wrapping, push notifications, App Store and Play Store submission Workflow automation and internal dashboards (n8n, Make com, Airtable) Cloud deployment and CI/CD (AWS, Vercel, Railway, Netlify) A FEW EXAMPLES OF RECENT WORK Integrated Stripe subscriptions and handled full deployment for a Lovable SaaS app Fixed and shipped a Base44 meal planner app through API integration and targeted bug fixes Resolved a broken Replit build and managed full App Store submission Diagnosed and repaired an AI agent's architecture with clear root cause analysis In plain terms: I help founders, startups, and agencies turn AI built ideas into real, paying products using Claude Code, Lovable, Base44, Replit, and a modern full stack toolkit. WHY CLIENTS KEEP WORKING WITH ME Unlike developers who only write code, I focus on the whole product journey UX, architecture, scalability, payments, and long term growth. I've built AI-powered SaaS products, AI agents, voice receptionist and lead management platforms, automation systems, internal dashboards, and marketplace MVPs that solve real operational problems. What working with me looks like: Fast, proactive communication I don't go quiet mid project A visible win early, so you feel real progress in week one Clean, documented, maintainable code your team can build on Honest scoping I'll tell you upfront what it takes to ship My clients consistently highlight clear communication, quality, reliability, and ownership of outcomes and my reviews reflect that. WHO I WORK BEST WITH Startup founders launching a first AI MVP, agencies needing a reliable build or rescue partner, and growing businesses adding AI features, automation, or payments to an existing product whether you're starting from a blank canvas or a broken vibe coded build. HOW I WORK Discovery call → clear scope and timeline in plain language → focused milestones with an early win shipped fast and steady updates → thorough testing, clean deployment to web or App Store, and documentation your team can run with. LET'S TALK If you're building an AI MVP, fixing a Base44, Lovable, or Replit app, migrating off a platform, integrating Stripe, deploying AI agents, or modernizing an existing product send me a message with what you're working on and where it's stuck. I'll reply quickly and tell you honestly what it will take to ship it. Ready to turn your idea or your half finished build into a product people pay for?
