A SaaS founder was manually answering client messages until midnight every
night. I built an AI chatbot in 2 weeks. It now handles 257 conversations
monthly, serves 532 clients, and cut their costs by 43.8%.
I build AI-powered SaaS products that save time and generate
real revenue from day one.
I am a Multi-Tenant Full-Stack SaaS Developer with several years of experience
building production-grade, AI-powered SaaS platforms from concept to launch
across HealthTech, FinTech, EdTech, and B2B industries.
I work with US, UK, and EU-based startups (comfortable across PST to CET time
zones) and specialize in systems built to handle real users, real data, and
real revenue — not throwaway prototypes.
When you hire me, you're not just getting a developer who writes code. You're
getting a technical partner who thinks about your product, your users, and
your growth.

➤ Lovable.dev MVPs. End-to-end product builds: SaaS dashboards, two-sided marketplaces, internal tools, AI-powered applications, founder and client portals. Properly architected Supabase backends, secure auth, Stripe billing, real-time features.
➤ Claude Code Engineering. Production AI features built with the full harness in place: CLAUDE.md system prompts, MCP servers, sub-agent orchestration, token budgeting, structured outputs, and evals. The work senior teams need when they've moved past "look what the AI wrote" and into "why does this cost $4,000 a month and still hallucinate."
➤ MCP Server Development. Custom Model Context Protocol servers that connect Claude Code to your real infrastructure: repos, APIs, databases, internal tools, CRMs. Properly authenticated, scoped, and logged.
➤ AI App Rescue. Broken Lovable builds, unstable Replit deployments, runaway Claude API integrations, Supabase auth that locks users out. I diagnose, refactor, harden, and document.

Most founders spend months waiting on developers then get a half-built product that costs more than planned and still isn't ready for real users. I solve that.
I'm an AI MVP Developer specializing in rapid SaaS prototyping, no-code web application development, AI integration, and workflow automation. Using Lovable, Base44, Supabase, and Cursor, I help startups, SaaS founders, and businesses go from raw idea to fully working product faster and cheaper than traditional development ever could.
WHAT I BUILD FOR YOU
SaaS MVPs and Web Applications
I build minimum viable products from the ground up lean, functional, and ready for real users. Every MVP is scoped to prove your core value proposition fast so you can attract investors, gather feedback, and generate revenue without wasting months in development.
Admin Dashboards and Internal Tools
I build custom dashboards and internal tools that give your team real visibility and efficiency user management panels, operational dashboards, and client-facing portals that your team will actually use every day.
Micro-SaaS Products
Focused, single-purpose software solving one specific problem for a specific audience. I build micro-SaaS products that launch fast, monetize cleanly, and grow without constant developer involvement.
AI-Integrated Applications
I integrate AI capabilities directly into your application whether that's an AI-powered feature, an intelligent workflow built around a language model, or a fully AI-native product built from scratch.
Workflow Automation and API Integrations
Manual processes kill productivity. I build automation systems using n8n and AI-powered pipelines that eliminate repetitive work, connect your tools through smart API integrations, and keep your business running without manual intervention.
HOW I WORK
I use an AI-assisted, vibe coding development approach combining the most powerful modern no-code and AI-native platforms to ship production-ready applications at a speed traditional development cannot match.
Lovable Full-stack web apps built fast. Production-grade interfaces connected to real back-end logic, deployed quickly and built to last.
Base44 An AI-native platform for rapid full-stack application generation. Few freelancers on Upwork work seriously with Base44 this is a real competitive advantage for your project.
Supabase Scalable database management, authentication, and real-time back-end infrastructure. Clean, secure, and ready to grow with your users.
Cursor AI-powered coding for precise custom logic when no-code platforms reach their limits. Speed of AI development plus accuracy of custom code.
WHO I WORK BEST WITH
— Startup founders validating a SaaS idea without a technical co-founder
— Entrepreneurs who need an MVP built fast to attract investors or early users
— Non-technical founders who need a clear, communicative technical partner
— Small businesses needing dashboards or automation without enterprise budgets
— Product owners adding AI integration to an existing workflow or application
WHY CLIENTS CHOOSE ME
Speed without sacrificing quality. Your runway is limited, your timeline is real, and your product needs to work not just look good in a demo. I build fast and I build right.
I think like a product person. I don't just execute instructions I think about what you're trying to achieve, flag what doesn't make sense, and help you make smarter decisions throughout the build.
Clear communication. No going silent. No unexpected deliveries. Regular updates, right questions asked upfront, and full alignment at every stage.
Honest timelines. I won't promise three days if it takes two weeks. I scope honestly and deliver on my commitments every time.
LET'S BUILD SOMETHING
If you need a SaaS MVP, web application, admin dashboard, micro SaaS product, workflow automation system, or AI integration built fast, built clean, by someone who understands what you're actually trying to build send me a message.
Tell me what you're working on. I'll respond quickly and give you honest feedback on how I can help.
The fastest path to your product starts with one conversation.
