Over the past 5+ years, I've completed 212+ projects, earned over $100K on Upwork, and maintained a 100% Job Success Score while helping startups launch and scale successful mobile products.
Recent work includes the CeBee prediction platform with deep linking and referral systems, the Hajj Companion app used during pilgrimage by real users, and multiple marketplace and POS platforms designed for real businesses.
Whether you're building a new product or improving an existing app, I can help with:
▪ Flutter mobile apps for iOS & Android

▪ Long-term retainer support and post-launch iteration
I've shipped products across healthcare, fintech, e-commerce, logistics, POS systems, booking platforms, and AI applications—working with startups and established businesses worldwide.
What you can expect:
✔ Clean, scalable architecture built for long-term growth
✔ Fast and transparent communication throughout the project
✔ Production-ready code that survives real users
✔ Full ownership from planning to launch
✔ A long-term technical partner, not just a task-taker

I help founders, startups, and growing businesses turn web app ideas into launched, revenue-ready products.
My work goes beyond simply completing development tasks. I help clients plan the right features, build the core product, launch faster, and set up the technical foundation needed to support real users, payments, admin workflows, automation, and business growth.
I specialize in SaaS platforms, MVPs, dashboards, customer portals, subscription systems, internal tools, and API-driven web applications. I also help founders clean up vibe-coded apps built with tools like Lovable, Bolt, Replit, Same, v0, or Cursor and turn them into stable, production-ready products that can support real users, payments, and business growth. For live applications, I provide ongoing maintenance and product support, including bug fixes, scaling, new features, performance improvements, deployment support, integrations, and technical cleanup.
A recent example is Alpha Security, a Netherlands-based security company that was running key operations through paper, spreadsheets, and manual follow-ups. I helped build a custom internal dashboard with multiple modules for security pass applications, job vacancy management, KPI tracking, and customer reviews. The system automated daily submissions and operational workflows, saving the team around 3+ hours every day.
I have 6+ years of experience as a Full Stack Developer working with JavaScript and TypeScript across the full stack. My main stack includes React, Next.js, Node.js, Express, MongoDB, PostgreSQL, REST APIs, authentication systems, payment integrations, automation workflows, and production deployments.
What makes my approach different is that I think about the product as a business, not just as code.
Before building, I help clarify what actually needs to be launched first, which features can wait, and how the product should be structured so it can support real users, payments, admin workflows, reporting, and future growth.
When the project is done, you will not just receive source code. You will get a working product, production-ready deployment, clean project structure, documentation, and a proper handover so your team or future developers can continue without confusion.
If you have a SaaS idea, MVP, dashboard, customer portal, AI-generated prototype, or existing web application that needs to be launched or improved, send me a message and I’ll help you figure out the fastest practical path to get it live and working.

Started with frontend work. Built UIs, fixed layouts and figured out how things connect. Then moved to backend, picked up databases, cloud setup and AI integrations along the way. Now I handle full stack projects on my own from start to finish.
Most of my clients have been startup founders with a solid idea who just needed someone to actually build it. I have worked across SaaS tools, automation systems, real-time apps and AI platforms in different industries.
I give honest timelines, send regular updates and stay on the project until everything is properly done.
