I build AI systems that make it from notebook to production, LLM-powered apps, computer vision pipelines, and ML models that ship and stay reliable. With a PhD-level background in AI and 8+ years across data science and full-stack engineering, I help startups and teams turn messy data and ambitious ideas into deployed products that work.
My research roots are in healthcare and medical-imaging AI, so I'm comfortable with the hard parts: noisy data, uncertainty, and models that have to be trustworthy, not just accurate.

I build AI integrations, full-stack apps and agentic systems that save businesses real money — $75K a year for one client, 3 days of manual work cut to 30 minutes for another. 🔸 Top 1% Expert-Vetted 🔸 100% Job Success 🔸 $400K+ earned 🔸 4,000+ hours
AI integration live in 2–3 weeks. Full SaaS MVP in 8–12 weeks. Production systems, not prototypes.

⚙️ HOW WE WORK
🔹 Free discovery session — I map your process, pressure-test the idea, and tell you honestly whether AI is the right answer. Some clients leave this call knowing they don't need me yet.
🔹 Architecture and scope — clear technical plan, timeline, and success criteria before any code.
🔹 Build in sprints — working software you can see and use every week, deployed automatically.
🔹Launch and handover — documentation, training, and support so you're not dependent on me forever.

I build and run production full-stack apps, mobile apps, and large-scale scrapers — fast.
Top Rated on Upwork with 471 jobs delivered, $700K+ earned, 100% Job Success, and over 10,000 hours in the seat.
My edge: I'm an AI-augmented developer. I use modern AI coding tools as a daily co-pilot, which means I ship features and ship them well-tested in less calendar time than a typical full-stack contractor.
You get more app per dollar — not because I cut corners, but because I'm at the front of how senior engineers work in 2026.
What I'm best at:
Full-stack web apps on Cloudflare Pages + Supabase + Next.js / React. Auth, real-time, edge — production from day one.
Mobile apps (React Native and native), shipped to App Store and Play Store, with the backend wired to the same Supabase or AWS stack.
AWS infrastructure — ECS, ECR, EC2, Lambda, RDS. From a single Docker container to a full Terraform-managed environment.
Large-scale web scraping — Python, Playwright, Selenium, rotating proxies, anti-block, dashboards, scheduling. I've built and maintained 15,000+ scrapers and 70+ data-aggregation bots delivering 300K+ data points per minute.
High-traffic site operation — building it is one thing, keeping it up at peak load is another. I handle both.
How I work:
Free 48-hour audit before you hire. Describe your project or share the codebase, and I'll come back with a written plan, stack recommendation, and rough cost.
First working version in 14 days for most projects.
Clear weekly updates. I don't disappear.
I'm the managing partner at Smart Maple, a 12-person software studio, so when projects need a team I can scale up — you still work with me directly as engineer of record.
Recent client wins:
"Mehmet did a great job from start to finish. He communicated clearly throughout the project, asked the right questions upfront, and delivered exactly what was scoped. No surprises, no chasing."
"Mehmet completed his projects on time and to required specifications. I would rehire if needed."
"Mehmet and his team did great work for us across 10+ different scrapers, integrated with our chosen backend, and deployed exactly how we needed."
Stack I work in daily:
TypeScript, JavaScript, Python, React, Next.js, Node.js, React Native, Cloudflare Pages, Cloudflare Workers, Supabase, PostgreSQL, AWS (ECS, ECR, EC2, Lambda, RDS, S3), Docker, GitHub Actions, Playwright, Selenium, Scrapy.
Got a project? Send the brief or repo and I'll come back inside 48 hours with a free audit and a clear plan.

Have an app idea but don't know where to start?
Need to modernize existing software, integrate AI, automate business processes, or build a product that can grow with your business?
You're in the right place.
Building software isn't just about writing code. It's about making the right decisions from the beginning. The wrong technology, poor planning, or rushed development can cost months of time and thousands of dollars later.
That's where I help.
I work with startups, founders, and businesses that need more than someone who can code. They need a trusted technology partner who understands business goals, recommends the right solutions, and builds software that's designed to grow.
Whether you're starting with a rough idea or improving an existing platform, I'll help you move from planning to launch with confidence while avoiding unnecessary complexity and costly mistakes.
You focus on your business. I'll handle the technology.
𝗛𝗼𝘄 𝗜 𝗛𝗲𝗹𝗽
Every project is different, so every solution should be too.
I help businesses:
• Turn ideas into clear product roadmaps
• Validate ideas with MVPs before large investments
• Build SaaS platforms, AI solutions, web applications, and mobile apps
• Modernize legacy systems and improve existing products
• Automate repetitive business processes
• Integrate payment gateways, third-party APIs, and enterprise systems
• Design secure, scalable, and cost-effective cloud solutions
• Continue improving products after launch with long-term support and new features
𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗧𝗵𝗮𝘁 𝗠𝗮𝗸𝗲𝘀 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗦𝗲𝗻𝘀𝗲
Technology should help your business, not become another problem to manage.
For example, if you're building an app for both iOS and Android, a cross-platform approach can often reduce development costs and future maintenance while delivering an excellent user experience.
If you're launching a startup, we'll identify the smallest version of your product that delivers real value so you can validate your idea before making a larger investment.
If AI can genuinely improve productivity, reduce manual work, or create a better customer experience, I'll show you where it adds value. If it doesn't, I'll recommend a simpler solution instead.
Every recommendation starts with one simple question:
"What's the smartest investment for your business?"
𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗖𝗵𝗼𝗼𝘀𝗲 𝗠𝗲
Technology is only part of a successful project. Communication, planning, and honest advice matter just as much.
When we work together, you can expect:
• Clear communication without unnecessary technical jargon
• Practical recommendations focused on business outcomes
• Transparent milestones and regular progress updates
• Clean, scalable, and maintainable solutions
• Honest feedback, even when a simpler solution is the better choice
• A long-term partner who stays invested after launch
My goal isn't to build another application.
My goal is to build software that helps your business grow.
𝗣𝗿𝗼𝘃𝗲𝗻 𝗥𝗲𝘀𝘂𝗹𝘁𝘀
I've partnered with startups, growing businesses, and enterprise organizations across Healthcare, FinTech, SaaS, AI, Logistics, E-Commerce, Real Estate, Government, and Enterprise Software.
Highlights include:
• 90+ Successful Projects Delivered
• $200K+ Earned on Upwork
• Products Serving 200,000+ Active Users
• Long-Term Partnerships Across Multiple Industries
𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 & 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀
From MVPs to enterprise platforms, I help clients build reliable, scalable software using modern technologies including React, Angular, Next.js, Flutter, React Native, .NET, Python, Django, Node.js, AWS, Microsoft Azure, Docker, SQL Server, PostgreSQL, Firebase, OpenAI, AI automation, cloud architecture, payment integrations, and enterprise APIs.
I don't recommend technologies because they're popular.
I recommend them because they're the right fit for your product, your budget, and your long-term goals.
𝗟𝗲𝘁'𝘀 𝗕𝘂𝗶𝗹𝗱 𝗦𝗼𝗺𝗲𝘁𝗵𝗶𝗻𝗴 𝗚𝗿𝗲𝗮𝘁
You don't need a detailed specification before reaching out. Some of my most successful projects started with a simple conversation and a rough idea.
Whether you're building your first startup, improving an existing platform, integrating AI, or scaling a growing business, I'd love to hear what you're working on.

As a Backend Developer I keep the Node.js layer predictable, documented, as a Node.js Developer I handle API Integration third-party services, database, frontend.
A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, Node.js backend, structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards, the permissions model so the product holds up as it grows.
