I help founders and small teams build, fix, and improve production web apps, SaaS dashboards, APIs, and AI automation workflows.
I’m a Senior Full-Stack Developer with 8+ years of experience across React, Next.js, TypeScript, Node.js, PostgreSQL, MySQL, TypeORM, Prisma, Supabase, REST APIs, PHP/CodeIgniter, and AI/API integrations.
I’m usually most useful when a product is already real — users depend on it, the codebase has history, bugs are blocking progress, workflows are messy, and the team needs someone who can understand the system and ship carefully without breaking existing users.
Here’s what I can help with:
1. Full-Stack Web Apps
* React, Next.js, TypeScript, Node.js
* SaaS dashboards, admin panels, portals, booking/contact flows
* Clean UI implementation connected to real backend data
2. Backend, APIs & Databases
* REST APIs, webhooks, integrations, auth, roles and permissions
* PostgreSQL, MySQL, TypeORM, Prisma, Supabase
* Database workflows, migrations, reporting logic, and production bug fixes
3. AI & Automation Workflows
* OpenAI / Claude API integrations
* AI-assisted business workflows, email automation, AI receptionist-style systems
* n8n-style automations, structured outputs, lead/customer communication flows
4. Existing Product Takeover & Debugging
* Understanding inherited codebases
* Fixing complex business logic
* Improving reliability, performance, and maintainability
* Clear communication about what is risky, what is broken, and what should be fixed first
I have worked on production systems involving registrations, permissions, user/admin workflows, payment-related logic, emails, dashboards, reporting, and business-critical processes.
I also have a scientific background in chemistry and computational research, which helps me work well on structured-data products, AI workflows, healthcare/science-related tools, vendor assessment systems, and complex business logic.
I’m Turkish, work internationally, and communicate clearly in English and Turkish. I work well with founders and teams who value practical decisions, honest communication, and reliable delivery.

I lead a team building scalable web, mobile, and SaaS products for startups and growing businesses. With React, React Native, and Node.js developers alongside UI/UX and Product Designers, we own the full product lifecycle - from MVP to stable production - delivering full-stack solutions built for long-term velocity and measurable business outcomes
🚀 𝗠𝗩𝗣 & 𝗦𝘁𝗮𝗿𝘁𝘂𝗽 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 We help founders move fast without sacrificing quality through agile full-stack development, mobile development, and React Native Developer workflows. Every MVP starts with a UX Designer and Product Designer working through user flows, wireframing, and prototyping in Figma before a single line of code is written. Our focus is on: 🎯 Turning ideas into working MVPs, building investor-ready demos, and launching beta products quickly
𝗢𝘂𝗿 𝘁𝗲𝗮𝗺 𝗱𝗲𝗹𝗶𝘃𝗲𝗿𝘀: ✅ Rapid MVP development (User Interface Design – Frontend – Backend) ✅ UX flows, wireframing, and prototyping by our Figma Designer team ✅ Production-ready code with React, Next.js, TypeScript, React Native, and Swift ✅ Secure third-party integrations (Stripe, Firebase, Auth0, Twilio, Google Maps) ✅ Clean, scalable architecture designed for long-term growth and SaaS solutions
As a Full Stack Developer SaaS team, we've helped startups raise funding and scale from MVP to 100,000+ users - and as a React Native Developer partner, we ensure your mobile product ships with the same precision as your web platform
💻 𝗪𝗲𝗯 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 Our React Frontend Developers, React Developers specializing in Next.js, and Node Developers work together to build fast, scalable web applications across the full stack - optimizing Core Web Vitals to achieve 95+ Lighthouse scores and 35% bundle reductions on Next.js TypeScript projects, because performance is never an afterthought. 🔹 Front-End: React.js, Next.js, TypeScript, JavaScript (ES6+), HTML5, CSS3, Tailwind CSS 🔹 Back-End: Node.js, NestJS, Express.js (REST & GraphQL), PostgreSQL, MongoDB, MySQL 🔹 CMS & Headless: Sanity, Contentful, Strapi
This collaboration between React Frontend Developers and Node Developers ensures clean, scalable code - a foundation especially critical for SaaS platforms and enterprise B2B products
📱 𝗠𝗼𝗯𝗶𝗹𝗲 𝗔𝗽𝗽 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 Our React Native Developers build mobile applications optimized for real-world usage, starting with UX mapping and UI design before development begins. As a Full Stack Developer, React Node team, we handle everything from UI to server-side logic: 🔹 React Native Developer Expo workflow for fast cross-platform delivery 🔹 Swift & SwiftUI for native iOS apps 🔹 Firebase, push notifications, analytics 🔹 App Store deployment and optimization 🔹 Offline mode, multi-language support, battery efficiency
Our approach enables rapid iteration and production-ready releases, with Node.js powering smooth mobile-backend communication
☁️ 𝗖𝗹𝗼𝘂𝗱, 𝗗𝗲𝘃𝗢𝗽𝘀 & 𝗦𝘆𝘀𝘁𝗲𝗺 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 Our Full Stack Developer React Node team designs and maintains reliable, production-ready infrastructure: 🔹 AWS: Lambda, EC2, S3, CloudFront, RDS, Docker, Kubernetes, Terraform 🔹 CI/CD pipelines (GitHub Actions, GitLab CI) 🔹 Monitoring & logging (Sentry, Prometheus, Grafana)
The goal: stable deployments, predictable scaling, and minimal downtime - essential for any serious Full Stack Developer SaaS platform handling real user load
🎨 𝗨𝗜/𝗨𝗫 𝗗𝗲𝘀𝗶𝗴𝗻 & 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 Our UI/UX Designers and Product Designers approach design as a core part of the product, not a decorative layer, working closely with Full Stack Developers so what gets built matches what was designed, pixel for pixel. Our Figma Designer workflow covers: 🔹 Product discovery & UX research 🔹 Wireframing and prototyping 🔹 Design systems and UI kits 🔹 Interface design across web and mobile 🔹 Accessibility (WCAG), responsive layouts
🤝 𝗛𝗼𝘄 𝗪𝗲 𝗪𝗼𝗿𝗸 🔹 Direct communication with our React Developers, React Native Developers, Full Stack Developers Node.js, UI/UX Designers, and Product Designers - no middle layers. As a dedicated Full Stack Developer React Node, and SaaS team, we bring every layer of the product under one roof: 🔹 Clear estimates and agile delivery 🔹 Clean, maintainable code 🔹 Secure API integrations with type safety in Next.js/TypeScript 🔹 Design and development moving together. Reliable products built by a team that understands both business goals and technical execution
