As a React Developer and Full Stack Developer I build custom Web Application products for B2B clients, from interface to backend. Most of my work is Full Stack Developer React Node delivery, where a React frontend and a Node.js backend support one business workflow end to end. As a Node.js Developer I own the REST API logic, authentication, roles and permissions, and the data layer behind each product. My focus is practical Web Application Development that ships, scales, and stays maintainable, with clean API Integration at the core.
Across 14+ years and 130+ completed projects I have built 60+ SaaS, CRM and dashboard products, 40+ admin panels and client portals, and 200+ REST API integrations. As a React Developer and Full Stack Developer with experience leading development teams of up to 6, I have shipped for 50+ EU and US B2B clients across SaaS platforms, CRM systems, marketplaces, booking websites and API Integration projects.
As a React Developer I build Web Application interfaces with React.js, Next.js, TypeScript and Responsive UI , wired to live data through API Integration . As a React Frontend Developer and Frontend Developer I deliver usable, fast interfaces — data tables, filters, admin panels and client portals.
On the backend side, as a Node.js Developer and Backend Developer I build the REST API layer, ExpressJS services, authentication, roles and permissions, payment flows and CRM integrations. Many clients come to me as a Node.js Developer when a frontend already exists but the API, the data model and the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable and documented, and as a Node.js Developer I handle the API Integration between third-party services, the database and the 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, a Node.js backend, a 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 and the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend and backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build.
I also work as a Directus Developer and Headless CMS Developer . On 20+ content-driven and data-heavy products I use Directus CMS or Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As a Directus Developer I model the data, set roles and permissions, and connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React Developer and Node.js Developer delivery.
Stack I use daily: React, React.js, Next.js, Node.js, TypeScript and JavaScript on the application side; ExpressJS, REST API and API Integration on the service side; SQL, MySQL, MongoDB, Firebase and Supabase for data; Directus CMS and Strapi for headless content. Authentication, roles and permissions, payment flows, dashboards, data tables, filters and admin workflows are standard parts of how I deliver Web Application Development .
How I work on a Full Stack Developer React Node project: discovery and scope first, then architecture and backlog, design where needed, development in sprints, QA on staging, production release, and support after launch. As a Web Developer with 14+ years behind me, my main promise is delivery predictability — clear scope and no surprises. As a JavaScript Developer I write code the next developer can actually read and extend.
Typical projects clients hire me for: SaaS platform development, CRM systems, admin panels, marketplaces, booking websites, lead generation websites, dashboards, client portals, internal business tools, e-commerce platforms and API-based Web Application work with workflow automation and business automation.
Clients also find me under related searches that match my real stack. On the React side: React Native Developer , React Native App Developer , React Next.js Developer , React Developer Firebase , and Full Stack Developer Supabase React . On the full stack side: Python Full Stack Developer , Full Stack Developer AI , Full Stack Developer Shopify , Full Stack React , Full Stack Node.js React and Node.js React . On the backend: Node.js Backend Developer and Back End Developer Node.js . I also fit Front-End Developer Full-Stack , Python Developer , WordPress Developer , Mobile App Developer and Senior Full Stack Developer .
If you need a React Developer , a Full Stack Developer React Node engineer, or a Node.js Developer for a serious product, I can take it from architecture through release and support. Let's talk about your product and what it needs to do.
Let's get in touch!

If 15 years as a lead developer turned solution architect sounds amazing, I am still learning while keeping a keen watch on technological advances. From SAAS-based business automation (ERP, CRM, industry-specific applications) to building a portfolio in niche domains like:
👉👉Healthcare and Logistics, Aviation, and AI, I have worked as a freelancer, team lead, and technical advisor as and when required.
**Though I love developing applications from scratch, I have an ample amount of work that includes**
✔ Working in collaboration with remote teams, offsite and onsite (Global Clients, Australian/US clients)
✔Migration of legacy applications as per Object Oriented Design, intuitive Single Page Application (SPA) interface with Angular 6, .NET Core, SQL SERVER 12/14, and Azure services.
✔Data analytics: PowerBI, SSRS, Tableau, DevExpress Reporting, Upscaling existing applications (features and performance enhancement, database management, etc.)
✔Entity Framework, ADO.NET, and API/ Microservices development
**Withstanding a decade-long technology advancement, there is more to what I can offer if you are a well-established business having a large customer base.**
👉Setting up your cloud infrastructure with Azure and AWS to avail shared and multi-tenant services so that you can handle unpredictable changes in user demand and balance across servers.
👉 Set up proper logging and monitoring to catch any performance problems or errors before they affect your business negatively.
👉 Set up continuous integration or track down and eliminate bugs to eliminate the possible human errors while deploying the new versions.
Apart from this, on-time delivery, a quick turnaround, and no-fuss behavior have earned me a good reputation and consistent client collaborations/Projects worth a few weeks to years🤗
And what's better than client feedback? Check reviews and the volume of work on my profile for various projects undertaken and successfully delivered.
Please ping me for a great work experience, I look forward to helping you scale!

I'm a versatile full stack developer and masters in computer science candidate at Clemson University with hands-on experience building robust web applications using Django, .NET, Laravel, Node/React, and Ruby on Rails. I specialize in crafting clean, scalable, and high-performance systems—whether it's a RESTful backend, interactive frontends, or full-featured web platforms.
Beyond the web, I also develop desktop applications using C++, Rust, Python, and JavaScript, adapting to different tech stacks based on project needs. On the scripting side, I write efficient Python scripts for automation, data processing, and task handling.
🎮 Passionate about game dev, I build 2D games using Python (Pygame, Arcade) focusing on smooth gameplay, custom assets, and performance optimization.
Whether you're building a startup MVP, automating internal tools, or designing a cross-platform game or app—I'm here to help bring it to life.
