🏆 Top Rated Plus | $90K+ Earned | 7,000+ Hours on Upwork | 100% Job Success I build and maintain full-stack web applications using MERN and MEAN, with a strong focus on React, Angular, Node.js, TypeScript, MongoDB, and API-driven architectures. With 9+ years in full-stack development, I’ve worked across SaaS, healthcare, enterprise, FinTech, eCommerce, and internal business platforms. A big part of my work involves taking an existing product or codebase, understanding how it works, fixing what’s holding it back, and adding new functionality without creating unnecessary complexity. What I work on ✅ MERN applications — React, Node.js, Express, MongoDB, TypeScript ✅ MEAN applications — Angular, Node.js, Express, MongoDB ✅ SaaS platforms, dashboards, admin panels, portals, and business applications ✅ Healthcare applications, patient portals, healthcare workflows, provider dashboards, and data-driven systems ✅ REST APIs, third-party integrations, authentication, role-based access, and business workflows ✅ Existing application modernization, feature development, bug fixing, and performance improvements ✅ AI integrations, OpenAI APIs, AI assistants, automation, and intelligent workflows ✅ Enterprise applications and internal tools with complex user roles and workflows Core Technologies Frontend React.js • Angular • Next.js • TypeScript • JavaScript • HTML5 • CSS3 • Tailwind CSS • Responsive UI Backend Node.js • Express.js • REST APIs • Microservices • .NET Core / ASP.NET • C# Databases MongoDB • PostgreSQL • MySQL • SQL Server Cloud & DevOps AWS • Azure • Docker • CI/CD • Git AI & Automation OpenAI API • GPT integrations • AI chatbots • Workflow automation • Data processing Healthcare Experience Healthcare is one of the areas I regularly work with, particularly where applications involve patient/provider workflows, dashboards, portals, scheduling, records, role-based access, reporting, integrations, and sensitive business data. I understand that healthcare applications need more than a good-looking interface. Permissions, data flow, reliability, auditability, integrations, and predictable workflows matter just as much as the frontend and backend implementation. Some of my work • Engagifii — Full-stack SaaS platform using Angular and .NET Core • Large-scale web platforms using React, Node.js, MongoDB/PostgreSQL, and cloud infrastructure • Enterprise workflow and business applications • Healthcare-oriented platforms involving dashboards, portals, workflows, and integrations • AI-enabled products with intelligent workflows and automation • Microsoft-related enterprise projects using .NET and SharePoint I’m comfortable joining an existing development team, taking ownership of a specific area, or handling a full feature from UI → API → database → deployment. If you’re looking for a senior developer for a MERN, MEAN, React, Angular, Node.js, or healthcare application, feel free to reach out.

If you're looking for a developer who can take your idea from a rough concept to a production-ready platform — without the back-and-forth, the delays, or the technical debt — you're in the right place. I'm a Full Stack Developer with 5+ years of hands-on experience building web applications, SaaS platforms, e-commerce systems, and AI-powered products for startups, growing businesses, and enterprise teams. I've delivered 25+ production-grade platforms across industries, and I bring the same level of ownership and clarity to every engagement — whether it's a focused MVP or a complex, multi-service architecture. My work sits at the intersection of clean engineering and real business outcomes. I don't just write code — I help you make the right technical decisions early, so you scale confidently later. What I Specialize In I work across the full stack, with deep expertise in: 🔹 Frontend: React, Next.js, Angular — responsive, component-driven UIs built for performance and maintainability 🔹Backend: Node.js, NestJS, Express, Python — scalable APIs, microservices, and event-driven systems 🔹Stack Focus: MEAN (MongoDB, Express, Angular, Node) and MERN (MongoDB, Express, React, Node) 🔹AI & LLM Integration: OpenAI, LangChain, RAG pipelines, AI-powered features embedded into real products 🔹Databases: PostgreSQL, MySQL, MongoDB, Redis 🔹Cloud & DevOps: AWS (EC2, S3, Lambda, RDS, CloudFront), Docker, CI/CD pipelines 🔹Security & APIs: JWT, OAuth2, RBAC, REST and GraphQL APIs, third-party integrations What I Build Startups & MVPs Fast, structured launches that don't create future problems. I help founders move from idea to working product quickly while keeping the architecture clean enough to grow into. SaaS & B2B Platforms Multi-tenant architectures, role-based access, admin dashboards, billing integrations, and the backend infrastructure that enterprise clients expect — built to handle real scale. E-Commerce Platforms Custom storefronts, product and inventory systems, payment gateway integrations, order management, and performance-optimized frontends that convert. AI & LLM Products I integrate AI meaningfully into applications — chatbots, document intelligence, semantic search, workflow automation, and custom LLM pipelines — not as a gimmick, but as a core product feature that adds real value. How I Work I ask the right questions before writing a single line of code. I flag risks early, communicate proactively, and treat your project with the same care I'd give my own. Clients across time zones consistently highlight that working with me feels smooth, predictable, and partnership-driven. Whether you need a full stack engineer to own the entire product, a React or Angular specialist for the frontend, a Node.js or Python developer on the backend, or an AI integration expert — I adapt to what your project actually needs.
