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.
