I help startups, SaaS companies, and enterprise teams build and scale reliable web applications, internal platforms, and AI-powered products using React, Node.js, and .NET.
With 9+ years of experience in full-stack development, I’ve worked with founders, growing businesses, and enterprise teams to build products that solve real business problems - not just ship code. My focus is on building systems that are stable, easy to maintain, and ready to scale as product complexity grows.
Over the years, I’ve helped clients:
✅ Build SaaS platforms with dashboards, subscriptions, analytics, and user role management
✅ Modernize legacy systems and migrate old architectures to scalable modern stacks
✅ Develop enterprise applications including CRM, ERP, workflow automation, and internal tools
✅ Improve frontend performance and user experience across complex web applications
✅ Integrate AI-powered features such as OpenAI workflows, chat assistants, and automation tools
My core expertise includes:
Frontend
• React.js
• Angular / AngularJS
• Next.js
• TypeScript / JavaScript
• Responsive dashboards and admin portals
Backend
• Node.js
• .NET Core / ASP.NET MVC
• C#
• REST APIs / Microservices
• Authentication (JWT, OAuth, SSO)
Database & Cloud
• PostgreSQL
• MySQL
• MongoDB
• AWS / Azure
• Docker / CI-CD
AI & Automation
• OpenAI API
• GPT-based features
• AI chatbots
• Workflow automation
• Data processing pipelines
Industries I’ve worked in:
SaaS • Healthcare • FinTech • eCommerce • Education • Enterprise B2B • AI Startups
Some notable work includes:
• Enterprise workflow systems for Microsoft-related projects using .NET and SharePoint
• Engagifii – Full stack SaaS platform built using Angular and .NET Core
• Large-scale web platforms using React, Node.js, and cloud infrastructure
• AI-integrated products with automation and intelligent workflow features
What clients appreciate about working with me:
✔ Clear communication
✔ Strong technical ownership

✔ Reliable long-term collaboration
