NestJS developer for Budgetting App
Zeeshan has been absoltey vital in making our project successul. He works incredibly hard, he's committed, efficient and gives everything to make a project a success. He's worked with us for 9 months to build an extremely complex app, and for a next app he's the fist person I would bring on board again.

I work with founders, startups, and growing companies that need more than just a developer - they need someone who can understand the product, make sound technical decisions, and build systems that are scalable, maintainable, and ready for growth.
Whether you're launching a new SaaS product, building an MVP, expanding an existing platform, creating customer portals, developing APIs, implementing subscription systems, or integrating AI capabilities, I focus on delivering solutions that create long-term value rather than short-term fixes.
My expertise spans the entire development lifecycle, from architecture planning and database design to frontend development, backend systems, cloud infrastructure, deployment, and ongoing product improvements.
Over the years, I've built and contributed to:
• SaaS Platforms & Startup MVPs
• Multi-Tenant Applications
• Customer Portals & Admin Dashboards
• Internal Business Tools
• Subscription & Billing Systems
• API-Driven Applications
• AI-Powered Products & OpenAI Integrations
• Automation Platforms & Workflow Systems
• Cloud-Native Web Applications
Tech Stack:
Frontend: Next.js, React, TypeScript, JavaScript, Tailwind CSS, Material UI
Backend: Node.js, NestJS, Express.js, REST APIs, GraphQL, WebSockets
Databases: PostgreSQL, MongoDB, MySQL, Redis, DynamoDB
Cloud & DevOps: AWS, Lambda, EC2, S3, RDS, CloudFront, Docker, CI/CD, Vercel
AI & Automation: OpenAI, ChatGPT Integrations, AI Workflows, Automation Systems
I enjoy working on products where technology directly supports business growth, user experience, and operational efficiency.
