URGENT: DevOps / Full-Stack Developer needed to secure & stabilize live SaaS (immediate start)
Working with Zeeshan was a great experience from start to finish. He's a skilled programmer who clearly knows his craft , he understood exactly what I needed, communicated clearly throughout, and delivered clean, well-structured code on time. He was responsive to feedback and proactive about flagging potential issues before they became problems, which saved a lot of back-and-forth. On top of the technical quality, he's professional, reliable, and genuinely easy to work with. I'd happily hire him again and recommend him to anyone looking for a developer they can trust.

Urgent pre-launch review: Stripe webhooks + AI proxy security, finished Next.js/Supabase SaaS
Zeeshan built the landing page for my SaaS and I'm really happy with how it turned out. I came to him with an existing page I wasn't satisfied with, and he rebuilt it into something that actually looks premium, which is exactly what I was after.
What stood out most was how responsive he was. He applied my feedback fast, sometimes I'd look and he'd already made the changes before even messaging me. We went through a few rounds of revisions and he never made it feel like a hassle, he just kept improving it until it was right.
He also brought his own ideas to the table instead of just following instructions. A couple of his suggestions were better than what I had in mind, and I ended up using them. He clearly thinks about what actually converts, not just how things look.
He was fair on price, flexible on how he delivered the files, and made it clear he's there for support even after the work is done. I can genuinely see myself working with him again as my product grows. Highly recommend.

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.
