You will get a stabilized SaaS App with Node.js, PostgreSQL & Deployment Fixes
Project details
You will get your existing SaaS or web application stabilized by fixing backend issues, slow PostgreSQL queries, broken APIs, authentication problems, Docker/CI-CD issues, environment errors, or failed deployments.
I have 10+ years of experience working on production web applications, SaaS platforms, dashboards, APIs, and database-heavy systems. My focus is not just applying temporary patches. I review the issue, identify the root cause, fix the affected area, test the workflow, and provide clear handover notes so you understand what changed.
This project is ideal if your app is already built but something is blocking production use: failed deployment, unstable backend, broken user flow, slow reports, API errors, database performance issues, login/auth problems, or infrastructure misconfiguration.
Depending on the package, I can fix a small isolated issue, stabilize one major SaaS workflow, or perform a deeper production recovery covering code, database, deployment, Docker, CI/CD, environment setup, and handover.
The goal is simple: get your application stable, usable, and ready for production without introducing messy quick fixes or unnecessary rewrites.

Remaining work on Android project
Pujan is an excellent resource. My project got delayed for several reasons beyond my control, and Pujan was accommodating enough. Great quality of work and responsive. I highly recommend him for any Android related work!

🎯 HOW I CAN HELP YOU
SAAS MVP DEVELOPMENT
Turn your idea, prototype, or early product into a production-ready SaaS that can launch, onboard users, and support real business growth. I’ve built multi-tenant platforms, RBAC systems, subscription workflows, and admin dashboards that improved performance by 30% and reduced deployment issues through cleaner architecture and CI/CD.
BACKEND ARCHITECTURE AND API DEVELOPMENT
Increase system stability and speed with backend foundations that support complex workflows, clean data handling, and future scaling. My experience includes Node.js, NestJS, PostgreSQL, Prisma, Supabase, REST APIs, webhooks, background jobs, and database-driven systems across production SaaS products.
THIRD-PARTY API INTEGRATIONS
Connect your app to payment, CRM, accounting, AI, and external platform APIs without breaking user experience or reliability. I’ve handled OAuth, token refresh, rate limits, retries, pagination, and webhook logic in systems like HMRC-integrated tax SaaS and other production business applications.
PRODUCTION SYSTEM OWNERSHIP
Protect your application with stronger authentication, authorization, security checks, logging, backups, and maintainable system design. I bring 11+ years of end-to-end ownership across CTO, backend, and full-stack roles, with hands-on experience making decisions around architecture, deployment, and long-term maintainability.
INFRASTRUCTURE AND DEPLOYMENT
Accelerate releases and reduce production friction with deployment setups that fit your product and team. I’ve worked with AWS, Vercel, Docker, GitHub Actions, Coolify, VPS/server management, and migration from managed platforms for SaaS and business-critical applications.

I typically respond within 4 hours and can support urgent projects when needed.
𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸
I build SaaS backends in Node.js and Next.js, with TypeScript and PostgreSQL keeping the codebase and data model clean. I use NestJS, Prisma, and Supabase to ship secure APIs and authentication, while Docker and AWS help me deploy reliably. GitHub Actions supports my CI/CD, and I use Redis to keep performance steady as products scale.
I build SaaS products with Next.js and Node.js, shape API integration flows, and harden PostgreSQL-backed systems with Docker and CI/CD.
