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!

About Pujan
Senior Backend Engineer | Node.js | TypeScript | PostgreSQL | AWS

Whether you're launching a SaaS MVP, scaling a growing product, rescuing an existing codebase, or replacing a developer who left, you need someone who can take ownership from architecture to production.
𝗧𝗵𝗮𝘁'𝘀 𝗲𝘅𝗮𝗰𝘁𝗹𝘆 𝘄𝗵𝗮𝘁 𝗜 𝗱𝗼. I help startups launch faster, reduce technical debt, improve backend performance, and build software that's ready to scale as the business grows.
For the past 𝟭𝟭+ 𝘆𝗲𝗮𝗿𝘀, I've been building and scaling production SaaS applications, designing backend architecture, optimizing databases, integrating external services, and deploying production-ready systems that businesses depend on every day.
When you hire me, you're not hiring another Node.js developer.
You're hiring someone who thinks like a technical partner.
Before I write a single line of code, I think about:
✔ Will this architecture still work two years from now?
✔ Will this database scale to millions of records?
✔ Will future developers understand this code?
✔ What happens when traffic increases?
✔ What security risks are we introducing?
✔ How can we reduce future maintenance costs?
Because solving those problems early saves you thousands later.

𝗥𝗲𝗰𝗲𝗻𝘁 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝘀 & 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀
I've helped startups and businesses build products across insurance, fintech, logistics, tax, analytics, and enterprise SaaS.
• Insurance management platforms with underwriting, claims, accounting, endorsements, audit trails, and complex financial workflows
• HMRC-integrated UK tax filing SaaS
• Multi-tenant developer platforms similar to Vercel
• Fleet management and GPS tracking systems
• Analytics dashboards and reporting platforms
• Internal business applications and workflow automation
Every system required scalable architecture, secure authentication, complex business rules, API integrations, and 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻-𝗿𝗲𝗮𝗱𝘆 𝗰𝗹𝗼𝘂𝗱 𝗶𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲.

Many developers can build features.
Far fewer can inherit an unfamiliar production system, identify architectural bottlenecks, optimize database performance, stabilize deployments, and make technical decisions that keep a product maintainable for years.
𝗧𝗵𝗮𝘁'𝘀 𝘄𝗵𝗲𝗿𝗲 𝗜 𝗮𝗱𝗱 𝘃𝗮𝗹𝘂𝗲.
I work comfortably as a solo engineer or alongside existing teams, communicate clearly, and take ownership of both technical decisions and delivery.

• Clean, maintainable code
• Clear communication
• Scalable architecture
• Secure backend systems
• Reliable API design
• Thoughtful technical decisions
• Production-ready deployments
• A long-term engineering mindset, not quick fixes
If you're looking for a backend engineer who can take ownership of your architecture, improve an existing system, or build a production-ready SaaS platform from the ground up, let's discuss your project.
