Full Stack SaaS Developer | Backend-Focused Node.js, PostgreSQL, Strip
Are you building a SaaS product that works, but the backend is starting to feel risky?
Slow APIs, messy database queries, Stripe webhook issues, weak edge-case handling, unstable AWS flows, or features that keep breaking when new changes are added these are the problems I help fix.
I’m a backend-focused Full Stack SaaS Developer with nearly 5 years of experience building and revamping production-ready web applications. I work mainly with Node.js, NestJS, Express, PostgreSQL, MongoDB, MySQL, Redis, Queues, Stripe, AWS, Docker, REST APIs, and React/Next.js.
My strongest area is the part many projects underestimate: backend architecture, payment flows, database design, API reliability, background jobs, and production edge cases.
What I can help with:
• Full-stack SaaS development with React, Next.js, Node.js, and PostgreSQL or MongoDB
• Backend architecture using Node.js, NestJS, Express, REST APIs, and microservices
• Stripe subscriptions, webhooks, customer portals, retries, and idempotent payment flows
• PostgreSQL, MongoDB, and MySQL schema design, query tuning, and optimization
• Redis caching, queues, background jobs, and async workflows
• AWS serverless systems using Lambda, SQS, EventBridge, SES, S3, API Gateway, and CloudWatch
• MVP backend revamps, production-readiness audits, and system cleanup
Project highlights:
• Automated slide, image, and PDF generation platform with serverless background processing
• Canva-style React editor with export to JPEG, PNG, PDF, and Word
• Multi-role SaaS platform with RBAC, RFQ workflows, real-time notifications, and async mail pipelines
• Stripe subscription billing with webhook retry logic for a live B2B SaaS product
• 20+ applications delivered with strong client satisfaction
If your SaaS product needs a developer who can handle the frontend but thinks deeply about the backend, database, payments, and production reliability, send me a message. I’ll review your situation and tell you clearly how I Contribute.
