Job Success
Multan, Pakistan - 1:34 pm local time
Full stack developer, 4+ years, MERN-primary. I specialize in the layer most developers underestimate: AWS serverless infrastructure, production APIs, and payment systems that handle edge cases instead of breaking on them.
━━ What I Build ━━
Full Stack
→ React · Next.js · Node.js · Express · MongoDB · PostgreSQL
Backend & APIs
→ Node.js / Express (primary) · Python: FastAPI · Django REST · Flask
→ GraphQL · JWT · OAuth2 · Cognito · Clerk
Payment Infrastructure
→ Stripe: subscriptions, metered billing, webhooks, retry logic, customer portal
→ Paddle: checkout and VAT flows
→ Idempotent flows — no double charges, no silent failures
AWS Serverless
→ Lambda · EventBridge · SQS · API Gateway · SES · S3
→ CloudFront · Cognito · App Runner · Route 53 · CloudWatch
━━ Shipped ━━
✦ Automated slide & PDF generation platform — drag-and-drop canvas editor (built from scratch), daily Lambda + EventBridge pipeline that fetches third-party content, replaces dynamic elements while preserving the design, generates images and PDFs via Puppeteer and Sharp, then distributes via SES email and to TV screens and Amazon Echo Show devices. Zero manual intervention.
✦ Canvas-based design tool — Canva-style editor in React where users drag, resize, and style elements, with serverless export to JPEG, PNG, PDF, and Word.
✦ Multi-role SaaS platform — full RBAC (Admin / Client / Contractor), RFQ workflow, real-time FCM notifications, and an async SQS + Lambda + SES notification pipeline that never blocks the main application thread.
✦ Stripe subscription billing with webhook retry logic — B2B SaaS, live production.
✦ 20+ applications delivered — 100% client satisfaction.
━━ Right Fit If You Need ━━
✔ MERN or Node.js application built from scratch
✔ Complex AWS serverless architecture (Lambda, EventBridge, SQS, SES)
✔ Stripe or Paddle integration done properly — not just the happy path
✔ Document, image, or PDF generation pipeline
✔ Multi-role RBAC/ABAC system with real-time notifications
✔ Python FastAPI or Django REST API
Fast responses. Clean code. Message me — I'll tell you in 10 minutes if I can help.
