Mian Asif Faheem

Hi - I'm Mian Asif Faheem, a senior full-stack engineer and founder of MAAF Studio's. I build, debug, and lead complex production web systems - and I own the entire stack: database schema, server actions, API design, frontend UI, observability, and cloud infrastructure.

With over 8 years+ of hands-on experience - currently as a Senior Full-Stack Engineer at Vertex Data Consulting, and before that as an independent developer for clients worldwide - I've shipped SaaS marketplaces, an AI website builder, learning platforms, and high-variation WooCommerce stores.

I work best in async-first, high-ownership environments. I find and fix critical production issues before anyone assigns them, trace bugs across the stack - frontend, database, auth, infra - and build with an AI-native workflow using Claude Code and Cursor.

01 TypeScript, React & Next.js — from server actions to polished UI
02 Node.js, NestJS & PHP backends with clean REST API design
03 PostgreSQL, Supabase & MySQL schema design and query optimization
04 Stripe payments plus NextAuth, Clerk & JWT authentication
05 Playwright E2E testing, CI/CD pipelines, Vercel & VPS deploys
06 WordPress & WooCommerce plugins, Ionic cross-platform apps
07 Production incident ownership & cross-stack debugging

// Case Studies

Problems I've solved.

Real production issues - traced to the root cause and fixed for good.

Routeless Go

The silent login failure

Problem
Users were failing to log in with no error shown — sessions simply never stuck.
Root cause
Middleware was calling a NextAuth v4 API that is incompatible with v5's cookie format and JWT salt.
Fix
Decoded the JWT directly using the correct v5 cookie name, restoring login and sessions.
Next.js NextAuth v5 JWT
Heads & Tails Jewellery

Four plugins fighting over one cart

Problem
Cart totals were wrong and the checkout could recurse infinitely.
Root cause
Four competing plugins were all hooking woocommerce_before_calculate_totals and overwriting each other.
Fix
Consolidated them into one unified price calculator, fixing the recursion and the incorrect pricing.
WooCommerce PHP Hooks
WordPress · Stripe

Subscriptions that never saved

Problem
A Stripe webhook was silently failing to insert subscription data.
Root cause
The REST route was missing the permission_callback that WordPress has required since 5.5.
Fix
Identified and added the missing callback — found and fixed with no external guidance.
Stripe Webhooks WordPress REST
Rental Marketplace SaaS

Search that returned nothing

Problem
Marketplace search was coming back empty for real listings.
Root cause
A broken search filter pipeline, unstable useEffect dependencies, and a listing address serialization bug.
Fix
Fixed each layer and authored DB migrations to unblock results — one of 5+ critical bugs fixed without being assigned.
React 19 NestJS PostgreSQL
Rental Marketplace SaaS

Flaky E2E, fragile CI

Problem
End-to-end tests were flaky and CI was unreliable, so deploys could not be trusted.
Root cause
Playwright/Jest version conflicts, a missing JSDOM fetch polyfill, mixed E2E and unit runs, and flaky per-test session setup.
Fix
Pre-authenticated storage states, segregated suites, and Vercel deploys gated on green — enabling parallel cross-browser CI.
Playwright CI/CD Vercel
Heads & Tails Jewellery

Thousands of variations, slow pages

Problem
Product pages with engraving and personalisation options were slow to load.
Root cause
The original page architecture could not handle thousands of product variations efficiently.
Fix
Redesigned the flow to an AJAX + static-JSON architecture, eliminating the page-load bottleneck.
