About Me

Meet Mubashir

I'm Mubashir, a Senior Product Engineer & Frontend Developer based in Lahore, Pakistan. I specialise in building scalable SaaS applications and high-performance B2B e-commerce platforms that serve international wholesale manufacturers.

Over 5+ years, I've engineered headless storefronts with Medusa.js and Next.js, architected Supabase-backed SaaS products, and built B2B wholesale catalog systems for Sialkot export manufacturers targeting EU and North American buyers.

How I Work

My Process

Every project follows a structured process — not a rigid one. I adapt the depth of each phase to fit the project scope, timeline, and team maturity.

01

Discover & Define

I start by understanding your users, business goals, and constraints — stakeholder interviews, competitive audits, user research, and defining the problem clearly before touching any UI.

02

UX Strategy & Design

From research insights, I build user flows, information architecture, wireframes, and interactive prototypes. Every decision ties back to user needs and business outcomes — not aesthetics alone.

03

High-Fidelity UI & Handoff

Polished, pixel-perfect UI in Figma — with a scalable design system, component documentation, and dev-ready specs. I stay involved through implementation to ensure quality.

Questions

Frequently Asked Questions

Primarily SaaS products, B2B dashboards, eCommerce apps, and marketing websites. I work best on projects where design directly impacts user retention or conversion — not just visual polish.

Yes — I take on select freelance and contract projects alongside my primary work. If you have a project in mind, reach out and we'll figure out if it's a good fit.

Yes, and I enjoy it. Early-stage work is where good UX strategy makes the biggest difference. I've helped startups define their product from scratch and avoid costly design mistakes early.

Everything delivered in Figma with named components, token-based styles, interactive prototypes, and annotated developer specs. I also offer implementation review to ensure design quality through development.

Absolutely. I've joined projects mid-stream and extended existing Figma design systems without breaking them. I can also audit and improve governance documentation.

I produce live websites via Webflow and Framer with production-ready output. I have working knowledge of HTML and CSS. I'm a designer first — my value is in the design layer.
