Contract Developer for US SaaS Teams

STRIPE.
React.
AWS.
BUILT
PROPERLY.

I build payment infrastructure and SaaS products for US founders. Stripe billing, PCI-compliant systems, full-stack dashboards built on contract. No overhead, no long-term commitment. I manage my own sprints so you can stay focused on your product.

What I Build

Three areas where I go deep. Not a generalist who dabbles in everything.

01 — Payment Systems

Stripe Billing & Infrastructure

I handle subscription management, metered billing, usage-based pricing, dunning flows, failed payment recovery, customer portals, and webhook architecture. Everything is built to hold up as your user base grows.

02 — Compliance & Security

PCI Systems & AWS Deployment

I work with VGS tokenization, PCI Vault integration, and compliant card data flows. I also handle AWS infrastructure so your product ships secure and production-ready from the start.

03 — SaaS Products

Full-Stack Dashboards & APIs

React and Vue frontends paired with Node.js or Laravel backends. Multi-tenant architecture, role-based access control, third-party integrations, and REST APIs written in a way your team can actually work with long term.

Selected Work

Real projects with real outcomes. Every engagement below started from a cold introduction.

01

SaaS / FinTech · Austin, TX · 2024

Usage-Based Billing System

A B2B SaaS team was manually sending invoices every single month. I built them a Stripe metered billing system with usage tracking, automated invoicing, a customer portal, and a dunning flow for failed payments. Deployed on AWS. Fully automated in four weeks.

Healthcare SaaS · Remote US Team · 2024

PCI-Compliant Payment Vault

A healthcare startup needed to process card data without storing raw PAN data on their servers. I implemented VGS tokenization on top of their existing Laravel backend and deployed everything on AWS. They passed their PCI SAQ-A audit on the first try.

Digital Agency White-label · Chicago, IL · 2023

Multi-Tenant SaaS Dashboard

A 7-person agency in Chicago needed contract overflow for an enterprise client project. I built a multi-tenant Vue.js dashboard with role-based access control and a Laravel API, tracked in Jira and managed through Bitbucket. Their team took full ownership from day one with complete documentation.

Proof Over
Promises.

One real verified review is worth more than ten polished ones. More US client reviews coming as I build out my client base.

★★★★★

Irfan quickly implemented the given PHP task and perfectly adjusted to our development workflow with Docker and GitHub Pull Requests.

Code Quality

Every project I ship comes with clean, documented, maintainable code. Full handoff documentation and a Loom walkthrough are always included. You can browse my public work on GitHub directly.

First Engagement Offer

I am actively building my US client base. If you have a Stripe integration, SaaS dashboard, or Laravel API project, I am offering reduced rates on the first engagement in exchange for a detailed review. One or two spots open this month.

How I Work

Simple process, no surprises. You will always know what is happening and what comes next.

Step 01

15-Min Discovery

I ask the questions most developers skip. We figure out if there is a real fit before either of us commits to anything.

Step 02

Fixed-Price Proposal

You get a clear scope, timeline, and fixed price. Not an hourly rate with a rough estimate attached. No surprise invoices at the end of the month.

Step 03

Self-Managed Sprints

I send daily Slack updates and do weekly video check-ins. I run the sprint myself so you can see progress in real time without having to manage me.

Step 04

Clean Handoff

You get full documentation, commented code, and a Loom walkthrough. Your team can pick it up and maintain it without needing me on a call.

Who I work
best with.

I take on a limited number of projects at a time. The right fit means better work and a smoother experience for both of us. If the left column sounds like you, reach out.

Good fit →

  • US SaaS founder or technical co-founder
  • Project involves payments, billing, or compliance
  • You need contract work, not a full-time hire
  • Communication and follow-through matter to you
  • Agency with overflow React or Laravel projects
  • You have a defined scope and a realistic budget

Not a fit ×

  • Price is the only thing that matters
  • No defined scope or timeline going in
  • Equity-only or no-pay arrangements
  • You need a project manager more than a developer
  • On-site presence in the US is required
