Elite Software Architecture & AI Engineering for High-Growth US Founders
Stop burning runway on $250/hour agency invoices that deliver junior code and endless communication delays. I partner directly with US tech founders, DTC brands, and venture-backed scale-ups to architect fast Next.js applications, high-converting Shopify storefronts, and automated cloud backends on AWS us-east-1 — shipping real, clickable progress every single week under fixed USD milestone pricing.
Who I build for and what I can build
Purpose-built web applications, fast Shopify stores, and reliable tools for US companies.
Your store is bleeding paid traffic because product pages load sluggishly on mobile phones. I audit your theme, strip out fighting apps, code custom lightweight sections, and build a checkout flow where shoppers actually buy.
You have a tight runway and need a functional MVP in weeks, not quarters, to win pilots or raise funds. I architect the core application, wire up Stripe subscription billing, and write clean, documented code you won't have to scrap later.
Law practices, medical clinics, and real estate teams with outdated sites that look broken on mobile devices. I build modern lead-capture funnels and automated booking flows that deposit qualified inquiries directly into your inbox.

Why US founders work with me
Direct engineer access, milestone-based pricing in USD, and working code delivered every week.
Most founders face one of two common challenges: either an agency quoted $30,000, presented senior executives in the pitch, and handed the project to junior interns, or an unvetted freelancer vanished before completion. I eliminate that uncertainty. Every engagement is scoped clearly, broken into transparent milestones with guaranteed fixed USD pricing, and backed by testable, production-ready code delivered every week.
I work in tight synchronization with United States business hours across Eastern, Central, and Pacific time zones. Communicating directly over Slack and video, you get senior engineering momentum without agency bureaucracy. You review working staging environments, align on sprint priorities during your standard working day, and launch continuous production features on schedule.
Collaborate directly with Mr Umer Malik from initial blueprint to final deployment. No account managers, no junior delegation, and no lost context.
Transparent quotes agreed upfront in USD ($) with fixed deliverables. Zero surprise invoices, zero ambiguous retainers, and zero hidden fees.
Complete ownership of your source code, database architectures, and keys transferred under signed Delaware mutual confidentiality upon milestone settlement.
Test real, interactive features every week on private staging environments. Continuous sprint updates keep you in full control throughout the build.
