Case Studies

Work That
Shipped & Held.

I have spent a decade building SaaS platforms, payment infrastructure, and real-time systems that handle concurrent load without choking. These are not demos. Every project here survived real traffic, real users, and at least one 3am incident that taught me something I could not have learned otherwise.

Featured case studies: Corely (creator monetization with Stripe Connect splits), Kodezi (AI-powered IDE with sub-200ms inference routing), We Are The They (membership gating and event ticketing), Proetutor (LMS with async video and progress tracking), Syncro (multi-creator marketplace with payout reconciliation), WATT Community (real-time social platform on WebSocket at scale).

Corely

Creator Monetization Platform — Stripe Connect, Subscription Billing & Automated Payout System

Shipped a production-ready platform with fully automated financial operations. No manual payout processing. No reconciliation spreadsheets. The 2% fee model generates platform revenue that scales with creator volume without adding operational overhead — which is the only fee model that makes sense at scale.

Most creator monetization tools are either too simplistic (basic payment links with no subscription logic) or too complex (full marketplaces with infrastructure the creator doesn't need). Corely sits in the right place: one creator, one profile, direct audience payments, automatic payouts. The engineering challenge was building a Stripe Connect integration that handles the full financial lifecycle — onboarding, KYC handoff, subscription management, payout routing, and the 2% platform commission — without exposing the creator to any of that complexity on the frontend.

Kodezi

AI-Powered Web IDE & Developer SaaS — 200K Users, Product Hunt Launch of the Month, v1 through v4

200K active users. Product Hunt Launch of the Month (February 2023), Launch of the Week, and two Launch of the Day awards. The platform scaled from a single-developer MVP to a multi-version SaaS with real-time AI, gated premium features, in-editor tooling, and fully automated infrastructure monitoring — without requiring a rewrite of the core architecture between versions.

Kodezi is not a thin wrapper around an LLM API. It's a full in-browser IDE — Monaco Editor with multi-tab state, diff views, codebase-aware context — with OpenAI integration that understands your actual project, not just the snippet you paste in. I built it from v1 through v4: the initial MVP, KodeziChat with real-time Socket.io streaming, a credits-gated subscription system enforced at the API level, a VS Code extension with native-feeling Webview UI, and separately, an automated system status tracker that replaced manual monitoring entirely. The 200K user milestone and Product Hunt Launch of the Month were outcomes of getting the product architecture right across four iterative versions.

We Are The They

Membership Platform & Application Funnel — Stripe Subscriptions, ActiveCampaign Automation & Premium Event Listings

Delivered a platform that automated the entire membership pipeline — questionnaire submission to payment to welcome email — while maintaining the selective application process that makes the WATT membership valuable. The team reviews applications in their CRM; everything else runs without manual intervention.

The problem with most membership platforms is that they're built for open signups. Jimmy Rex needed the opposite: a selective application process where only approved members reach the payment page. That required a custom pipeline — not a tool, a system. Questionnaire submission feeds ActiveCampaign, the team reviews applications in their CRM, approved applicants get a Stripe checkout link, payment confirmation triggers AWS SES email delivery. Every step automated. No spreadsheets, no manual Stripe links sent over email.

Proetutor

High-Performance LMS Rebuild — 97 Lighthouse Score, Secure HLS Video Streaming & Subscription Monetization

97 Lighthouse performance score. 92 SEO score. 96 Best Practices. Legacy Core Web Vitals issues resolved — LCP and CLS both within acceptable ranges. Premium video content protected behind HLS signed URL delivery. The platform now has the SEO foundation to actually rank for the course topics it teaches.

Legacy Laravel and Bootstrap 3 systems age poorly. Slow Time to First Byte, failing Core Web Vitals, no protection on video URLs — Proetutor v1 had all of them. The rebuild wasn't just a UI refresh. It was a full architecture change: Next.js 15 with server-side rendering for SEO-indexed course pages, a clean Lumen v11 API layer, Bunny Stream replacing unprotected video hosting, and a monetization system that handles subscriptions and lifetime access from the same checkout. The result was a 97 performance score and a platform that ranks on the pages a legacy system never could.

Syncro

Multi-Creator Marketplace Platform — Stripe Connect, Subscription Monetization & Automated Payout Infrastructure

A production marketplace with fully automated financial operations across all creator accounts. Zero manual reconciliation. Zero manual payout processing. The commission model generates platform revenue at transaction capture, which means it scales with marketplace volume without adding operational overhead.

Single-creator platforms like Corely are architecturally simple compared to a marketplace. When multiple creators coexist on one platform — each with their own subscribers, their own Stripe connected accounts, their own payout schedules — the payment routing becomes the engineering problem. Syncro's architecture handles it: Stripe Connect multi-party routing, per-creator subscription lifecycle management, platform commission applied at payment capture, and isolated failure handling per creator account. One creator's payout failure doesn't affect any other creator on the platform.

WATT Community Platform

Private Real-Time Social Community — Rich Post Feed, Group Chat, iOS App & Admin-Managed Training System

A production-ready cross-platform community app that replaced fragmented third-party tools with a single owned platform. Real-time interaction across web and iOS simultaneously. Training content delivered through a structured admin-managed system, not a shared folder link. All platform features gated to verified paid members — no workarounds, no shared URLs that grant access.

Private community platforms fail in one of two ways: they either use off-the-shelf tools that don't integrate cleanly and feel cobbled together, or they get built as a real-time system that's underengineered and breaks under concurrent load. WATT Community needed to be a first-class product — not a Facebook Group with a custom header. Rich media posts with real-time updates across web and iOS simultaneously, group chat with full member management, a structured training system with protected Wistia video, and RBAC that means non-paying members genuinely can't access anything. All of it on a single Socket.io event layer shared between the Next.js web app and the React Native iOS app.

SaaS Development

This was the first time I used Fiverr to build a dashboard and Assad Ullah exceeded my expectations. Not only did I get a robust site but the level of design went beyond cookie cutter to something that feels premium and customized!

Your system has a ceiling. I find it before your users do.

If you are building a payment platform, a multi-tenant SaaS, or a real-time product that needs to handle concurrent load without a queue backup or a Stripe webhook retry storm — let's talk architecture before you write another line of code.
