7+ Years Building Systems That Scale.
I am a software engineer with 7+ years building production systems end to end for businesses worldwide. My work covers backend architecture, REST API design, SaaS platform development, cloud deployment, and generative AI integrations including chatbots, document processing, and workflow automation. I work with SaaS companies, agencies, and businesses across the US, UK, Europe, and Australia.
I am framework-agnostic by choice. I select the right tool for each problem rather than forcing one stack onto every project. My focus is software that scales cleanly, automation that removes real manual effort, and AI integrations that deliver a measurable result rather than just a demo.
Every engagement runs on milestone billing and full source-code ownership. You know exactly what you are getting, what it costs, and when it ships.
Engineering Across the Full Stack.
Backend to AI Integration.
I design and build production-grade software end to end: backend systems, REST APIs, SaaS platforms, and generative AI integrations. Every system is built for real-world scale, maintainability, and a measurable outcome.
Generative AI Integration
Connect OpenAI, Claude, and other LLM providers to your existing systems. Build chatbots trained on your knowledge base, document processing pipelines, intelligent data extraction, and AI-powered features that deliver real business outcomes.
Workflow Automation
Eliminate manual, repetitive operations by connecting your tools and databases through intelligent automation pipelines. From simple triggers to multi-step agentic workflows that complete entire processes without human input.
Backend Systems & API Development
Production-grade backend architecture, RESTful API design, database engineering, authentication systems, and cloud deployment. Clean, documented code built to scale and maintain without bottlenecks.
SaaS Platform Development
Multi-tenant SaaS architecture, subscription billing, admin panels, role-based access, and Vue.js frontends. From MVP to production with full documentation and source-code ownership transferred on delivery.
Engineering Services That Move the Business Forward
Backend systems, APIs, SaaS platforms, generative AI integrations, and payment systems. Every engagement is fixed-price, milestone-billed, and scoped in writing before work begins.
Backend Development & System Architecture
Production-grade backend systems, database design, REST API architecture, cloud deployment, and security hardening. Built to scale, maintain, and extend without bottlenecks.
Generative AI Integration
OpenAI and Claude AI integrations, chatbots, document processing, and workflow automation wired into your existing stack. Every AI feature is built for a measurable business outcome rather than a proof of concept.
SaaS Platform Development
Multi-tenant SaaS architecture, subscription billing, admin panels, role-based access, and Vue.js frontends. From MVP to production: clean, documented, and maintainable.
Payment Systems & Subscription Billing
Stripe and PayPal integrations, subscription plans, webhook processing, failed payment recovery, invoice generation, and billing portals. Revenue flows reliably with no silent failures and no lost transactions.
API Integration Services
RESTful API architecture, third-party integrations, and seamless data synchronisation between your systems and any external platform. Every API delivered clean, versioned, and fully documented.
Project Rescue & System Recovery
Broken build? Developer gone? I audit the codebase, document every issue, and deliver a fixed-price recovery plan before a single line of code is changed. 40+ systems rescued and back online.
Written recovery plan before any work startsLive Projects. Real Results.
Production systems across SaaS, eCommerce, fundraising, and fleet management. Each delivered on scope with full documentation and code ownership.
Broken Payments. Missing Developer.

Client: Randy J. Verified Upwork Client
Previous developer vanished with 60% of the build done. Checkout was broken, payments were failing silently, Stripe webhooks were misconfigured, and there was zero documentation. Real orders were being lost every day the store stayed down.
Written code audit first, no code touched. I identified the Stripe webhook misconfiguration, the SQL injection vulnerabilities, and the broken order management panel within 48 hours. A fixed-price milestone plan was delivered before a single change was made. Randy had full staging access at every step.
- Stripe webhook endpoints rebuilt and verified, silent payment failures eliminated completely
- Payment flow tested end-to-end across all checkout paths before going live
- SQL injection and CSRF vulnerabilities patched across the entire codebase
- Admin reporting panel rebuilt with real-time order tracking and payment status
- Full codebase documented so Randy's team could maintain it independently
"Bilal was easy to work with and did a great job. Easy to communicate with and make adjustments to the project throughout in order to successfully complete the project for us."

Questions Worth Asking Before You Hire
Backend engineering, REST API development, SaaS platform architecture, cloud deployment, and generative AI integrations. 7+ years building production software end to end for businesses across the US, UK, Europe, and Australia.
Backend systems, REST and integration APIs, multi-tenant SaaS platforms, AI-powered applications, payment systems, and workflow automation. I am framework-agnostic and select the right stack for each problem.
Yes. Chatbots, document processing, data extraction, and AI-powered workflows can be added to existing backend systems or SaaS platforms without a full rebuild. I integrate with OpenAI, Claude, and other LLM providers.
Every project is fixed-price with a written scope and line-item quote delivered after a free discovery call. No hourly surprises. Cost depends on the scope and integrations required. Book a call for a precise estimate.
Yes. Full source code ownership transfers to you on final milestone payment. No vendor lock-in, no ongoing fees, and no dependency on my infrastructure. You can maintain or extend the system independently.
SaaS companies, e-commerce businesses, professional services, nonprofits, and any business that needs reliable production software or wants to automate operations with AI.
