About me
Intro
I build backend systems that keep Fortune 500 platforms running at scale — 10,000+ transactions a day at 99.9% uptime across retail, finance, and healthcare. Lately I've moved into something rarer: building AI agents that turn months of manual engineering into autonomous, governed workflows. Over 4+ years at Confiz, I've designed and shipped cloud-native microservices in ASP.NET Core/.NET and Java (Spring Boot) on Microsoft Azure — powering payments, order management, tax compliance, and pharmacy operations for global clients. A few results: - Architected an AI-driven API migration platform on Azure OpenAI that automated 400+ legacy transformations and cut manual effort by 70% - Built an enterprise e-invoicing and tax-compliance platform processing 1,000+ daily B2B/B2C invoices, reducing regulatory issues by 85% - Delivered a multi-tenant API ecosystem on Azure Functions + AKS at 99.8% uptime across 10+ integrations - Cut deployment time by 50% with CI/CD on Azure DevOps, Docker, Kubernetes, and Terraform; reduced downtime by 20% via SQL Server tuning and Redis caching I'm now focused on applied AI: building intelligent agents with Azure OpenAI and frontier tooling (including Claude and Cursor) for multi-step pipelines that handle process extraction, code generation, and validation — plus the governance and structured prompts that keep them aligned with security and architectural standards. This is exactly the software-engineering-meets-AI work European teams are hiring for now. Core stack: ASP.NET Core/.NET, C#, Java/Spring Boot, Azure (AKS, Functions, Service Bus), Kubernetes, Docker, Terraform, microservices, distributed systems, Clean Architecture/SOLID, REST APIs, SQL Server/Redis, React.js. Agile/Scrum, code reviews, and mentoring junior engineers. How I work: I've delivered for international clients across the Middle East and Europe, collaborating across time zones via Git, Azure DevOps, and async code review. I communicate fluently in English with both technical and non-technical stakeholders, and own my work independently in a distributed team. If you're building something ambitious in cloud-native backend, platform engineering, or applied AI and need an engineer who delivers at scale — let's talk. 📍 Based in Pakistan (GMT+5) 🌍 Open to: Remote in UK/EU time zones (preferred) · Relocation with visa sponsorship across the UK & the EU 💼 Full-time or contract 📩 [email protected]
