Lead Software Engineer | 19+ Years of Architecture & Full-Stack Delivery Who I Am I am a Lead Software Engineer and Technical Architect based in Karachi, with nearly two decades of experience building high-stakes enterprise applications. My career has been defined by a simple philosophy: I don’t just write code that works; I architect systems that scale, endure, and drive business value. From leading teams at Royal Cyber Inc. to delivering sole end-to-end products, I bridge the gap between complex business requirements and hardened technical reality. What I Have Done I specialize in the .NET and PHP ecosystems, with a heavy focus on deep-level integrations and SaaS architecture. My track record includes: Enterprise Middleware: I designed and delivered a global biometric integration engine that automated attendance for thousands of users, reducing manual HR effort by 60%. SaaS & EdTech: I built and shipped Teknowland, a STEM e-learning platform serving thousands of external paying customers with a focus on high-concurrency and accessibility. Security & Identity: I have integrated complex SSO (SAML 2.0, OAuth 2.0, Azure AD) solutions for international organizations, ensuring enterprise-grade data protection. My Technical Toolkit Backend: .NET Core, C#, PHP, SQL Server (Advanced Query Optimization & Schema Design). Frontend: Modern JavaScript, jQuery, ASP.NET MVC, and a strict adherence to Core Web Vitals for performance. Infrastructure: CI/CD pipeline implementation (Azure DevOps/GitHub Actions), Automated Testing (xUnit/TDD), and IIS Server management. What Makes Me Stand Out While many developers can build a prototype, I specialize in “Architectural Hardening.” I bring a senior, forensic eye to every project especially when incorporating AI. I use AI to accelerate the “boring” boilerplate, but I apply 18 years of expertise to audit every line for security vulnerabilities, logical hallucinations, and performance bottlenecks. When you hire me, you aren’t just getting a coder; you are getting a Technical Lead who understands the full SDLC, prioritizes security, and takes total ownership of the final delivery.
