About Me

I'm a senior software engineer with over 20 years of hands-on experience building web and mobile applications that real businesses depend on every day. My work has largely focused on PHP, Laravel, CodeIgniter, MySQL, API-driven systems, and complex, data-heavy platforms, where I've spent years designing and maintaining secure, high-performance backends for business-critical workflows. I've been involved across the full lifecycle-from early architecture decisions to long-term scaling and production support.

Over the last few years, my focus has expanded into mobile app development and AI-powered systems. This includes practical work with document intelligence, LLM-based automation, and human-in-the-loop workflows, always with an emphasis on reliability, clarity, and real-world usability rather than experimentation for its own sake. At the core, I enjoy solving real problems, shipping systems that hold up in production, and helping bridge the gap between traditional software engineering principles and modern AI-driven applications.

Experience Highlights

AI-Driven Automation & Document Intelligence

Hands-on experience building AI-powered workflows including OCR pipelines, document extraction, LLM-based Q&A systems, and automation with human-in-the-loop fallback for reliability and compliance.

Backend & System Engineering

Over 20 years of experience designing and maintaining backend systems using PHP, Laravel, and MySQL. Specialized in building API-first platforms, secure authentication flows, RBAC systems, and performance-optimized services that support real business operations.

Integrations & Payment Systems

Extensive work with third-party integrations including payment gateways, webhook-based systems, external APIs, and messaging platforms — built with security, observability, and failure handling in mind.

Legacy Systems & Scalability

Proven ability to refactor and modernize large legacy codebases, improve maintainability, introduce architectural discipline, and scale systems without disrupting existing business workflows.
