Show moreI’m a Full Stack Developer and Senior Software Engineer with 9+ years of experience building scalable, production-grade applications across frontend, backend, and cloud environments.
Over the years, I’ve worked extensively with Node.js, React, PHP, JavaScript/TypeScript, and Python — designing systems with a strong focus on performance, maintainability, reliability, and developer experience.
What drives me most is understanding how things work beneath the surface.
I enjoy exploring system design, application architecture, observability, error handling, AI systems, and the engineering decisions that shape scalable software. I’m especially interested in building applications that are not only functional, but thoughtfully engineered for long-term growth.
Beyond day-to-day engineering, I’m passionate about mentoring developers and sharing practical knowledge through technical writing, courses, and hands-on learning content. I enjoy breaking down complex topics into approachable, real-world explanations that help other developers grow with confidence.
Currently, I’m expanding deeper into AI engineering by building real-world agentic AI systems in public — focusing on production-grade architecture, tooling, RAG pipelines, guardrails, and scalable AI application design.
Core areas I enjoy working on:
• Backend Engineering & APIs
• Frontend Architecture & Performance
• System Design & Scalability
• Reliability, Observability & Error Handling
• AI Applications & Agentic Systems
• Clean Code & Engineering Best Practices
I believe great engineering comes from continuous learning, thoughtful problem-solving, and building with purpose. Show less
