About Me
I am a Software Engineer with a focus on Backend Engineering, DevOps, and Solution Architecture.
My experience includes building backend services and RESTful APIs using Python, FastAPI, Flask, Laravel, and Odoo, as well as working with PostgreSQL, MySQL, Microsoft SQL Server, and MongoDB.
Beyond application development, I work across deployment and infrastructure using Docker, Nginx, CI/CD, Linux servers, and monitoring tools.
I have contributed to systems across several business domains including Fintech, eDeposito, Vendor Management, Order Tracking, Customer Service, and internal operational applications.
I enjoy understanding business requirements and translating them into technical solutions that are practical, maintainable, scalable, and reliable.

How I Approach Engineering
Understand Before Building
Start by understanding the business problem before choosing the technology.
Keep Architecture Practical
Good architecture should simplify a system, not make it unnecessarily complicated.
Build for Reliability
Software should not only work during development but remain dependable in production.
Think Beyond the Code
Backend systems also depend on databases, infrastructure, deployment, monitoring, and maintainability.
Technology Stack
The languages, tools, and disciplines I rely on to design and ship dependable systems.
