Iβm a software developer with a strong passion for building reliable, scalable, and secure server-side systems. I focus on how data moves through an application β from APIs to databases β and I enjoy designing backend architectures that are clean, predictable, and efficient.
My journey started with curiosity about how web applications actually βwork behind the scenes.β Over time, I became deeply interested in Node.js, Express, and PostgreSQL, learning how to build powerful APIs and manage complex data flows.
I work extensively with Prisma ORM, and Iβve learned how to structure models, handle atomic transactions, and manage decimal precision for financial systems. I also use Redis for caching and performance optimization when dealing with frequent data requests.
Some of the projects Iβve built include:
PayFlow β a transaction system that handles atomic money transfers, wallet balance validation, and transaction history tracking using Prisma and PostgreSQL.
MindLab Backend β an API for lesson management and student progress tracking, with secure authentication and data validation middleware.
SkillForge Platform β a multi-role backend system built with Node.js, Express, and Redis caching for speed and scalability.
I take backend development seriously because I believe the server is the heart of every digital product. Iβm constantly improving my understanding of system design, microservices, and database optimization, aiming to build backends that donβt just work β but work fast, reliably, and securely.

π― My Focus
Iβm currently focused on mastering backend engineering β from database architecture and security to scaling APIs for production-level use. My goal is to become a backend systems engineer capable of designing infrastructure that supports millions of users smoothly.
I love solving hard backend problems, optimizing performance, and building APIs that empower frontends to shine. Every project I work on is another step toward becoming the kind of developer who builds trustworthy, high-performance systems that last.
Hey there, I am a seasoned software developer focused at building scalable softwares that solves real problems.
