A high-performance full-stack eCommerce ecosystem engineered for a luxury perfumery. Developed with Next.js (App Router) on the frontend and Spring Boot (Kotlin) on the backend, it features a distributed architecture supporting multi-region localization, real-time dynamic currency conversion, an advanced custom rich-text parser, and a secure role-based access control system.
Projects/Tomorrow's Cuisine App
- Personal Project
- Duration: Jul 24’ — Present
- Reading Time: ~2 min read
A high-performance modular Android ecosystem combining social networking with intelligent recipe discovery. Built with a multi-module architecture to optimize build times and ensure strict feature isolation. The backend leverages Ktor's asynchronous engine and PostgreSQL for a high-concurrency, localized content delivery system.
Projects/Call Blaze App
- Personal Project
- Duration: May 25’ — Jun 25’
- Reading Time: ~2 min read
A specialized systems-level Android application for automated telephony handling. It utilizes root-level ALSA (Advanced Linux Sound Architecture) integration to bypass OS restrictions, enabling direct audio injection into the voice stream. This project required a deep understanding of the Linux sound subsystem and Android's internal telephony services.
Projects/Solar Monitoring App
- Company: Zarin Electronic — Contract Android Developer
- Duration: May 25’ — Jun 25’
- Reading Time: ~2 min read
A high-fidelity industrial monitoring application for real-time renewable energy telemetry. It leverages custom Canvas rendering for sub-millisecond data visualization and a robust BLE (Bluetooth Low Energy) stack to handle high-frequency inverter updates without packet loss. Built on a Clean MVVM architecture for maximum reliability in mission-critical field environments.

About — My Journey So Far
I started with native Android engineering — mastering clean architecture, dependency injection, and reactive state management with Kotlin Coroutines and Jetpack Compose.
To deliver end-to-end solutions, I expanded into backend systems (Spring Boot, Ktor, Node.js) and modern frontend engineering (Next.js, React, SCSS). Today I ship full-stack products from architecture to production deployment — with a bias toward performance, type-safety, and maintainability.
