I'm a Software Engineer focused on backend development and system architecture, with strong foundations in computing and low-level systems.

My background in Electrical Engineering (with emphasis on computing) shaped the way I approach software: understanding systems end-to-end — from hardware and networking layers to backend services running in production.

I enjoy building systems that are reliable, efficient and scalable, combining backend engineering with IoT and embedded systems.

Currently I work mainly with Python backend development, API design, database modeling, and containerized environments, while also developing firmware for ESP32-based IoT integrations.

My main interests are centered around:

• Backend Engineering
• Distributed Systems
• System Architecture
• IoT Systems
• Performance & Reliability
• Linux-based infrastructure

• Python
• Flask
• FastAPI (learning & experimenting)
• REST API design

• PostgreSQL
• MySQL
• SQL query optimization
• Relational data modeling

• Docker
• Docker Compose
• Linux
• Git

• C / C++
• ESP32 firmware
• Hardware/software integration
• Embedded systems

Backend system for predictive inventory control, focused on helping businesses optimize stock levels based on product demand.

Main features:
