Bridging Secure Architecture with Scalable Full-Stack Engineering

I am a Software Engineer and Security Researcher driven by the challenge of building digital systems that are as resilient as they are functional. With a background rooted in a “security-first” development philosophy, I specialize in architecting full-stack applications that prioritize data integrity without compromising on user experience or performance.

Engineering at Scale: The Rental Marketplace Project Most recently, I spearheaded the development of a comprehensive, Airbnb-style rental platform designed to modernize property management for student housing. This wasn’t just a CRUD application; it was an exercise in managing complex, real-world dependencies.

The Stack: I leveraged Fastify (Node.js) for its high-performance, low-overhead backend capabilities, paired with React to create a dynamic, component-driven frontend.

Integrations: I implemented MongoDB Atlas for flexible data scaling, Geoapify for geospatial search intelligence, and MailerSend for automated transactional workflows.

The Result: I successfully transitioned a manual, paper-based system into a fully digital ecosystem, focusing specifically on solving the “trust gap” between landlords and tenants through robust authentication and verification flows.

The Security Mindset: Vulnerability & Malware Research Parallel to my development work, I am deeply invested in Cybersecurity. I don’t just write code; I look for the ways it can be broken. I have developed Python-based security tools, including a Remote Administration Tool (RAT), to study malware behavior, stealth mechanisms, and defensive gaps in isolated environments. This offensive research directly informs my defensive coding—allowing me to implement patches and encryption logic at the foundation of every project I touch.

Technical Toolkit:

Languages: Python, JavaScript/Dart, PHP, C, SQL.

Frameworks: ReactJS, Flutter, Laravel, Fastify (Node.js).

Security: Malware Analysis, Vulnerability Research, Encryption Logic, Penetration Testing.

Cloud & Tools: Git/GitHub, Linux (CLI), MongoDB Atlas, RESTful APIs.

Beyond the Code I believe the best engineers are those who never stop being students. Whether I am mentoring peers in Laravel backend structures, contributing to open-source security repositories, or prototyping new mobile solutions in Flutter, I am constantly pushing to stay at the edge of what’s possible in tech. I thrive in collaborative environments where high-level problem solving is the daily standard.
