Proof of Work
Projects
Real problems, and what actually resolved them.
Advanced Self-Hosting Infrastructure (Docker + Reverse Proxy)
Problem — Relying on third-party platforms for services like file storage, media streaming, and code hosting often compromises control, privacy, and scalability.
Solution — Deployed a self-hosted infrastructure running on Docker containers, with applications such as Nextcloud, Jellyfin, Gitea, and Syncthing. Secured the environment with a Traefik reverse proxy, a WAF, and automated SSL/TLS.
Outcome — A scalable, secure, and private platform, enabling complete ownership of data and services while maintaining high availability and performance.

Custom OpenWrt Firmware & Router Configuration
Problem — Off-the-shelf router firmware lacked the features, security controls, and customization required for advanced labs and real-world security use cases.
Solution — Built and maintained a custom OpenWrt firmware, integrating a captive portal, custom firewall rules, QoS tweaks, logging/monitoring hooks, and secure update mechanisms.
Outcome — Turned consumer-grade routers into secure, policy-driven networking appliances — reducing attack surface and enabling guest isolation, SIEM-ready telemetry, and improved performance.

WordPress E-Commerce Website (Client Project)
Problem — A client needed a fast, secure, and reliable e-commerce platform to support growing online sales, but off-the-shelf hosting solutions were slow and insecure.
Solution — Designed and deployed a custom WooCommerce site on a manually optimized LAMP stack, integrating Memcached for server-side caching, client-side caching plugins, SSL/TLS with auto-renewal, MFA, firewall rules, and backup systems. Also handled Cloudflare DNS management, SEO optimization, and multi-payment gateway integration (bKash, Nagad, Rocket, cards, and bank transactions).
Outcome — A high-performance, secure e-commerce website that improved customer experience, boosted sales, and gave the client a scalable foundation for future growth.

Security Information & Event Management (SIEM) with Wazuh & ELK
Problem — Modern infrastructures generate massive amounts of logs, but without centralized monitoring, threats can go unnoticed until damage is done.
Solution — Architected and deployed a SIEM solution using Wazuh, the ELK Stack, and Elasticsearch, integrating log collection, real-time alerting, and visualization dashboards.
Outcome — Enabled proactive threat detection and streamlined incident response, improving visibility across systems and reducing mean time to detection (MTTD).

Intrusion Detection & Prevention System (Snort & Suricata)
Problem — Unmonitored network traffic leaves systems vulnerable to undetected intrusions and malicious activity.
Solution — Implemented and tuned Snort and Suricata IDS/IPS systems, building rulesets to detect and block suspicious traffic patterns, tested in both lab and production-like environments.
Outcome — Provided early warning against network-based threats, reducing the attack surface and enhancing overall network security posture.

Exploit Development & Game Hacking (Research)
Problem — Understanding software vulnerabilities at a deep level requires working hands-on with low-level systems, memory, and reverse engineering challenges.
Solution — Conducted exploit development and game hacking research projects — writing proof-of-concept exploits, reverse engineering binaries, and creating mods and automation scripts for games.
Outcome — Sharpened skills in reverse engineering, secure coding practices, and vulnerability research — directly improving the ability to identify and mitigate real-world software security flaws.

Telegram Battery Status Bot
Problem — Users often forget to monitor battery health and charging status on their devices, which can shorten battery lifespan or lead to sudden shutdowns.
Solution — Built a lightweight Telegram bot that monitors battery status and sends real-time alerts, providing insight into charging health and thresholds.
Outcome — Automated a simple but valuable use case, demonstrating practical automation with Python scripting, API integration, and lightweight notifications that improve user convenience.

AI Music Remover (In Progress)
Problem — Video editors and content creators often struggle with separating vocals from instrumentals in audio tracks for remixing, karaoke, or background scoring.
Solution — Developing an AI-powered tool that leverages machine learning models to isolate vocals and instruments with high accuracy — training and fine-tuning separation models and integrating them into a user-friendly interface.
Outcome — Will enable creators to work more flexibly with audio, reducing reliance on expensive proprietary software while showcasing expertise in machine learning, signal processing, and AI application development.
