• TCP/IP Tinkerer: Successfully crashed my OS kernel trying to hold 1,000,000 concurrent socket connections.
• Plumbing First: I build raw TCP socket servers, custom database engines, and VCS systems from scratch to learn the physics of software.
• Late Starter, Fast Run: Got into the game a bit late at 17, now grinding the hard stuff first.
• Core Focus: Systems engineering, network protocols, and high-performance runtimes.

• Languages: TypeScript, JavaScript
• Backend: Node.js, Express, Sockets
• Frontend: React, Next.js, HTML5/CSS3, TailwindCSS
• Storage: PostgreSQL, Redis (RESP), MongoDB
• Infrastructure: Docker, Docker Compose, Linux, Git

A high-concurrency seekable HLS video streaming server.

• AES-128 HLS Security: Generates dynamic cryptographic keys on-the-fly to deliver secure, encrypted segment files for live HLS streams.
• GOP-Aligned Transcoding: Spawns concurrent FFmpeg child pipelines enforcing strict keyframe intervals to align multi-bitrate resolution chunks.
• O(1) L2 Cache: Bypasses costly disk access by implementing an in-memory L2 Cache utilizing a Map combined with a Doubly-Linked List (LRU eviction).

A custom version control system written in TypeScript.

• Implements local content-addressable storage and serializes directory hierarchies into Merkle tree structures to guarantee absolute state immutability.

An in-memory TCP socket cache database mimicking Redis server specifications.

• Implements a custom RESP parser to handle TCP stream packet fragmentation, command pipelining, and keys eviction.

An AI-powered local documentation synchronizer CLI utility.

• Watches local git diff change events and interfaces directly with the Google Gemini LLM API to write codebase architecture updates to system README files.

• 🚀 Currently on a backend grind to become undeniable.
• 🤝 Open for backend/systems engineering opportunities, open-source contributions, and high-performance systems collaboration.
