☁️ Layer 4 • AeroCloud — Self-Hosted PaaS Engine
A terminal-first cloud orchestrator executing zero-config container deployments.
-
Container Sandboxing: Hard Linux cgroups runtime enforcement (
512MB RAM/1 CPU core) preventing host memory exhaustion. -
Go Port Scanner: Embedded
$O(\log N)$ binary resolving machine-global ports via IPC pipes to eliminate race conditions. -
Zero-Trust Auth: Constant-time XOR token verification (
crypto.timingSafeEqual) immune to timing side-channel attacks.
🗄️ Layer 1 • proto-redis — TCP Key-Value Engine
An in-memory database implementing Redis wire specifications over raw TCP sockets.
- RESP Protocol Parser: Low-level state machine handling TCP packet fragmentation, streaming buffers, and command pipelining.
-
LRU Memory Eviction: Hash-map index combined with doubly-linked list for
$O(1)$ key eviction under memory pressure.
🎥 Layer 3 • video-streamer — Adaptive HLS Pipeline
A high-concurrency video delivery server with on-the-fly stream encryption.
- Deterministic Chunking: Concurrent FFmpeg child pipelines enforcing GOP-aligned keyframes across multi-bitrate profiles.
- In-Memory L2 Cache: Sub-millisecond segment delivery bypassing filesystem reads.
📦 Layer 2 • git-lite — Version Control Core
A Git-compatible version control engine written from binary specifications.
- Cryptographic Immutability: Content-addressable object store (
blobs,trees,commits) serializing directory graphs into Merkle trees.
⚡ Layer 5 • sync-cli — Git-Diff Doc Engine [NPM Package]
Developer tooling published on NPM to automate architecture synchronization.
- AST & Diff Parsing: Intercepts git staging events and AST tree diffs to reconcile codebase changes with active system architecture docs.
Languages : Go, TypeScript, JavaScript
Systems & Infra: Linux (cgroups, namespaces), Docker, Raw TCP/IP, Sockets
Data & State : SQLite (WAL mode), Redis (RESP), PostgreSQL
Full-Stack UI : React, Next.js, TailwindCSS (for developer dashboards & web tools)
Approach : Profile before optimizing. Understand memory layouts. Build from first principles.
- Open to systems engineering, infrastructure, and high-performance backend roles.
