Selected work · 05
Backend infrastructure, a knowledge graph, an Android player, developer tooling, and a desktop dock — each built end to end, and each with its own constraints.

Realtime backend
An actor-based WebSocket server for high-throughput direct messaging. One isolated task per session, routing over channels with no shared mutable state and no mutex anywhere on the hot path.

Knowledge graph · Agent memory
Notes become a graph; the graph becomes memory any agent can use. Type a plain-language note and Weave extracts the concepts and relationships itself, then serves them back over MCP — search, recall, remember — with every node keeping its provenance.
02 / 05
A Weave note graph: people and concepts extracted from a note about FBI behavioral profiling work, joined by typed relations such as interviews, works as and leads to.

Music player
An Android music player built around one idea: your music, wherever it lives. Shipped through GitHub releases rather than an app store.
03 / 05
Developer tooling
One command for most of git. A published Rust CLI that walks beginners through the workflow and refuses to stage the things you would regret, like .env or node_modules.
04 / 05
Systems utility
A cross-platform VPS file browser over SSH and SFTP. Rust native layer with async session pooling and a key vault, React and MUI on top, shipped to desktop and Android from one codebase.
05 / 05
Backend
Actor-based messaging, low-latency lookups and rule-driven workflows, written in Rust with Axum, Tokio and WebSockets.
Distributed systems
PostgreSQL partitioning, Redis caching and quotient filters, picked per access pattern rather than by habit.
Delivery
Containerised builds, Jenkins pipelines and Kubernetes deploys.
Open source
Every project here is public.
I care about the parts that are hard to see: what happens under contention, where latency actually comes from, and whether a system still behaves when one piece of it stops answering.
This is my place for in between. Have a good read.

Discussing the problem of software inconsistencies across different environments and how Docker and Jenkins provide a robust solution.
Internships, open-source collaboration, or a second pair of eyes on an architecture decision.
