Custom SaaS and AI systems — in the stack the problem actually calls for.
Most engineering shops have one stack and recommend it for everything. We pick deliberately — and our work goes below application level, into database engines, real-time servers, and browser internals.
Our principal engineer has shipped work for a Fortune 50 beverage company, a global leadership-training firm, Kahf Browser, and a support SaaS we built and ran ourselves.
What we do
AI & LLM Systems
Retrieval, agents, and the data layer underneath them.

- Kubernetes
We have run a SaaS product, not only built one

Building and shipping a customer-support SaaS
- →Roughly $250,000 in lifetime-deal sales by first public launch
- →Feature-complete support platform built from an empty repository
- →Real-time email ticketing with a custom WebSocket layer
We write the infrastructure, not just the app
Our open source includes database engines, a real-time server, and systems tooling. It is the clearest evidence we can offer of how deep the work goes.
lumen
C++20
Embedded document and vector database engine. Slotted-page heap, B+Tree, HNSW and IVF vector indexes, BM25 full-text, MVCC with write-ahead logging, and runtime-dispatched AVX2/SSE2/NEON kernels in one portable binary.
corvid
Rust
Embedded multi-modal database combining vector, full-text, filter, graph, and geo indexes behind one interface.
pylon
Rust
Clean-room Pusher-compatible real-time WebSocket server.
Selected work
ThriveDesk
Building and shipping a customer-support SaaS
Architected and shipped a support platform from nothing, reaching roughly $250,000 in lifetime-deal sales at launch.
A Fortune 50 beverage company
From minutes to seconds on an enterprise platform
Cut page load times from minutes to seconds on a global product platform, and closed the security findings behind them.
A global leadership-training firm
Replacing a cloud dev environment with something roughly tenfold faster
Built a local development environment that replaced Amazon WorkSpaces and increased team efficiency roughly tenfold.
Kahf Browser
Shipping a Chromium-based browser and its update infrastructure
Built a custom Chromium browser with privileged extensions, plus the update server and release tooling behind it.
