What we do
We ship products, publish selected code, and take on scoped software projects with research and industry partners. Each engagement starts with a clear problem and a practical deliverable.
AI systems
Coding agents, model routing, workflow DSLs, and LLM-oriented language experiments for real developer environments—including public work such as BeanAlis and JapalityBean.
Explore AI workScientific software
Software for sequence data, chemistry learning, visualisation, and research workflows—on mobile and as command-line tools when a problem needs more than a prototype.
View scientific workProduct engineering
A published portfolio across science, education, utilities, and games on the App Store and Google Play—plus selected open-source repositories on GitHub.
Browse appsMobile apps
Consumer and productivity apps are distributed through official app stores. Store listings govern availability, pricing, and product-specific privacy.
Education
Structured Korean learning from Hangul and vocabulary through grammar, reading, and review.
Science
On-device sequence analysis and design exploration for research and productivity workflows.
Developer tools
A mobile hex viewer, byte editor, and binary inspection toolbox.
Selected open source
A subset of our work is published under open-source licences. Most mobile apps are proprietary store products; only repositories listed on our Open Source page (and GitHub) are public source.
TypeScript · AI agent
AI coding agent for the terminal—multi-step tasks, MCP tools, hybrid routing, and verify gates.
Rust · LLM language
Experimental LLM-first systems language and compiler exploring how models read, generate, and repair code.
Rust · Scientific
Sparse k-mer, splice-aware RNA-Seq aligner designed for resource-constrained environments.
Collaboration
We partner with universities, research groups, and companies on AI systems, scientific software, and product engineering. Engagements are written agreements with defined deliverables—not open-ended retainers by default.
How collaboration worksClear problem firstIntended users, success criteria, and constraints before feature lists.
Practical deliveryWorking software, documentation, and handover you can operate.
Sensible data handlingShare only what the project needs, through channels agreed in writing.
How a project starts
Tell us the problem and the outcome you need. We review fit and scope before any detailed data exchange or development work.
Organisation, objective, expected outputs, and approximate timeline—without confidential payloads.
Technical fit, inputs, risks, responsibilities, and whether we are the right partner.
Deliverables, schedule, confidentiality, IP, and commercial terms before work starts.
