📍 South Africa | 🛠️ Developer, tinkerer, open-source maintainer | 🧠 Tool-first builder | 🌐 jpdelarey.co.za

I build tools that remove friction, surface signal from noise, and make systems easier to reason about. Most projects start as something I need, then slowly turn into something others might find useful.

BioAxis is where my engineering and genetics backgrounds meet. I founded it to build software and tooling at the intersection of biology and data — bringing modern web platforms, analysis pipelines, and clean interfaces to a domain that often runs on spreadsheets and gut feel.

Nuvio is a Pretoria-based application development company building custom web, mobile, and business software for clients including Vodacom, BCX, Ford, Tongaat, and King Price Insurance. As Technical Director I set the technical direction across the team — architecture, delivery standards, and the engineering culture behind products like FabricFour Learning and FabricFour Legal.

• 🧭 Internal dashboards for turning messy data into calm interfaces
• 🧮 Developer utilities for APIs, logs, and workflows
• 🧪 Experiments around AI as a practical tool, not a gimmick
• 🔌 Automation and glue code between systems that do not quite fit

Hydra is my flagship project: a cross-platform desktop app to orchestrate Claude Code and OpenAI Codex agents in parallel, with live terminals, session resume, and manager-agent orchestration.

• Parallel multi-agent workflows in one workspace
• Claude Code + OpenAI Codex support in the same app
• Session continuity, headless runs, and usage visibility

A lightweight toolkit for crafting, previewing, and shipping transactional emails without the bloat of a full marketing stack. Focused on clean templates, fast iteration, and predictable rendering across clients.

Turns Google Sheets into fast, queryable backends for small apps and prototypes. Designed for the moment you need real data behind a UI but a full database is overkill.

A roguelite idler where a script-driven party delves dungeons on its own. The game is in the loadout and logic you write — combat plays itself out while you tune the strategy.

Most repositories here fall into a few buckets:

• Small tools I use regularly
• Experiments and prototypes
• Internal tools that grew legs and went public

I design practical tools for agent-first engineering workflows.

• Building tools to support real-world systems
• Improving dashboards and developer ergonomics
• Exploring how AI fits into existing workflows
• Gradually open-sourcing more internal utilities

Occasionally I write short notes or documentation alongside projects when something is worth explaining.

• GitHub issues and discussions
• Email in profile

Build things you want to use. Keep them small. Let them grow naturally.
