The presentation editor where science actually runs: equations, Python cells, charts, circuits and molecules are live objects rather than images. Grew out of Praxis, a prototype I built in late 2025.

• Designed the structured document model, editor architecture and backend services so people and AI systems manipulate the same objects directly, keeping AI-generated content editable instead of flattened.
• Shipped PowerPoint import and export, and an MCP interface through which AI assistants create and modify presentation objects programmatically.
• Migrated backend workloads to Google Cloud Run. 300 users and 2,432 decks created to date.

Procurement, inventory and catalogue services that unify Shopify, retailer, supplier and spreadsheet data into one typed model.

• Modelled 4,000+ SKUs across roughly 60 suppliers with typed ingestion and validation pipelines for pricing, packaging units, bulk-buy terms, landed cost and margin.
• Backed the pipelines with 183 automated tests; validators flag inconsistent costs and margin anomalies before they reach the live catalogue.
• Added provenance and audit trails so every catalogue change is traceable, reviewable and reproducible.

Led a distributed team of about ten engineers while building Python backends and APIs hands-on for production web and mobile apps.

• Owned architecture reviews, testing strategy, releases and sprint execution; shipped 30+ releases a year.
• Shipped FoundFast (iOS and Android): startup-idea submission, community voting and competitions, 3,000+ downloads.
• Shipped ManyRoads (iOS and Android): GPS-guided journeys with location-based checkpoints and user-created routes.
• Introduced automated testing and CI/CD with Pytest, GitHub Actions and CircleCI; mentored engineers in design, debugging and TDD.

The laboratory ERP and grading tools used daily by scientists and grading staff on a platform grading 500+ diamonds a month.

• Built lab records, diamond grading, report generation and workflow automation used every day by the grading team.
• Cut per-stone imaging time from about 3 minutes to about 45 seconds by automating detection and cropping of macro and nano diamond imagery.
• Built the customer-facing verification app and the Solidity contracts that mint each grading report as an NFT; 70+ reports issued on-chain.

Led engineering for an AI-assisted social-media publishing platform: backend, APIs, deployment and ML integrations.

REST APIs, authentication workflows and backend services for a character-building and visual-storytelling platform.

Authentication and SMS-verification workflows for secure user onboarding.
