Interested in buying, licensing, white-labelling, or extending a codebase? Start with the codebase catalogue below. Each repository has its own maturity, dependencies, and license status; I confirm those details before quoting or promising rights.
|
Use a suitable existing foundation under the license that actually applies. For projects without an explicit license or with third-party restrictions, permissions must be resolved first. |
Adapt branding, flows, integrations, product requirements and deployment around your business. Quote covers the agreed changes, not an undefined promise of “everything”. |
|
Discuss a source transfer or acquisition only after checking ownership, existing licenses, dependencies, assets and prior obligations. An existing open-source grant cannot simply be turned into exclusive ownership. |
Review architecture, setup, dependency risk, data/security boundaries, current limitations and the work required before you invest in a codebase. |
|
Agree on environment configuration, hosting, CI/CD, release steps, documentation and a handover session. Secrets and third-party accounts remain buyer-owned unless the contract explicitly says otherwise. |
Extend a base repo or build a defined workstream. My portfolio lists separate engineering-service packages; codebase licensing is scoped and quoted separately. |
| Codebase | What is demonstrable from the project material | Best-fit conversation | Source / current signal |
|---|---|---|---|
| Aura Arena | MediaPipe CV + WebGPU, scoring across 100+ movement sub-disciplines, Supabase Realtime multiplayer, PWA/offline work | CV demos, movement products, fitness or interactive-game foundations | Repo · Live · Last commit |
| Aura Studio | 45+ typed node types, multi-model LLM routing, RAG-oriented flows, per-node streaming, export paths described in the README | AI workflow builder, internal automation studio, LLM/RAG prototyping | Frontend · Backend component · Live |
| Neev | React Native / Expo family OS, household-scoped spaces and Firebase rules described in project documentation | Private family/productivity apps, role-scoped mobile products | Repo · Product |
| BlinkQuest website | Next.js 16 static marketing site, Tailwind CSS v4, structured metadata, sitemap and Cloudflare Workers deployment described in README | Product landing sites, documentation hubs, Cloudflare static deployment | Website repo · Live |
Live repository metadata changes over time. The links above go to the source/history; the exact branch, commit, build state and transferable scope must be confirmed for each deal.

Digital products in pre-order: React Native Architecture Playbook ($49) · Production RAG Starter Kit ($79)
These are published engineering-service prices and pre-order listings from the portfolio, not prices for buying source-code IP. Confirm current terms, deliverables and availability on the service page.- Scope: exact repository, branch and commit SHA, what is included and what is excluded.
- Readiness: current setup commands, environment-variable inventory, demo/build status, known defects and unfinished areas.
- Risk: dependency and third-party asset/license list, external service costs, secret ownership, data/privacy boundaries and deployment dependencies.
- Terms: license type or transfer structure, permitted use, exclusivity if legally available, support period, payment milestones and acceptance criteria.
- Handoff: install/deploy walkthrough, documented change points, and an agreed post-purchase support option.
No invented revenue, download counts, “production-ready” guarantee, or made-up repository prices. Commercial terms depend on the codebase, current IP/license position, scope, and support requirements.

A wider workshop of health-tech modules, diagnostics interfaces, wellness experiences and starter foundations. Each project has its own maturity; these are presented as inspectable codebases, not as a claim that all 19 are production-ready or transferable under a clear license.

- Measure the constraint. Frame budgets, latency, release time and failure modes are product requirements.
- Separate facts from assumptions. Product claims link to case studies; live GitHub signals use the actual repository.
- Design for operations. CI/CD, observability, rollback paths, dependencies and operating cost belong in the architecture.
- Make handoff part of the product. Setup instructions, license clarity and a list of known gaps make code easier to trust and extend.

I don’t list made-up purchase prices. Codebase value depends on ownership/IP, license, completeness, dependency costs, buyer rights, customizations, and support. I’ll quote after confirming which source and rights can actually be offered.

To get a useful quote, include the repository/product, intended use, preferred option (license, white-label, source acquisition, deployment, audit, or custom build), budget range, timeline and support requirements. I’ll confirm current scope and licensing before promising a transfer or exclusive rights.
