Work
Selected case studies: client and programme delivery (including Nesta-linked work), plus in-house products and pre-release lab R&D. Summaries cover context, responsibilities, and public references, with clear attribution wherever third parties or programmes are involved. The next two sections separate delivered client work from in-house products and R&D.
Delivered / public client work
The Aires de Río / Habitat Prime case study is the deepest shipped narrative—live URL, deployment, lead pipeline, and campaign results—when you want to read end-to-end delivery first.

- Live
Aires de Río / Habitat Prime
Promotional web presence for a residential development in Santiago del Estero: narrative site, interactive area map, floor plans, downloadable technical PDFs, lead capture, and admin tooling—live at airesderio.com, built with SvelteKit.

Nesta-related data platforms
- WAIfinder — UK AI ecosystem map — Supercluster clustering, org pinning, Svizzle/Mapbox.
- Heat Pump Market Tracker — Geographic dashboard — map–chart cross-linking, a11y, backend pipelines.
- Dapsboard — DAPS query builder — runtime type system, XState explore machine, MongoDB cache.
- Svizzle — Open-source Svelte viz library — Mapbox-in-Svelte, ScreenSensor, A11yMenu.
Embedded engineering on Nesta ecosystem open tools: Svizzle Svelte viz library (including Mapbox-in-Svelte), WAIfinder UK AI map with Innovate UK, Dapsboard, EURITO indicators, Heat Pump Market Tracker (geographic dashboard, chart–map cross-linking, a11y, backend pipelines), and annotation backends—map-first geospatial UX, layers, and filters alongside accessible dashboards.
In-house products / R&D
Commercial product work sits next to independent and in-house R&D: Color Lab is live open-source independent browser-visualization research (MIT); Escriba Finanzas is the in-house system moving toward first public release; the lab write-up is explicitly pre-release research (no stable public demo)—architecture and intent only—so technical depth is visible without implying parity with shipped client work above.

- Pre-release
- In-house
Escriba Finanzas
Commercial product in active in-house development: SvelteKit + PostgreSQL RLS, Drizzle, multi-tenant credits, payments, and legal case files—migration from Classic ASP. Targeting publication and later commercialization (no customer-facing URL yet).

- Open source
- In-house
Color Lab
Independent R&D by Sebastián Ferreyra Pons, featured by Infomerx: MIT open-source live public beta — WebGL2 gamut solids, observer-aware instruments, per-list palette pipelines, and client-side document sharing.

- Pre-release
- In-house
Engineering lab / R&D
- Trama Audio Graph — Forensic audio restoration — node graph, WASM/WebGPU spectral path.
- Parametric wing playground — Flying-wing geometry and aero feedback — SvelteKit, Three.js, FastAPI / NeuralFoil.
Lab / pre-release (no public demo): Trama Audio Graph (forensic audio, Svelte 5 + WASM/WebGPU) and a parametric wing playground (SvelteKit, Three.js, FastAPI + NeuralFoil for near–real-time design feedback; roadmap: two-phase optimizer with progressive CFD on filtered candidates; optional bell spanload among other spanloads). Evidence of technical range—not a product you can adopt today.
