Projects

Systems that had to survive contact with reality.

Each initiative paired narrative clarity with operating rigor — from safety and spatial intelligence to customer systems and founder-scale execution.

Representative GIS workspace: estate panel and satellite map with overlays (client UI anonymized).

200+ daily active users

Enterprise supplier compliance & deforestation monitoring

Owned backend architecture and product delivery for a confidential GIS SaaS used by global FMCGs and large agri‑supply partners — 24M+ ha on the map, 200+ daily active users, and roughly 60% faster reporting cycles vs. manual bi‑weekly runs.

Ranked neighborhood results with interactive map — representative PropTech UI.

58,000+ neighborhoods · sub‑second ranking

Neighborhood intelligence & preference‑driven home search

Led product and engineering for a PropTech SaaS that ranks 58,000+ UK neighborhoods in sub‑second time against weighted lifestyle signals — 1,000+ signups in month one, 900,000+ sales records in the scoring layer, and 80% of new users completing a search in their first session.

Map-first AOI selection with cadastral overlays — representative marketplace UI.

10,000+ users · 100+ exports/day

National geospatial data marketplace & self‑serve exports

Shipped a country‑scale SaaS where planners and GIS teams buy clipped, standardized layers from one catalog — 10,000+ registered users, 100+ automated export jobs per day, and roughly 70% faster data prep vs. manual hunting across government portals.

Time‑series gas probability traces with detection thresholds — representative monitoring output (anonymized).

~90% smaller models · ~3.5× faster inference

Edge environmental & fire intelligence — ML optimization and Earth‑observation validation

Partnered with a deep‑tech hardware startup to harden a proprietary badge‑class edge AI stack for real‑time environmental and fire‑risk signals: structured pruning and INT8 / INT4 quantization for on‑chip inference, sensor stabilization under temperature and humidity drift, manufacturing‑neutral baselines, gradient‑based input reduction, and VIIRS / GOES‑16 fusion with NASA FIRMS for high‑confidence event validation — roughly 90% smaller models with about 3.5× inference speedup while tightening operational trust for field teams and exec reviewers.
