Collaborators
Teams I've shipped with
From climate hardware to spatial platforms — calm delivery across org sizes.
How I work
A few lenses — not a laundry list.
If we work together, this is the shorthand for how I show up: sensemaking, systems, and calm execution.
How I think
Incentives and feedback loops first — what the system rewards, punishes, and hides — before interfaces or roadmaps.
Human systems
Behavior is data with dignity: cognitive load, trust repair, and the quiet moments where products win or fail.
Research → outcomes
Field truth, telemetry, and narrative compressed into falsifiable claims — then wired into how teams operate.
Operational intelligence
North stars with counter-metrics and healthy escalation — so velocity compounds without burning people out.

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.

Outcomes
Scaled acquisition (1,000+ users in 30 days), hardened search to sub‑second responses at full index size, held 99.5% uptime post‑launch, and shipped pass‑based monetization with automated reporting — a credible story for PM and tech‑lead interviews.

~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.

Outcomes
~90% model compression with ~3.5× faster on‑device inference, materially lower memory and I/O after quantization, measurably calmer sensor traces across devices and weather swings, and a defensible satellite cross‑check story for PMs and tech leads hiring into safety, climate, or edge ML.
