Sustainability impact venture co-founded by WWF and BCG, providing supply chain traceability for global brands. Standardised messy 'first three miles' farm data into EPCIS, then surfaced it through dashboards used by Nespresso, Austral Fisheries, and internal teams to validate ethical sourcing claims and farmer payments.

• Sole engineer on the main analytics dashboard. Built and maintained the whole thing. Plotly Dash for the analytical core, React and Next.js for the consumer-facing pages.
• Built the traceability and payments validation system used by Nespresso to verify coffee sourcing across Rainforest Alliance and their internal AAA premium-farmer program, including checks that base prices tracked the London robusta price index and that farmer payments matched contracted standards.
• Modelled supply-chain relationships so infiltration, exfiltration, capacity breaches, and untraced origin coffee became queryable patterns rather than per-supply-chain spot checks.
• Worked with Austral Fisheries to validate the legal provenance of toothfish and prawn catches.
• Replaced bespoke per-cluster orchestrations in Dagster with a YAML-configured, data-contract-driven ingestion layer. New supply chains can be added by config now.
• Built a data entry flow that made it hard to put bad data in: input checks, guardrails, and reviews at the point of capture. Plus monitoring for ingestion accuracy and frequency across all supply chain feeds.

UK pensions consultancy. Core contributor on the frontend of a multi-tenant research platform used by several thousand consultants across 7 tenants to track investments and maintain observability across portfolios. Joined as a junior; promoted to leading a frontend team within two years as the company scaled from 10 engineers to 8 teams.

• Key contributor through my junior years, then led frontend architectural decisions on a React and TypeScript multi-tenant dashboard. Sensitive financial data; tenant isolation was the design constraint everything else worked around.
• Led a five-person frontend team focused on feature delivery, consistently the highest-performing team on UI work.
• Introduced Cypress E2E testing across the platform, which raised deployment confidence and cut human error at release time.
• Chaired the Bristol charity committee. Helped a charity left dry by multiple high-cost agencies. We ran a one-day workshop to surface issues, then migrated their database and supporting infrastructure onto Airtable. Pushed for more company-sponsored charity days and helped colleagues find their own.
