Richard Waller is a Senior Software Engineer in London with eight years’ experience building full-stack, ML-driven systems using TypeScript, Python and AWS. He has shipped high-impact products at scale—from a LightGBM car-pricing engine that prices thousands of vehicles daily and a PyTorch image classifier for 100k+ listings to payment and purchasing platforms that increased profit per unit and new revenue streams. Comfortable across frontend (Next.js) and backend (serverless, DynamoDB, API Gateway), he pairs pragmatic architecture with strong observability and security practices (Cloudflare, WAF, Datadog). At Cazoo he combined models and rules to boost offer acceptance and launched a Stripe-backed flexible payments system; earlier work includes open-source tooling at IBM that achieved notable community adoption. He favors iterative, metrics-led delivery and has a knack for turning documentation gaps into shared diagrams and onboarding assets that accelerate team velocity.
