Seyhan Van Khan

I build intuitive, reliable software that solves real user problems. I'm a product engineer combining strong frontend engineering with end-to-end product ownership, from customer discovery and workflow design to architecture, implementation, and launch.

ReactWise

Lead Frontend Engineer

– Present Cambridge, United Kingdom
  • Own frontend architecture and delivery while remaining hands-on. Established a unified design system, improved component architecture and accessibility.
  • Designed technical assessments and conducted frontend interviews; mentored two junior engineers through pair programming, regular feedback, and progressively challenging projects.
  • Split an 18 MB monolithic frontend bundle into smaller, dynamically loaded chunks in Vite. Reduced frontend-only deployment times from 30 to 10 minutes by deploying only changed monorepo components.

Software Engineer

– Cambridge, United Kingdom
  • Partnered with customers, founders, scientists, and engineers to design and ship product features spanning reaction-kinetics modelling, scientific visualisation, experiment management, workflows, and enterprise permissions.
  • Built a high-throughput experimentation (HTE) plate-design tool for configuring laboratory experiments, featuring interactive well editing, reagent and solvent calculations, stock-solution optimisation, composition visualisations, and dispensing-instruction exports.
  • Implemented enterprise capabilities including SAML, MFA, and frontend support for on-premises deployments with reduced outbound HTTP dependencies. Contributed to adoption by five of the world's ten largest pharmaceutical companies, including Pfizer, Roche, and Biogen.
  • Redesigned core interfaces, simplifying navigation and layouts, removing redundant UI elements, and standardising typography and component patterns. Introduced engineer-led product design, with engineers owning features from customer discovery and workflow design through implementation and launch.
