I design and ship web products with React, Next.js and Node.js, covering frontend architecture, performance, backend APIs and applied AI.

Proof of work
Three projects showing the initial problem, my ownership and the measurable result.
10+ years in product engineering
Lead Product Engineer
I work at the boundary between product and engineering: clarify the problem, choose the architecture, build the solution and own its performance and reliability.
Applied AI
I have turned AI ideas into working tools, including experimentation platforms, NLP for legal documents and developer assistants.
Core areas
Lead Product Engineer
Mobile LCP on Neverless.com exceeded four seconds. I reduced p75 LCP to 1.16s and INP to 62ms, then built an internal operations system from the interface through to the APIs. It reduced manual work by about 60%.
Founding Engineer
As a Founding Engineer, I built the frontend for a medical aesthetics marketplace on Next.js, including search, discovery and secure booking. I also developed an AI-powered A/B testing system for users and clinics in the UK and US.
Lead Software Engineer
Led frontend engineering for a private wealth platform. A team of five released the first version in 10 months, and the product supported a $20M funding round. I introduced strict TypeScript settings, CI/CD, Playwright and TabbyML, then led delivery as the team grew to 25 people. Delivery speed increased by 50%, while production incidents fell by 80%.
Senior Software Engineer
For Revolut's main website, serving 4M+ monthly users across 80K+ pages, I reduced load time by 75% and Time to Interactive by 45% while maintaining GDPR compliance and accessibility.
At Revolut Credit, I built customer applications and internal tools for a product serving 100K+ customers. I maintained 99.97% availability with 97.8% test coverage and created a shared React component library for internal systems. Feature delivery became about 30% faster, and defects fell by 30%.
Senior Software Engineer
Rebuilt the frontend infrastructure and delivery pipelines. Build time fell from two hours to 20 minutes, and releases became three times more frequent. I added SSR to search and booking, cutting initial page load time by 45% and increasing organic traffic by 20%.
Software Engineer
Built React Native features for Rocketbank and developed a digital mortgage MVP from scratch. The simplified application flow increased completed applications by 20%.
Co-founder / CTO
Co-founded a legal document automation startup and led a team of six engineers. The product cut document preparation time for clients by 50%.
Software Engineer
Built three frontend products with jQuery, Node.js, D3.js and Sass, focused on dashboards and interactive data visualisation.
I turn unclear requirements into released features, from interface design and APIs to production rollout.
I design React, TypeScript and Next.js applications and design systems that help teams move faster.
I measure LCP, INP and CLS, find bottlenecks and verify improvements with field data.
I ship AI features, introduce developer assistants and run focused experiments before scaling an idea.
I build APIs and services with Node.js and Nest.js, and work with Java and Kotlin when the product requires it.
I establish code review practices, mentor engineers and create a clear path from development to release.
Hi, I'm Dmitrii.
I'm a Lead Product Engineer at Neverless. I take product work from problem definition to production: shaping the solution, building the frontend and backend, setting up the infrastructure and owning the release.
I am also the lead organiser of MoscowJS, a JavaScript community that has held 63+ meetups. Outside work, I follow AI and investing, take photographs, read about history and astronomy, and run.
