Hey, I'm Nikita Kramarovsky
Full-stack engineer who builds and leads. Over a decade shipping mobile apps used by millions, the systems behind them, and now AI.
About Me
I build web, mobile, and data platforms, and lead the teams that ship them. I've rebuilt a telecom app used by millions from the ground up, shipped some of the first NFC payments on mobile, and lately I build with and around AI. I tend to go a layer deeper than the job strictly needs.
Companies I've Worked With
Technical Skills
I've worked across the stack: frontend, mobile, backend, cloud, and the infrastructure automation underneath. Strongest at system design and getting things from prototype to production, and I like leveling up the people I work with.

Projects
A selection of the platforms and tools I've built, from apps used by millions to tools I made to scratch my own itch.
A Storybook for typed LLM pipelines: edit one step and only the affected steps replay from cache, instead of re-running the whole pipeline to iterate on the last one. Structural run-diffs, stability and cost telemetry, a local-first CLI. MIT-licensed.
A learning platform that teaches through film: movie and TV scenes built into standards-aligned lessons, an LLM layer that grades student answers, and video streaming throughout.
A modular platform-as-a-service that powers multiple products, with identity, data, media, messaging, and LMS services. All infrastructure-as-code.
A CLI that turns Figma components into real codebases, generating React and React Native with design tokens carried through. Turns design-to-code from hand translation into a build step.
A white-label ticketing app for Capital One cardholders, built for high-traffic on-sales and partner branding. Owned the UX, partner requirements, and compliance.
Rebuilt the Rogers mobile app from the ground up as Android lead, and shipped it on time with low bug counts. Serves millions across Canada. Set up the CI pipeline and the shared foundation myFido was later built on.
