Fluid - github.com/PunGy/fluid

Creator & Maintainer

  • Architected and implemented a high-performance reactive programming library from first principles in TypeScript, exploring novel approaches to fine-grained state management.
  • Introduced such features as ACID-compliant transactional updates, and prioritized scheduling, to solve complex state synchronization challenges.

Yandex | Moscow, Russia

Senior Software Engineer | Oct 2023 - Present

Core R&D engineer on a greenfield project to build an innovative, browser-based office package and especially a word processor designed to outperform all existing solutions.

  • Spearheaded the architecture for the desktop version (Electron), ensuring code reuse and maintaining feature parity with the web-based application, successfully prototyping and validating a hybrid architecture for a local-first environment.
  • Invented and formalized a novel Domain-Specific Language (DSL) on top of TypeScript to manage and query complex document selection states, proving its ability to reduce the logical complexity, prevent entire classes of state-related bugs, and enabling developers to add complex new selectable objects (e.g., tables, embedded media) in under a day.
  • Engineered a platform-agnostic DevTools and state inspection library from scratch, enabling real-time modification and debugging of the application state and graphics, similar to Pixi.js DevTools. It makes possible to find and inspect bugs in seconds and provide interactive way to develop and test new features.
  • Implemented a non-indexing, asynchronous full-text search engine capable of querying 1M+ characters across a nested document tree in under 300ms on low-spec hardware, while maintaining a 60fps typing experience.

EPAM Systems | Kraków, Poland

Senior Software Engineer | Oct 2021 - Oct 2023

Project 1: Embedded Smart-TV OS

  • Architected and implemented core abstractions for managing asynchronous UI operations on a large-scale embedded Node.js application, improving system stability and predictability.
  • Overhauled and stabilized critical low-level utility modules, increasing test coverage by 30% and shipping a benchmark library to prevent performance regressions.
  • Maintained a suite of developer tooling (Bash) which automated device connection and code deployment.

Project 2: Security & Resource Management Platform

  • Led technical stabilization efforts after a team restructure by triaging and prioritizing the technical debt backlog, which unblocked feature development for a team of 6 engineers.
  • Drove a major code unification effort, deprecating a chaotic layout system in favor of a new, purpose-built component architecture, creating dozens of reusable abstractions that accelerated future development.

Mentorship: Mentored groups of engineers in advanced software design courses. Revamped the company’s largest Computer Science course, directly improving the technical education for hundreds of engineers.
