About Me

I’m a software engineer driven by a passion for building complex systems from first principles. I thrive on the challenge of turning theoretical concepts into tangible, high-performance software, and I’m most at home architecting novel solutions from the ground up. This journey has led me to design and implement everything from a word processor built for extreme performance to the core UI of an embedded TV OS. My work is about crafting elegant, robust, and efficient solutions to foundational problems in software.

Areas of Focus & Expertise

My work is grounded in a deep understanding of computer science fundamentals, which I apply to specialized domains.

  • Core Disciplines: Systems Design & Architecture, Computer Graphics, Type Systems, Compiler and Interpreter Theory, Algorithmic Analysis.
  • Methodologies & Paradigms: Functional Programming (FP), Reactive Programming, Object-Oriented Programming (OOP).
  • Applied Specialties: UI Systems & Frameworks, Performance Optimization, Developer Tooling, State Management, 2D Rendering.
  • Languages: My primary tools are TypeScript/JavaScript and Rust, with deep experience in Go, C++, Common Lisp, and Haskell for more specialized problem-solving.

Professional Journey

My career has been a progression from building applications to building the platforms and systems they run on.

Open Source

REROI - github.com/PunGy/reroi

As Creator and Maintainer, this project is my exploration into the frontiers of reactive programming. I architected and built a high-performance library from scratch in TypeScript, developing novel approaches to fine-grained state management. This included implementing features like ACID-compliant transactional updates and prioritized scheduling to solve complex state synchronization challenges.

Yandex | Moscow, Russia

Senior Software Engineer | Oct 2023 - Present

I am a core R&D engineer on a greenfield project to build an innovative, browser-based office package, with a focus on a word processor designed to outperform existing solutions.

EPAM Systems | Kraków, Poland

Senior Software Engineer | Oct 2021 - Oct 2023

During my time at EPAM, I tackled large-scale systems challenges for two distinct projects.

  • On an Embedded Smart-TV OS, I architected core abstractions for managing asynchronous UI operations within a large Node.js application, significantly improving system stability. I also led an effort to overhaul critical low-level utilities, increasing test coverage by 30% and shipping a benchmark library to prevent performance regressions.
  • For a Security & Resource Management Platform, I stepped in to lead technical stabilization after a team restructure. By triaging the technical debt backlog, I unblocked feature development for the team. I also drove a major code unification effort, replacing a chaotic layout system with a purpose-built component architecture that accelerated future development.

Mentorship & Education: A fulfilling part of my role was mentoring engineers in advanced software design. I also revamped the company’s largest Computer Science course, directly improving the technical education for hundreds of my peers.

Earlier Career | 2016 - 2021

My earlier roles at Sperasoft, BuildSafe, Luxoft, and Hyperauto, along with my freelance work, built the foundation for my current focus. Highlights include:

  • Architecting a custom React Server-Side Rendering (SSR) engine and migrating a build system to esbuild, decreasing build times by 200%.
  • Leading a performance initiative that cut bundle size by 20% and measurably improved Web Vitals.
  • Architecting and delivering a PoC for a large-scale data-set processing pipeline, presented at CES 2020.
  • Introducing modern DevOps practices (Docker, Git) to a legacy environment, automating deployment and saving significant developer time.

Education

Vladivostok State University College | 2016 - 2019

  • Studied Programming and Computer Systems
