Working mostly as a product engineer applying my skills to build LLM applications solving novel problems.

• Applied automatic speech recognition, including diarization, speaker identification

• Agentic Systems using mobile platforms

• Neural search engine

• Personalized assistants

I have started a non-profit to build a new programming language for smart contracts, after i built everything i wanted i passed everything to successors.

I have built:

• New language that compiles to another lower level one

• VS Code plugin

• Extensive documentation cite

• Community

I was involved in:

• Fundraising for the foundation

• Promoting and teaching developers to use a new language

Co-founded company and built a wide variety of products and services that generated over 20m$ of income. I have a team of a ~3 hand picked engineers and few other non-tech assistants. Company suffered explosive growth and i was responsible to keep infrastructure working and keep company in competitive shape.

I have built:

• Mobile, Web and Desktop apps using Typescript and React/React Native.

• Advanced scalable backend software in Go and Node.js

• High performance computing using GPU and FPGA, using OpenCL, CUDA and Verilog.

• Resilent infrastructure that required to withstand daily DDOS attacks that was a combination of multiple clouds and dedicated servers, such as: AWS, Google Cloud, Heroku, Digital Ocean and Hetzner.

• Various developer libraries and APIs that became popular within ecosystem, which includes Data APIs, unit testing tools, code generation, etc

Co-founded the company which started as data analytics company for governments that pivoted and became social app. We have raised over $2.4m and was part of Y Combinator W18 batch. I was responsible for tech and team performance. Eventually we achieved performance of consistent delivering every week which helped us to iterate quickly.

I have built:

• Automated cleanup, processing and sync of governmental data and data rich dashboards to visualise results.

• Mobile, Web and Desktop consumer apps using React and React Native.

• Voice and Video private and group calls using WebRTC and implemented scalable and reliable MediaSoup orchestration.

• Backend in Typescript, using Node.js, PostrgreSQL, Redis, FoundationDB.

• Cost efficient cloud infrastructure that was deployed to Google Cloud, AWS, Digital Ocean with help of few dedicated Servers and small local colocation in San Francisco.

Tech invented:

• GraphQL stack for backend and for client which was designed for scalable development.

• ORM for FoundationDB (which i presented at Apple's conference about FoundationDB

• High performant UI components for React Native including fully custom List rendering using high performance native APIs, high performance animation library, high performance graphql client that offloads a lot of computations to native thread.

I was involved in:

• Building a stable hiring pipeline

• Managing healthy team with help of a VP of Engineering

I was invited to participate in a stealth project, that was later released as Spaces which combines social and developer tools for teams in a single product. Our goal was to bootstrap a tech stack that would be suitable for large amount of developers to join the development from other teams.

I have built:

• Distributed backend using Akka, Cassandra, Postgresql and Redis.

• Typed API library that didn't need code generation and allowed fast iterations.

• UI components in React using Kotlin.js

• A messaging component of a product

I was involved in:

• Designing of a new state management library for client apps

• Helping Kotlin team to improve Kotlin.js

• React bindings for Kotlin.js
