TON Core

TON Core | Yerevan, Armenia · Remote

When I joined TON Core, smart contract development relied on a fragmented set of tools. I led the effort to rebuild and unify the developer ecosystem around Acton, covering language tooling, IDE integrations, testing, debugging, deployment, and local infrastructure.

• Unified compilation, testing, debugging, deployment, and language tooling in Acton, with Acton Studio providing a local web workspace for the toolchain
• Built Acton’s Tolk analysis pipeline and a Tolk static analyzer with an extensive set of rules
• Enabled real TON networks to run locally with Localton, including validators, a liteserver, TON Center v2/v3 APIs, and indexers
• Connected the toolchain to editors through the TON extension for VS Code and language server, and led the IntelliJ TON 4.0 release with Acton support
• Developed actonscan to inspect and debug deployed contracts and transactions, with source code debugging, message deserialization, emulation, and a testnet faucet
• Built Wallet Engine, a shared Rust core powering Telegram’s native wallet in the iOS, Android, and Desktop apps, with bindings for Swift, Kotlin, C++, and TypeScript/WebAssembly

TON Studio

TON Studio | Yerevan, Armenia · Remote

Worked on the Tact compiler and developer tooling. Over six months, I fixed over 100 bugs, implemented more than 40 features, built a language server and integrations for VS Code and JetBrains IDEs, and created a formatter. These changes significantly improved Tact’s usability and stability.

• Created language server and VS Code extension
• Created Fift assembly, BoC, TL-B language servers inside Tact language server
• Created plugin for JetBrains IDEs
• Created CST parser generator and formatter for Tact
• 200+ commits in the compiler repository

Alongside the Tact toolchain, I built TON debugging and analysis tools and contributed to the TVM documentation:

• Created a new version of the TVM disassembler
• Created TASM — a complete assembler for TVM bitcode (900+ instructions, Text assembly -> Bitcode and vice versa)
• Created TxTracer — a tool to debug and emulate any transaction in TON
• Created TVM Assembly Playground and Godbolt-like explorer for FunC code
• Wrote several articles about TVM internals in TON documentation

Moved to the TON Core team to develop tooling and infrastructure for the whole TON ecosystem.
