The path so far

A journey through
decentralized systems

Waves Platform
2016 — 2017

Contributed to the backend and frontend of Waves, one of the earliest platforms enabling anyone to issue custom tokens and run decentralized applications on a blockchain — following one of the most successful ICOs of its era.

Early infrastructure for token economies and crowdfunding on-chain.
Lisk
2017 — 2019

Played a major role in developing the Lisk CLI — the primary command-line interface and developer tooling for the Lisk blockchain platform, which focused on JavaScript developers building sidechain applications.

CLI Development Developer Experience
Tendermint & Cosmos
2020 — 2026

Joined Tendermint in 2020 and spent more than five years deeply involved in the Cosmos ecosystem. Worked across engineering, documentation, and ecosystem development.

Cosmos SDK & Documentation
Helped shape the framework and its documentation that powers hundreds of sovereign blockchains today.
tokenfactory module
Helped create tokenfactory tooling and guides at Tendermint — permissionless token issuance that became a standard pattern across major Cosmos chains including Osmosis and Neutron.
Ignite CLI (formerly Starport)
Helped build the scaffolding tool used by teams to rapidly create and launch Cosmos SDK-based blockchains. Many successful chains started here.
Ecosystem Engineering
As Engineering Ecosystem Manager, supported the growth of the broader Cosmos network through tooling, education, and developer support.
SG-1 Validator
2020 — today · Co-founder

Co-founded SG-1, serving as technical lead and devops lead. SG-1 operates secure, enterprise-grade validators for 100,000+ delegators across 9+ Cosmos networks — with a zero-slashing track record — while building open-source tooling, educational resources, and contributing to ecosystem reliability and developer enablement.

Impact

Tools and modules that others build on

Focus has always been on infrastructure and developer experience that enables broader adoption.

tokenfactory
Helped develop the tokenfactory module at Tendermint, enabling permissionless token creation on Cosmos SDK chains. It has become a widely adopted pattern for asset issuance across the ecosystem.
Adopted by Osmosis, Neutron, Juno, and others • Tutorial
Ignite CLI
Contributed significantly to what started as Starport and became Ignite CLI — the primary tool for scaffolding and developing Cosmos SDK blockchains. Used by teams to launch production networks quickly.
Enabled rapid development of numerous sovereign chains
Cosmos SDK Documentation & Education
Helped define and expand the official documentation and tutorials. Created educational tools like cosmos-bip44 and contributed to guides used during major upgrades (e.g., Stargate).
Lowered the barrier for new developers entering the ecosystem
