Validator DevOps · Web3 Infrastructure · Security Research · Blockchain Tools

I work on blockchain infrastructure, validator operations, monitoring, incident analysis and practical tools for Web3 networks.

My current focus is on payment-focused blockchain tooling, validator reliability, dashboards, RPC operations and security-oriented infrastructure research.

Public community analytics dashboard for the Tempo network.

Tracks:

• network health;
• live blocks;
• stablecoins;
• payment lanes;
• MPP activity;
• whales;
• ecosystem data;
• public address activity.

Status: unofficial, independent community project.

Browser-only MVP for batch stablecoin payouts on Tempo Moderato testnet.

Repository: https://github.com/dvjromashkin/tempo-payout-cockpit

Flow:

CSV → validation → preview → Tempo Wallet → one atomic AlphaUSD testnet batch → local receipt

The app is:

• Moderato testnet only;
• AlphaUSD only;
• browser-only and non-custodial;
• without backend, analytics, telemetry or data collection;
• unofficial and independent.

• validator and node operations;
• RPC and production reliability;
• Linux server administration;
• monitoring and alerting;
• blockchain dashboards;
• payment infrastructure tooling;
• incident analysis and postmortems;
• Web3 security research;
• testnet and mainnet infrastructure operations.

My background includes Linux administration, blockchain infrastructure and validator operations across EVM-compatible and Cosmos/Tendermint-based networks.

I have worked with:

• Ubuntu / Linux servers;
• systemd, Docker, LXC/LXD;
• Grafana, Prometheus, Zabbix and Telegram alerts;
• PostgreSQL, Redis and production service monitoring;
• validator nodes, RPC endpoints and blockchain infrastructure;
• deployment, troubleshooting and operational recovery.

Some older repositories on this profile are validator/testnet contributions, forks, experiments or operational notes.

I am currently reorganizing this GitHub profile around active Web3 infrastructure, security and blockchain tooling work.

Pinned repositories are the best entry point.
