Python engineer building and operating Solana trading infrastructure — market data,
execution-cost measurement, and automated execution. I ship end-to-end: design,
deploy, and run services unattended in production under systemd, with monitoring
and kill-switches.
Open source: solana-tca-monitor (github.com/Alex-profff/solana-tca-monitor) — a
transaction-cost-analysis service whose cross-source reconciliation caught two real
data bugs a single source would have trusted (postmortem + regression tests in repo).
I also run a private automated execution system on Solana 24/7 (strategy private,
architecture happy to discuss).
Stack: Python, asyncio, SQLite, systemd, Solana on-chain data (Jupiter / DexScreener /
Helius), Telegram bots, Git/CI. Open to remote backend / data / trading-infrastructure roles.
