Summary

Backend and systems engineer specializing in Go and Python, with a focus on concurrent systems, API design, and infrastructure automation. Co-authored python-aria-mirror-bot, one of the most widely-forked Telegram automation platforms. Solved its core native dependency instability by designing a CGO-based MegaSDK wrapper exposed as a REST microservice — adopted across the broader ecosystem and starred by a senior MegaSDK contributor.

Projects

python-aria-mirror-bot (Co-author)

Co-built the original Telegram file mirroring bot that became the foundation for a widely-forked open source ecosystem — the canonical repo alone sits at 780+ stars and 1.2k+ forks. Handled async job queuing, multi-cloud uploads, service account rotation, and real-time status reporting. Adoption scale contributed to Heroku deprecating their free dyno tier.

Identified recurring crashes in MegaSDK's SWIG-based Python bindings. Designed and implemented CGO-based C++ bindings from scratch in Go (megasdkgo), then exposed them as a REST server (megasdkrest) so Python services could interface with Mega over HTTP — eliminating the native crash surface entirely. Starred by a senior MegaSDK contributor and adopted by other projects in the ecosystem.

MirrorBotGo

Full Go rewrite of the mirror bot with 45 releases. Embedded a GoJa JavaScript runtime to power an extensible DDL plugin system — scripts register via URL regex and resolve direct download links transparently before the transfer pipeline executes, enabling support for IP-locked links without user intervention.

Concurrent CLI tool in Go for Google Drive with recursive downloads, resume support, OAuth2, service account rotation, MD5 integrity checks, and real-time progress reporting.

flight-tracker

Async Telegram bot combining a stealth airline scraper (Playwright) with live FlightAware telemetry for real-time in-flight tracking — progress bar, ETA, and distance. Adds a reliability analytics layer over SQLite: completion scoring, delay percentiles, and aircraft-rotation trend analysis.
