Low-Latency Python Engineer — Anti-Bot / Cloudflare / Performance
Budget: $250 – $750 USD
Wanted: Expert Low-Latency Python Engineer — Thinking & Research Partner
A competitive, time-critical system where milliseconds decide the outcome.
I need an expert who will think and research WITH me — not just an implementer.
Required Precise Experience (Mandatory)
- HTTP / anti-bot stack: curl_cffi / curl-impersonate, TLS fingerprinting (JA3/JA4), Cloudflare / anti-bot bypass.
- Advanced Python asyncio: concurrent requests, racing / hedged requests, precise timeout control.
- Low-latency HTTP: HTTP/2 multiplexing, connection keep-warm, cutting TLS-handshake time, analyzing every round-trip.
- API reverse-engineering: network capture, JWT decoding, understanding CQRS / async-polling flows.
- Methodical performance measurement: p95 / tail latency, controlled A/B, profiling, distinguishing the client-side bottleneck from the server-side one.
Preferred
- Orchestrating multiple distributed workers across Linux VPS (concurrency, request coalescing).
- Chrome MV3 extensions (service workers) + Node.js.
- Background in real-time / HFT / trading / large-scale web scraping.
Your Role
You diagnose the bottleneck, raise hypotheses, design measurement experiments, and propose solutions backed by measured evidence — not guesswork.
Full confidentiality required; details shared after an NDA.
To apply (screening): briefly describe one latency or anti-bot problem you personally diagnosed — and exactly how you measured it. Generic proposals will be ignored.
