Please only bid if you have verifiable low-level experience with custom Chromium builds and hardware fingerprinting. We are developing a standalone Windows automation utility that interacts with complex web platforms protected by modern behavioral analysis and device-reputation systems. We need an engineer who understands low-level browser internals, hardware consistency, and human-like interaction physics. Required Technical Skills: Chromium & Hardware Fingerprinting: In-depth knowledge of browser identity vectors: Canvas noise, WebGL renderer/vendor emulation, AudioContext consistency, Client Hints, and TLS JA3/JA4 profiles. Experience with custom/patched Chromium binaries or driver-level modifications. Low-Level Protocol Automation: Direct communication via Chrome DevTools Protocol (CDP) without leaking debugger hooks or execution context traces. Experience with isolated automation architectures (avoiding default automation flags). Human Interaction Modeling: Mouse trajectories using Cubic Bézier curves / Fitts’s Law (smooth acceleration, deceleration, and micro-movements). Natural keyboard typing cadence with realistic physical key-to-key latency. Strict Exclusions: ❌ No basic Selenium or standard Puppeteer scripts using surface-level JavaScript overrides (Object.defineProperty). ❌ No third-party paid browser services or commercial subscription APIs. ❌ Must be completely self-contained and run on local hardware without leaving permanent device flags. Deliverables: Standalone Windows automation script (Python or C#). Clean browser runtime setup with full source code and documentation. Proof of clean multi-step flow execution past device-reputation checks without triggering security blocks.
