Real-Time Automation of the desktop/browser and Real-TIme video analysis/ Complex workflow automation. When Playwright and selenium just doesn't do the job and you need more than the standard automation tools can provide let's talk. Legacy Application automation. If you are still stuck with a program that was written twenty years ago then I've been there and done that. We should talk about what is possible. Cross platform Desktop automation (PySide. .NET) - Automate repetitive manual processes consistently and safely. Automate legacy applications to eliminate error prone drudge work like Runescape grinding, etc Cross platform GUI Desktop applications with PySIde6. Telegram Bot - process channels in real time using API or Web N8N - self hosted, dockerized or in the cloud. Browser automation - Many tasks are bound to the web, and require the same information to be retrieved and processed with multiple steps. Automation eliminates many of the errors that manual processes introduce Automation to work with sites that make online offers on a "First-Come, First-Serve" e.g. BPO (Broker Price Opinion), service and maintenance Work Orders and Assignments with user defined filtering (e.g. zip codes, price range, work order type) Auto Accept, in fact auto anything. If it's technically possible, can do. Remediation - lots of experience in bringing projects that are problematic for reasons of performance, stability, and timeliness back up to speed. Gaming - many games like OSRS, Runescape, Poker, etc require a lot of "grinding" - the need to repeatedly perform boring, mind numbing steps using the mouse or keyboard to progress or wait for favorable setups. You can use automation to handle the grind for you. Recent projects include: Implementing solutions that integrate web based front ends with legacy backends to provide legal compliance. Game automation, Automated trading and monitoring of financial signals and alerts, Advanced browser extensions, custom image processing, SERP and more. I'm a native English speaker with excellent communications skills and many years of experience. Please review my recent work history for details.
