Chrome Extension Development Projects in ColomboChrome Extension Development Projects in ColomboTech Copilot | AI Chrome Extension for Automotive Technicians
Tech Copilot is a production Chrome extension built for automotive technicians. It works directly inside the browser as an AI assistant, helping technicians understand repair information, work with VIN-specific context, capture screenshots, and get diagnostic guidance without constantly switching between tools.
I built the Chrome extension architecture and continued developing the product across multiple paid milestones, taking it from the initial MVP into a polished live product.
Key features include:
• Manifest V3 Chrome extension
• Floating browser-based AI assistant
• OpenAI-powered responses
• Gemini Pro RAG with VIN-specific context
• Screenshot, snip and scroll capture
• Conversation modes and persistent state
• Usage-based free trial and monthly limits
• ExtensionPay subscription integration
• Freemium access and upgrade flows
• Production debugging, testing and ongoing improvements
The extension is live on the Chrome Web Store and has been developed through a long-term Upwork engagement with multiple completed milestones and a 5.0 client review.

RoboApply and Sociax are two separate job-application automation products I worked on, both focused on reducing the manual work involved in applying across complex ATS platforms.
For Sociax, I built an AI-powered Chrome extension that reads the current job description, compares it with the user’s saved resume, and generates an ATS match score, missing keywords, tailored resume bullets, and a cover letter. I then worked on the next phase: one-click application automation that opens external career pages, fills application forms, uploads the correct resume, answers common questions, and submits where possible.
For RoboApply, I worked on the multi-ATS automation layer for an existing auto-apply platform covering major job boards and ATS systems. The client had already tried more than 20 developers over the previous year without getting a reliable solution working. I built the first working Ashby integration within one week, which led to me being brought on for additional ATS integrations.
Key capabilities across both systems:
• Chrome Extension / Manifest V3 architecture
• AI resume and cover-letter generation
• ATS match scoring and keyword analysis
• Automated form detection and field mapping
• Resume and file upload automation
• Multi-step application flow handling
• Support for Greenhouse, Workable, Ashby, Workday, Oracle and other ATS platforms
• React-controlled form input handling
• AI-generated answers for screening questions
• CAPTCHA pause-and-resume workflow
• Application progress tracking and submission state
• Saved applicant profile and reusable application data
The work required handling very different form structures across ATS platforms, including dynamic React inputs, file uploads, multi-page workflows, validation, and platform-specific edge cases.
