Ann Catherine Jose

I’m Ann Catherine Jose, a software developer specialized in building full-stack web and native mobile applications. As a lifelong learner and builder, I’ve always loved learning different technologies and creating valuable solutions for people.

I find joy in the immersive experience of learning and coding for hours - being in the flow. My expertise is in rapidly developing fully functional modern web applications using the best technologies and tools, including AI at the appropriate level.

Professional Journey

My career spans over two decades in the software industry, with significant engineering roles at major tech companies. Prior to my last position, I held roles at Philips, SAP and Tata Infotech, as individual contributor and engineering leader. These experiences laid the foundation for my technical expertise and leadership approach.

During my 12-year tenure at Intuit, I led the Engineering organization for QuickBooks Platform and Mobile. As the Head of Engineering, I collaborated closely with Product, Design, and Marketing leaders to deliver best-in-class solutions for our customers. My legacy includes driving the QuickBooks mobile strategy, completing high-risk, long-term infrastructure initiatives in QuickBooks Platform, and establishing a strong foundation for Gen AI in Intuit’s Small Business group.

Career Pivot

In 2023, I made a career pivot and embarked on a Reimagine Journey to shift my focus from engineering leadership to hands-on technology. This extended leave gave me the opportunity to reflect on my passions and shape the next chapter of my career.

In August 2024, after an incredible 14-year journey at Intuit, I made the bittersweet decision to leave and pursue a life focusing on personal growth, learning and building tech solutions to real-life problems without the constraints of a full-time job.

Technical Expertise

• Agentic coding - building full projects with AI coding agents like Claude Code, Codex, and Gemini CLI, with a focus on crafting effective specs, context, and workflows
• Building web applications using modern web technologies like Next.js, React, Tailwind, TypeScript, and advanced JavaScript
• Developing mobile apps using mobile technologies like iOS, Android, Swift and Kotlin

Current Focus

As a hands-on tech enthusiast, I’m expanding my skills by:

• Mastering Agentic AI using coding agents and context engineering practices
• Teaching the basics of AI, its capabilities and risks to people in the community
• Building web applications for open-source and personal use

Projects

Each of these projects pushed me further along the agentic coding spectrum - from writing all the code myself to steering AI agents as a coach:

• KeepSeek - Mostly hand-written code; used Claude in the browser to troubleshoot and tweak UI
• Daily Bits - Built with Astro using a template; started doing chat-style coding for some features
• BeastMode - A fitness tracker built through Copilot AI in VS Code - mostly ask mode, some agent mode
• Pomodoro Flow - First fully vibe-coded app. Prompt, accept, iterate
• Travelogue - A private app for friends from a Himalayan trek. Let AI take the driver’s seat - a turning point
• HN Companion - Steady-state agentic coding with planned features, Linear tracking, and code review throughout
• annjose.com - My personal website migrated from Hugo to Astro, built entirely with Claude Code using spec-driven development

Beyond Technology

Outside of technology, two areas of passion for me are Math and Music which complement my technical side and keep me inspired. I learn Math from Math Academy and MIT OCW. I learn and practice piano during my free time.
