Introduction
I’m a Technical Product Manager and former CTO with 7+ years of experience building and scaling digital products from 0→1 to production. I’ve worked across AI/LLMs, mobile, backend and cloud infrastructure, and I’m usually at my best when the problem is still a bit messy: understanding the need, structuring the roadmap, making the right technical trade-offs and getting the product shipped. At HelloBible, I helped grow the product to 200K+ downloads, 50K MAU and 10K+ DAU, while building and managing engineering and AI research teams. I also have a strong customer-facing and commercial background, including selling to publicly listed companies such as Warner Music Group.
