CTO & Co-founder of PiktID • Researcher-turned-founder • GenAI Engineer

I'm the co-founder and CTO of PiktID, where we build GenAI tools for image editing at scale. Our two products are Studio, an image-editing platform with 300K+ users, and On-Model, a fashion e-commerce SaaS used by 50+ brands. My PhD is in Deep Learning for Communications Engineering, with publications at NeurIPS and in IEEE Transactions. Day-to-day I own the full pipeline: research, model development, backend and API design, cloud infrastructure, and the product on top.
