- Co-founder
As the founding team’s sole engineer, I took two product lines from concept to real-world use on one shared platform: a B2B agency platform and a B2C consumer product. I took end-to-end technical ownership, from architecture through implementation and operations.
I designed and built the core agent system, the learning and memory architecture, in-house retrieval with no third-party embedding APIs in the loop, server-enforced multi-tenant isolation, the frontends, integrations and the full infrastructure. Expert corrections only become lasting knowledge after human approval. Every metric and chart a user sees is computed in code and audited. The model narrates results, it never invents them.
Both B2B and B2C approaches went through real user testing, from design-partner feedback rounds to early-user validation. If something shipped or broke on the technical side, it was mine.
