Full-stack engineer building AI agents and knowledge graphs, from research to commercial release
I am a founder, product owner, and full-stack builder focused on turning complex, unstructured real-world problems into scalable, production-grade software platforms.
As Founder and CEO of Intergalactic, I led the end-to-end development of a high-complexity SaaS platform spanning ERP, CRM, payments and operations. I personally designed the system architecture and wrote more than a million lines of production code, while owning product strategy, UX/UI, engineering execution, fundraising and company operations.
The platform scaled to more than 10,000 users, generated over $770K in GMV, and secured more than $1M in funding across venture capital, government R&D programmes and guarantee-backed financing.
I have collaborated with global organisations including Google, Microsoft, JP Morgan and UK-based accelerators, and have presented products at international demo days and major technology expos.
Now
I am building an ontology-driven coding agent on the Coding Agent team at Wrtn Technologies, and applying the knowledge-graph and retrieval design validated in Consilience to it.
