Engineering Leader & Full-Stack Architect
Leading engineering at two companies — building an ecosystem of 7 enterprise products (ERP, logistics, workforce platforms) with government system integrations, and serving as lead engineer at an industrial services company. Background in both software architecture and business operations (procurement, logistics, team management) gives me a systems-level view of products.
17 merged PRs in Svelte, SvelteKit, Biome, OXC (235k+ combined stars). Two production backends: 41K lines Go (ECS + Event Sourcing) and a B2B SaaS scoring 27K+ tenders with AI.
Server engine for creating digital twins of businesses. Entity-Component-System architecture with Event Sourcing — every business object is an Entity with typed JSONB Components, every mutation produces an Event in an append-only log.
