What I'm looking for

I’m looking to build secure, production-grade AI-powered SaaS—taking end-to-end ownership of architecture, integrations, queues, monitoring, and reliability—where accuracy, reviewability, and fast iteration in real systems matter.

I’m a Senior Software Engineer and Infrastructure Engineer with 9 years of experience building multi-tenant SaaS platforms, API-heavy products, and cloud infrastructure across LegalTech, AI content automation, FinTech lead generation, retail, booking, scraping, and agency-built software.

I take end-to-end ownership—turning product discovery and architecture decisions into implementation, deployment, monitoring, performance optimization, and iteration—especially in startup and agency environments where reliability, speed, and clarity both matter.

My recent work focuses on AI development and integration: RAG-style retrieval, LLM orchestration, document processing, structured extraction, semantic search, and secure AI workflows for law firms and content intelligence platforms. I design systems that keep user experiences responsive while long-running document workloads continue in the background.

Across my roles, I’ve built microservices and distributed systems with asynchronous processing, data pipelines, third-party integrations, and production operations on AWS, Azure, GCP, and Cloudflare. I’m particularly known for combining architecture, queue-based processing, observability, and security-conscious patterns to ship maintainable systems that teams can trust.
