What I'm looking for

I seek challenging roles building scalable SaaS products where I can lead architecture, improve legacy systems, apply AI automation, and mentor teams within a results-driven, engineering-focused company.

I am a Senior Full-Stack Web Developer with over 15 years of experience delivering web solutions, specializing in the Laravel ecosystem, multi-tenant SaaS architectures, and end-to-end DevOps on AWS.

I have led product development and enterprise projects for clients including Ikea, Goodyear, Caterpillar, and Suzuki, built a multi-tenant Career Website Builder from concept to paying customers within 12 months, and created commercial products on marketplaces with strong sales traction.

I focus on code quality, performance optimization, security hardening, mentoring teams, and applying AI/automation (LLMs, embeddings, RAG, AI agents) to improve developer efficiency and product value.
