What I'm looking for

I’m looking to build AI-powered backends and semantic search in small, high-ownership teams—owning delivery end-to-end, collaborating closely with clients, and shipping reliable Rails systems on time within scope and budget.

I’m a Senior Rails engineer with nearly 10 years of production experience, specializing in AI-powered backends, LLM integration, and semantic search at scale. At Muller Medien Group (via Nearshore Portugal), I architect and lead development across multiple large-scale platforms—cutting API latency by 40% and improving classification precision by 60%+ by moving from keyword matching to embedding-based pipelines.

Since 2021, I’ve owned project delivery end-to-end as a Technical Project Lead—coordinating teams, setting timelines and milestones, tracking risks, running client meetings, and ensuring delivery within scope, budget, and time using Agile/Scrum and Kanban. Outside that work, I founded AMDS Software, where I design, build, and ship full-stack products end-to-end, thriving in small, high-ownership teams where backend craft and product-minded delivery both matter.
