My work focuses on Ruby on Rails, PostgreSQL, APIs, and service-oriented architectures, with a strong emphasis on performance, reliability, and maintainability. In recent years, I have specialized in AI systems engineering, including RAG systems, MCP servers, AI product integrations, prompt orchestration, semantic search, embeddings, and LLM workflow design. I have led engineering efforts across healthcare, eCommerce, media, and international SaaS products, delivering MVPs quickly, modernizing legacy systems, and improving operational efficiency. I enjoy building practical AI-enabled tools that solve real business problems, especially where automation, search, retrieval, and decision support can create measurable impact. I am open to global remote opportunities and prefer working with teams that value technical depth, product thinking, and high-quality engineering execution. ## Skills ### [SQL](https://jobicy.com/talent/sql.md)[AWS](https://jobicy.com/talent/aws.md)[Docker](https://jobicy.com/talent/docker.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[GCP](https://jobicy.com/talent/gcp.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[GraphQL](https://jobicy.com/talent/graphql.md)[Distributed Systems](https://jobicy.com/talent/distributed-systems.md)[Redis](https://jobicy.com/talent/redis.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[Performance Optimization](https://jobicy.com/talent/performance-optimization.md)[Observability](https://jobicy.com/talent/observability.md)[Ecommerce](https://jobicy.com/talent/ecommerce.md)[Technical Leadership](https://jobicy.com/talent/technical-leadership.md)[Ruby on Rails](https://jobicy.com/talent/ruby-on-rails.md)[Vue.Js](https://jobicy.com/talent/vue-js.md)[Test Driven Development](https://jobicy.com/talent/test-driven-development.md)[Service Oriented Architecture](https://jobicy.com/talent/service-oriented-architecture.md)[Sidekiq](https://jobicy.com/talent/sidekiq.md)[Embeddings](https://jobicy.com/talent/embeddings.md)[Semantic Search](https://jobicy.com/talent/semantic-search.md)[Product Architecture](https://jobicy.com/talent/product-architecture.md)[Stimulus](https://jobicy.com/talent/stimulus.md)[Legacy System Modernization](https://jobicy.com/talent/legacy-system-modernization.md)[Healthcare APIs](https://jobicy.com/talent/healthcare-apis.md)[RAG](https://jobicy.com/talent/rag.md) ## Experience Senior Engineer, Founder @ Dasig Solutions, Inc.
