Professional Experience
-
AI Engineer at ARCOS LLC
- Delivered the company's MCP platform on a scalable AWS AgentCore Gateway architecture, giving customers and employees secure AI access to ARCOS systems. New MCP servers reuse its shared authentication and observability.
- Architected an OpenTelemetry observability foundation for agentic features and MCP servers, routing GenAI and MCP tool-call traces from all environments through an OTel Collector to self-hosted Langfuse for end-to-end agent visibility.
- Built an evals framework that scores agentic features with deterministic trajectory assertions and LLM-as-a-judge grading, and connected the scores to the same self-hosted Langfuse instance.
- Established a shared context repository with 50+ artifacts (architecture decisions, learnings, roadmaps, domain knowledge) used by product, engineering and AI agents, resulting in aligned roadmaps, faster onboarding and more accurate AI-generated work.
- Led agentic workflow best practices for 20+ engineers and product managers by applying context engineering and harness engineering.
- Accelerated team delivery by 80% by pioneering agentic coding workflows with subagents, skills and MCP servers, resulting in faster feature cycles and measurably higher output quality.
-
Full Stack Developer at Oracle
- Reduced log source retrieval latency by 40% by introducing Redis hierarchical cache and lazy loading of nested properties.
- Increased log source ingestion throughput by 35% by refactoring Spring Boot pipelines to leverage asynchronous execution and JDBC batch operations.
- Optimized page load time by 80% by implementing deferred loading strategies and asynchronous API handling.
- Reduced unit test runtime by 95% by introducing a UI-independent testing approach.
- Integrated React components into an MVVM architecture, developing reusable implementations adopted across multiple OCI services.
- Conducted testing for all added features, including unit, integration and end-to-end tests.
-
Full Stack Developer at GE Aerospace
- Implemented Java algorithms that reduced employee quality-metrics tracking time by 50%.
- Improved REST API performance by ~60% by integrating Elasticsearch, enabling faster and more efficient data retrieval.
- Contributed to microservices-based development using Spring Boot and Node.js.
- Created and managed ETL processes to centralize data into a data warehouse.
