Background

About

About

Bridging clinical expertise and software engineering to deliver AI solutions for medical teams. Expert in designing reliable systems that handle complex healthcare data, incorporating clinical context aware retrieval augmented generation (RAG), multi-format data integration, and autonomous generative AI systems. Led the optimization of essential microservices through modern cloud architecture, transforming prototypes into fault-tolerant, auto-scaled secure systems with real-time data streaming for doctor-facing tools. Used firsthand medical experience (surgery, diagnostics, patient care) to shape solutions that fit clinical needs, from operating room workflows to long-term patient monitoring.

Work Experience

Work Experience

  • R&D Lead, DevOps and RAG Backend developer, Pendium Health

    Jan, 2023 - Present

    Authored and deployed Python-based infrastructure code across core AWS services serving as foundation for RAG systems for healthcare startups and auto-scaled FastAPI streaming architecture. Led cloud migration from monolithic scripts to Dockerized microservices on AWS.

    • Developed RAG systems for healthcare startups, boosting retrieval accuracy by 40% via custom retrieval agents (Chain of Abstraction, llamaindex).

    • Built auto-scaled FastAPI streaming architecture supporting 2k+ daily requests with <200ms latency and 98% uptime (AWS ELB).

    • Led cloud migration from monolithic scripts to Dockerized microservices on AWS (EC2, ECR, ELB, R53), integrating TLS termination and GitHub Actions CI/CD pipelines.

    • Achieved 90% reduction in deployment downtime via container orchestration.

    • Accelerated release cycles (12 hours → 10 mins) through automated build-test-deploy workflows.

    • Implemented zero-touch certificate renewal using AWS Certificate Manager (ACM).

  • Doctor of Medicine, CCSS Costa Rica

    Jan, 2024 - Dec, 20241 year

    Comprehensive care in-hospital and outpatient settings: surgical preparation, interdisciplinary consultations, and studies.

    • Family Medicine (Alajuelita Clinic): Management of chronic diseases (HTN, DM, dyslipidemia).

    • Gynecology (Marcial Fallas Clinic): Sterilizations, high-risk prenatal care, Pap smears, and basic fetal ultrasound.

    • Calderón Guardia Hospital: Rotations in Urology and Surgical Emergencies, preoperative preparation for lithotripsies, cholecystectomies, and colectomies.

    • Calderón Guardia Hospital, Internal Medicine: Management of medical emergencies (BPNC, cellulitis, renal/cardiac failure, coronary syndromes, CVA, TBI).

    • Calderón Guardia Hospital, Cardiology: Stabilization of patients with coronary syndromes and arrhythmias.

    • Calderón Guardia Hospital, Nephrology: Management of chronic renal failure and dialysis complications (sepsis, peritonitis).

    • Pediatrics (Max Peralta Hospital): Management of pediatric emergencies (seizure crises, dehydration, asthma attacks).

Projects Experience

Projects Experience

  • G-LAMP IoT Prototype

    Jan, 2017 - Dec, 20171 year

    IoT prototype designed for the Intel Innovation Fest.

    • Intel Innovation Fest 2017 Finalist

  • TAI

    Jan, 2022 - Dec, 202211 months

    Small project that hosted a local speech-to-text model with a Flask frontend and router port forwarding. Allowed classmates to upload MP4 recordings of medicine lectures and receive transcribed, organized notes.

    • Self-hosted speech-to-text pipeline

    • Used Flask for frontend and upload management

    • Delivered structured notes from lecture videos
