Marco Rojas

Senior Software Development Engineer

• Mobile technical lead for iOS and Android delivery: owned user stories, backlog refinement, sprint planning, retrospectives, pull request reviews, and cross-functional release execution with product and design.

• Led React Native platform upgrades in production, including enterprise Figma design token adoption, migration to the Fabric renderer, and phased Flow-to-TypeScript migration.

• Improved production stability so session crash rate fell from 18% to 0.2% through monitoring, targeted fixes, hardening, and careful release planning.

• Defined system architecture and led a cross-functional initiative to add wearables to clinical trial workflows, from discovery and solution design to implementation, production rollout, and support for study teams.

• Contributed to open source in React Native Health, implementing Apple HealthKit atrial fibrillation (AFib) support from API design and implementation through release and partner integration.

Software Engineer

• Built and ran an integration engine moving data for 800k+ patients across vendors and pharmaceutical clients on Node.js and AWS, owning architecture, on-call reliability, and day-two operations.

• Led a refactor and test automation push for remote ingestion pipelines (JavaScript, SFTP, AWS S3, PGP, mapping, reporting), reducing time to stand up a new integration by about 75%.

• Ran cutover and hypercare for a 200k+ patient migration (demographics through enrollments) on MongoDB and JavaScript, coordinating stakeholders, validation, and post-go-live fixes.

• Owned fifteen HIPAA-regulated integrations end to end, from requirements and implementation through deployment and production support for PHI exchanged with external partners.

• Shipped nurse-facing Vue.js workflow templates and event-driven microservices for clinical programs: wrote specs, trained users, and iterated from real-world production feedback.

System Administrator

• Containerized faculty web services using Docker.

• Configured OpenStack to provide Linux VPS infrastructure as a service for faculty projects.

Software Developer

• End-to-end owner of a React Native iOS/Android app for store distribution and fraud control, from UX and APIs through store submission; outcomes included a reported 99% drop in fraud and a 20% revenue increase.

• Built order, customer, payment, inventory, and routing features on a REST API, and integrated Bluetooth label and receipt printers, cutting order time by about 80% and delivery time by about 40%.

Lead Software Engineer

• Led a five-person squad to create an app based on a food engineering thesis research, collaborating with the Chemistry faculty.

• Developed a colorimetric analysis algorithm with a team of food engineers to determine fruits' degree of maturity according to federal standards.

Software Engineer Mentor

• Mentors cohort engineers on full-stack delivery with Node.js, MongoDB, React, and Express.js: problem framing, incremental design, implementation, deployment, and demo-ready polish.

Software Development Instructor

• Ran an "Intro to Docker" series, environment setup, image basics, and a capstone where participants containerized and shipped a small web app.

• Ran "Intro to Python AI" labs where attendees built and deployed a Markov-chain bot using the Twitter API and ethically sourced scraped data, from notebook to runnable service.

Software Engineer Local Leader

• Organized Node.js, Git, and front-end tracks for 300+ learners: recurring sessions, hands-on exercises that shipped small features, logistics, materials, and retrospectives.
