Experience
My Experience
Southwest Airlines
Cloud Engineer
Designed and delivered a cloud governance and observability platform that identifies Lambda functions on deprecated runtimes across the entire organization. Architected a distributed serverless data pipeline processing 250,000+ Lambda functions across 1,000+ AWS accounts, 5 regions, and multiple environments — completing full analysis in under 4 minutes via multi-threaded collection. Built an event-driven pipeline using Lambda, S3, API Gateway, OpenSearch, and Terraform. Developed RESTful APIs and a React + TypeScript dashboard delivering KPIs and prioritized insights to both engineering teams and executive leadership. Implemented cloud networking automation using AWS IPAM and Python/Boto3, standardizing CIDR allocation across a multi-account environment aligned with FinOps practices.
Numaris
Software Engineer
Developed a cross-platform React Native app for secure Bluetooth control of Teltonika FMC130 units, replacing physical iButtons across 200K+ vehicles and reducing hardware costs at scale. Implemented MFA-enabled authentication with AWS Cognito ensuring reliable identity management across all mobile clients. Integrated with Zoho to automate account workflows via Lambda functions, improving operational response time and support scalability.
Dinoware
Senior Software Engineer
Led the architecture and delivery of a multi-tenant SaaS platform serving SME clients. Designed the React + Node.js frontend/backend with MongoDB, implemented CI/CD pipelines on AWS that reduced deployment time by 70%, and established TypeScript coding standards across the codebase. Drove sprint planning and technical decisions as the senior individual contributor.
ZF Group
Software Engineer Jr
Built a logistics optimization tool with Python and Google Maps API that cut monthly transportation costs by over $6,000 and streamlined operations for 200+ employees. Automated HR and Continuous Improvement workflows, compressing multi-day processes into minutes. Created internal Power Apps for job-role and food-service management, and a Django census platform that reduced data collection from 4 weeks to 2 hours.
Cinvestav RONIHM
Software Engineer
Architected and independently built an end-to-end data analysis system for police cadet driving assessments, transitioning from a Tauri/Rust desktop prototype to a high-performance ReactJS + NestJS system on AWS. Developed post-test analysis and visualization tools for vital metrics — stress levels, heart rate, acceleration — enabling data-driven decisions on cadet training progression.
Justia
Web Services Intern
Wrote Python automation scripts that reduced internal web publishing workflows from two weeks to two days. Led the on-site server to AWS migration of client websites with zero downtime throughout the transition. Contributed TypeScript-based SEO enhancements and integrated analytics tooling that improved organic search rankings for multiple client properties.
Cinvestav RONIHM
Research Intern
Developed a vision-based positional drift correction system for autonomous quadcopters operating indoors. Using OpenCV and C++, implemented real-time optical flow tracking backed by a neural network to detect and compensate mid-flight drift, significantly improving indoor navigation stability without GPS.
Ilumps
Software Engineer Jr
Contributed across four simultaneous products: (1) Zaturna — built scheduling dashboards for an event booking platform; (2) Vesvir — implemented AR overlays with TensorFlow and migrated the app from Ionic to native Java + AR Foundation; (3) Medical Imaging System — handled DICOM file storage on AWS S3 with React-based role auth; (4) Nexum — QA and e-signature features using Firebase.
