- Hired and led a team of 9 devops engineers, data engineers, and data scientists to create a monitoring platform for the world's largest solar + storage installation. Resolved interdepartmental technical conflicts through focus groups and clear process documentation. Enhanced data ingestion by 500× through development of a Golang-based service, enabling real-time collection of 1M metrics/sec from 3,000+ modbus-based hardware devices on-site.- Architected a Python-based reporting platform to democratize data access for both technical and non-technical users. The platform applied an intuitive label system for easy realtime data retrieval and provided customizable templates for generating rich, customer-specific monthly reports.- Developed a hybrid edge-core architecture for VictoriaMetrics database in Kubernetes. This innovation facilitated real-time data collection at site and optimized data transmission over limited bandwidth links. Ensured robust data redundancy by synchronizing with a central database and data lake hosted in AWS.- Oversaw a Python enforcement service to track asset availability and battery cycle KPIs, ensuring equipment warranty compliance for a $1B project that powers Las Vegas, NV.- Orchestrated a Python service for optimized energy discharge scheduling, resulting in a 6× increase in revenue during Full Requirements Periods and crucial for managing stress and volatility in the Texas electrical grid.- Implemented PagerDuty for alerting and issue resolution and Grafana dashboards for efficient system monitoring and servicing.

- Directed full-stack application development as Team Lead and Principal developer for a 4-member team. Managed all phases from requirement analysis and system architecture to coding and deployment using React.js, Apollo GraphQL, Prisma, Express, Postgresql, and Docker. Key projects included: - Architected and developed a multi-channel alert app (web, email, SMS) for plant operators to signal peak power events, achieving cost savings of $40k per incident. - Designed and implemented a weekly recurring scheduler for managing the charging of 10,000+ battery cells across 57 sites, powering 1M+ US homes. - Designed a robust API for automated energy storage system control, which eliminated the need for manual round-the-clock remote monitoring. - Significantly improved a financial modeling app’s performance by developing a MERN (MongoDB, Express, React, Node) based replacement, cutting page load time from 4 sec to 0.2 sec.- Streamlined site commissioning by establishing configuration management and a CI/CD pipeline for Docker that facilitates building and deploying to Kubernetes, reducing software deployment time from 3 days to 2 hours.- Enhanced efficiency by dockerizing C control software, thereby enabling remote compiling and debugging while eliminating on-premises processes.

- With a team of three, enabled healthcare professionals to unobtrusively care for older adults and reduce nightly falls by creating a full-stack HIPAA-compliant dashboard that collects metrics via POST requests from a bed sensor.- Developed a dashboard in Angular.js and D3 to allow caregivers to monitor their patients at night.- Deployed web app to 2 assisted living facilities that serve 300 patients- software alerted caregivers to 34 falls in the first 3 months so they could provide immediate support.
