- Led a cross-functional team of 10 software engineers and data scientists, translating customer requirements into technical tasks and overseeing delivery across 17 interdependent repositories. - Directed and validated all code changes, ensuring operational stability of a software system deployed across 3 secure cloud environments. - Orchestrated quarterly release cycles, including documentation, packaging, compliance submission, and deployment, sustaining 2+ years of uninterrupted releases. - Expanded system capability from detecting 2 to 68 behaviors of interest, scaling throughput to analyze nearly 7,000 observations per second and storing 13B+ observations per year for reliable user analysis. - Spearheaded the successful migration from AWS GovCloud to a government PaaS, ensuring continuity of mission-critical operations, improved scalability, and cost efficiency.

- Directed multiple cross-functional teams (15 members) to automate recognition of compound behaviors of interest, enhancing Defense Enforcement Operators’ (DEOs) ability to detect and respond to threats in real time. - Mentored and developed junior engineers and analysts, fostering technical growth and preparing several for expanded responsibilities within the organization. - Coordinated priorities across engineering, data science, and operations teams, ensuring timely delivery of high-visibility capabilities under tight government deadlines. - Facilitated agile sprint planning informed by customer priorities and evolving project requirements, ensuring alignment between stakeholders and technical teams. - Increased system release cadence from 6 months to 1 month by streamlining processes and implementing continuous improvement practices.

- Led an engineering team whose work enabled the seizure of $35M+ in narcotics, directly supporting mission-critical national security operations. - Redesigned virtual cluster architecture to improve maintainability and configuration while boosting cost efficiency by eliminating underutilized components and applying FinOps practices. - Automated deployment of a complex information system with Terraform, ArgoCD, and Jenkins, reducing manual effort and increasing reliability of release cycles.

- Modernized a legacy software system by introducing AWS cloud compute, Docker containerization, infrastructure as code (IaC), and CI/CD pipelines, significantly improving scalability and maintainability. - Built and led a pipeline of early-career talent by interviewing, training, and coordinating several college interns, accelerating delivery on critical project needs. - Developed a scalable, multi-tenant cloud-based analytics platform (PaaS) capable of processing high-bandwidth, radar-derived kinematic streaming data across multiple domains. - Designed and implemented security compliance solutions aligned with NIST 800-53 controls, enabling the program to progress toward Authority to Operate (ATO).

- Built a Python-based predictive analytics application leveraging geospatial-temporal indexing and association rule mining to forecast rare national security events. - Engineered a system to identify persons of interest by applying frequent subgraph analysis on Neo4j graph databases and known association networks. - Designed and deployed a full-stack predictive analytics solution for insurance claims during a 36-hour hackathon, showcasing rapid prototyping and cross-disciplinary collaboration.

- Developed a full-stack web application using Django and D3 to manage, validate, and visualize configuration files for a world-class space ISR simulator. - Applied Agile Scrum methodologies as part of a 4-person team, improving collaboration and iterative delivery of software features.

- Conducted high-fidelity light-scattering simulations of 3D virtual meshes using a Multi-Sphere T-Matrix Algorithm on the University of Maryland High Performance Computing Cluster (HPCC). - Analyzed Cassini light curve spectroscopy data to determine radial size and porosity of surface particles on Saturnian satellites Rhea and Dione. - Tracked rotational light curve data of asteroid (16813) 1997 UT6 using an internet-controlled telescope, supporting observational astronomy research.

- Supported the Steam launch of VR game Snailiens, contributing across concept development, design, testing, and deployment. - Accelerated development workflows by implementing distributed ray processing for swarm-based light building. - Managed content version control and distribution through Perforce server administration and Steampipe integration.
