Owned, maintained, and significantly improved the backend microservices that offer thousands of shipments to carriers and route hundreds of shipment schedules on Mothership's platform in real time. Migrated from Python monolith to event-driven TypeScript microservices built in NestJS. Python, Flask, TypeScript, Express, NestJS, Firebase, Postgres, Kafka, KubernetesVastly increased visibility of shipment risk for our operations team, increasing proactive customer engagements and reducing response time by owning Mothership's entire "Shipment ETA" strategy and implementation. Documented and socialized statistical (and actual) significance and presented results organization wide. Designed and deployed an event-driven microservice to provide real-time risk and ETA information for thousands of shipments flowing through the platform. TypeScript, Express, Kafka, Firebase, Postgres, Kubernetes.Improved visibility of shipment risk by developing, deploying, and fine-tuning neural network model to assess shipment risk based on real-time carrier features and shipment features. Documented and socialized statistical (and actual) significance of results. Python, ScikitLearn, Pandas, Numpy, Flask, Postgres, Kafka, Kubernetes.Owned strategy and implementation of data analysis to improve accuracy of "carrier arrival time" predictions to retain a critical customer and win expansion of services. Worked closely with sales and client to socialize results. Python, Pandas, Data Analysis, Postgres.

Worked as a senior backend engineer on a small, fierce team to replace existing React Native mobile app with native mobile applications iOS and Android in 6 months. Managed rollout and customer-driven improvements via analytics and feedback. TypeScript, Express.js, NestJS, Firebase, Postgres, Mixpanel, Kafka, KubernetesOwned, designed, and implemented the entire "carrier schedule" feature for the new mobile applications, an event-driven system for pushing suitable shipment opportunities as soon as they become available and providing real-time updates to each carrier's schedule, ensuring an efficient and serviceable route. Python, Flask, TypeScript, Express.js, NestJS, Firebase, Postgres, Kafka, KubernetesLed design, documentation, socialization/approval, and implementation of company-wide Segment service and SDK, standardizing our "wild west" of Segment events to adhere to best practices. Witnessed dramatic uptick in Segment usage by operations-- particularly, in surfacing as-of-yet-unreported shipment issues-- and sales/onboarding.

As tech lead, led team of 8 engineers and coordinated heavily with 4 other comparably sized teams to deliver a complete rebuild of company's monolithic transaction-processing system utilizing micro-service architecture. NodeJS, GraphQL, Google Cloud Platform, Postgres, Kubernetes.Increased uniformity of coding practices by leading and supporting a team of formerly Ruby on Rails developers to adopt NodeJS, allowing engineering resources to flow more freely between teams. (Ultimately, this made eventual augmentation efforts vastly more successful.) Owned the initial setup, deployment, and CI/CD pipelines for several NodeJS microservices using the NestJS framework. Helped ramp-up the team via documentation, run guides, best practices, and presentations. NodeJS, GraphQL, Google Cloud Platform, Kubernetes.Supported and maintained a critical, SOA payroll-processing application built with Python, NodeJS, and React, rapidly resolving issues and blockers so that large portion of the organization's payroll could be processed weekly. Python, Flask, NodeJS, React, Google App Engine, Postgres.Led a team of 3 engineers, a PM, and a designer to win the Workrise 2020 Hackathon, re-imagining Workrise's central "work capture" system. Project became the central initiative for my team in 2021H1.Served as the goto resource for ramping-up new engineers at all levels (senior, staff, principal engineers and tech fellows) on the company's core initiative. Served as primary resource for all augmentation efforts when my team fell behind schedule.Supported principal engineer and tech fellow in re-imagining Workrise's microservice domain boundaries and socializing it through the organization, helping to the lay the groundwork for Workrise's future architecture. Domain Driven Design, Event Driven Architecture.Established and led one the key teams in the company's central initiative for 2020. Received highest possible performance rating in 2020.

Designed, developed, and deployed, at-scale, the Pathways Mapping Toolkit(TM), a first-in-class web application that allows community college faculty and advisors to compute, validate and publish ideal academic plans for students based on transfer university requirements. (Technologies: Javascript/React, Bootstrap, Python/Flask/Scrapy, Bash/CentOS/Nginx/uWSGI, MySQL).Deepened "predictive analytics" practice in Institutional Research by developing: a "decision-tree model" to identify most accurate college-readiness placement factors; a "regression discontinuity study" to determine long-term impact of placing students into developmental education; a "Bayesian model" to quantify student dropout risk based on demographic information and historical course-taking performance; and "linear regression models" to predict enrollment patterns for allocation of institutional resources. (Technologies: Python/Pandas/Scikit-Learn/Matplotlib, Oracle)Operationalized survey data collected from 2009 - 2017 (11800 surveys with 218 questions) to discover how student experiences vary across racial and gender subgroups. Identified statistically significant (and actually significant) differences between racial/gender subgroups with regard to importance/usage of campus services, goals, and sources of attrition.Designed, developed and deployed ComplianceAssistMigrate, a suite of software utilities for migrating documents between ComplianceAssist software and other storage systems (a feature which is not supported by ComplianceAssist). Designed utilities for assembling and publishing (PDF) documents based on internal style guide. (Technologies: Python/Selenium)Redesigned several assessments of institutional effectiveness ("program review", "program outcomes assessment", etc.) to better operationalize data for decision support.Convinced literally everyone they can solve their problems with Python or Javascript. (Actually, still in progress...)

Instructional Redesign:Redesigned online mathematics instruction (in 2010), drastically improving rates of student success from ~30% to ~65%. Established best practices for online mathematics instruction that have been adopted across all three of our campuses. Developed three new online offerings: Technical Mathematics; Differential Equations; and Linear Algebra. Redesigned developmental (remedial) education, reducing the time required for students to complete entry-level mathematics coursework from 3 semesters to 1 semester, decreasing the cost to students by 2/3, and increasing student success in this pipeline from ~11% to ~70%. Co-created nationally recognized co-requisite remediation program at San Jacinto College. Presented nationally on reform work, including at League for Innovation; National Association of Developmental Education; and DREAM.Institutional Reform Work:Led college-wide task force spanning instruction, student services, and campus operations to create and pilot a fundamental redesign (SmartStart) of the entire student experience from college application to completion of first semester course. Increase both quality and quantity of credits attained by pilot group over the control group.Designed and developed scalable procedure for engaging non-mathematics faculty in selecting ideal entry-level mathematics course for degree programs that has since been deployed at other institutions and at the state level (in Arkansas).Board Work:Served as mathematics lead on numerous regional, statewide and national task forces to advance institutional reform, including: STAAR EOC Assessment Task Force; Gulf Coast PASS; Houston Pathways Initiative; Texas Success Initiative; Houston GPS; Texas Success Center HB5 Task Force; Gulf Coast STEM Accelerator; Texas Higher Education Coordinating Board; Texas Pathways Project; American Association of Community Colleges Faculty Advisory Council; AACC Pathways Project; Indiana Postsecondary Mathematics Task Force.
