The most amazing...
...thing I've developed is an AI system for personalized behavioral health treatment. It was published in the IEEE journal. It won an honorable mention at ACM CHI.
Work Experience
Engineer | Quantum Applications
Womanium Quantum
- Worked confidentially for a US national research lab.
- Developed a suite of quantum applications that solve engineering problems using quantum technologies.
- Tested and deployed those quantum applications to a real quantum computer with more than 100 qubits.
Director | Data Science
PepsiCo
- Designed, fundraised for, and delivered three internal software products. Each product was measured and demonstrably increased brand reach and consumer product sales.
- Coordinated across data engineering, product management, marketing brand directors, and internal customer success managers to ensure smooth maintenance and operations of all three delivered software products.
- Restructured three geographically siloed teams and performance-managed them. Retention was 90% throughout the restructuring and stayed at that level throughout my engagement.
- Defined and hosted tech talks and tech demo presentations on an alternating biweekly cadence. Provided stakeholders with visibility into the individual contributors of my group. Ensured cross-functional collaboration with other groups.
Consultant | Artificial Intelligence
Antares Audio Technologies
- Designed, implemented, and deployed two deep learning sequence models. Both models leveraged state-of-the-art (SOTA) mechanisms, such as shift operations as replacements for convolutions and masked self-attention as replacements for recurrence.
- Ensured each of the two sequence models was interpretable and explainable to my two business stakeholders; the CMO and the COO.
- Coordinated with their software engineers how to integrate the two sequence models into their automated business processing pipelines.
- Coached the CMO and the COO on how to best consume the forecasts and the automatically generated explanations for their downstream automated business processes.
Director | Data Science
Booster
- Built their data team of four engineers. My team was horizontally integrated and served the needs of all other business units. My three business stakeholders were the CFO, the CMO, and the CPO.
- Oversaw the creation of the company's business intelligence queries and dashboards and managed its quality assurance.
- Participated in the design, implementation, and deployment of their demand forecasting systems for their B2B and B2C customer segments.
- Participated in the experimental design and analysis for pricing elasticity and demand response to pricing changes.
- Participated in the experimental design and analysis for marketing conversion and customer engagement with referral programs.
- Performed supply-side pricing analysis and informed executive stakeholders throughout multiple contract negotiations with Fortune 100 enterprises.
- Analyzed the quality and the efficiency gains of their proprietary vehicle routing software.
- Managed the data science support of their engineering efforts, including data modeling and analytics for their proprietary IoT platform.
Consultant | Artificial Intelligence
Stanford University
- Co-developed novel AI applications for personalized behavioral health treatments.
- Took part in the work that was published in the peer-reviewed IEEE scientific journal.
- Developed an AI system for personalized behavioral health treatment that was awarded an honorable mention in the peer-reviewed ACM CHI20 scientific conference.
Manager | Data Science
Autodesk
- Managed six machine learning engineers to create, deploy, and maintain three production systems in an Apache Spark powered data platform.
- Participated in the design, implementation, and deployment of their enterprise's customer churn rate forecaster.
- Contributed to the design, implementation, and deployment of the enterprise's sales recommendation system.
- Collaborated with the design, implementation, and deployment of the enterprise's software piracy detection system.
Consultant | Artificial Intelligence
Qubole
- Defined machine learning consulting offers for their B2B professional services division. My business' stakeholder was their senior vice president of professional services.
- Implemented, deployed, and marketed two deep learning solutions for drug discovery. These solutions helped them land their first contracts with publicly listed pharmaceutical companies.
- Improved their platform by demonstrating artificial intelligence solutions at large conferences, such as Strata and PyData.
- Worked on the platform by accurately predicting trends at the intersection of big data and AI and ML during interviews with CIO magazine and Forbes.
- Helped them win contracts with publicly listed banking and finance companies by providing deep learning and machine learning consultations with prospect clients.
Experience
Artificial Intelligence for Behavioral Therapy
https://www.stanforddaily.com/2019/10/21/researchers-work-on-device-to-help-individuals-with-autism-handle-stress/Our work was featured in Stanford magazine. Feel free to read the interview in the link provided.
Our work was also awarded at the peer-reviewed scientific conference ACM CHI20, and the US government granted us additional funding to continue our efforts.
Said grant money helped us develop the project further and subsequently publish in the peer-reviewed scientific journal IEEE.
