Ana is a problem solver that enjoys finding and fixing needs while supporting her team. As a data scientist with a Ph.D. in pure maths and a current obsession with MLOps, she experiences profound joy in projects such as commit passing CI/CD, BI investigation to understand the process to model, project demos, data versioning, and graphs. So far, Ana successfully trained and logged models, saw an abstract pure maths concept improving her model, and had her code dissected at a code review.

Work Experience
Principal Machine Learning Engineer
Quantori
- Studied AlphaFold, its technical details, usage options, deployment options, analytics, and evaluation methods to aid potential company clients in incorporating AlphaFold in their processes.
- Coached colleagues and helped manage project delivery.
- Consulted on the best R environment set up for data scientists.
Data Scientist (Full-time Contractor)
Caterpillar
- Joined the team in the middle of a fast-paced project five weeks before the end of the year and helped shape the project direction and deliverables to achieve them.
- Introduced novel NLP approaches to the team that improved problem-solving approaches.
- Hosted a talk on one of the packages to the company's wider team.
Lead Data Scientist (Part-time Contractor)
Supernova
- Directed data analysis to diagnose problems in the Georgian language chatbot prototype that the team was working on. As a result, we discovered problems and direct our efforts to the highest impact issue.
- Made a recommendation to switch to the Rasa open-source chatbot framework and facilitated the switch, which resulted in a drastic increase in chatbot performance.
- Recommended adjusting the chatbot data structure to be more ontology-based and facilitated the adjustment process, making it possible to effectively maintain and validate the data mode.
Senior Data Scientist | Data Scientist | Associate Data Scientist
Eliiza
- Developed an information extraction and document processing application that saved our client 30% of processing time. As a result, we received more work from this client, and our team developed a product offering based on this prototype.
- Managed and mentored two interns that joined my information extraction project for a few weeks.
- Conducted technical interviews and hired five of my team members, including our manager.
- Worked on a variety of client projects, delivering high-quality data science work while supporting the internal team with presales, recruitment, and mentorship work.
WebWork Research Assistant | Sessional Tutor
The University of Melbourne
- Developed algorithms to create "Calculus 2" online assignment content on WebWork using Perl and PG programming languages and maintained the content afterward.
- Led tutorials for various mathematics courses in the School of Mathematics and Statistics.
- Let tutorials for "Logic: Language and Information" at the School of Historical and Philosophical Studies.
Postdoctoral Fellow
Auburn University
- Developed course content such as lectures and assessment methods, delivered lectures, and analyzed students' performance. I lectured for six courses, including several large classes in analysis, probability, and statistics.
- Built novel research methodologies, recursive algorithms, and constructions, applying them to solving problems in analysis and topology.
- Studied the feasibility of past research methodologies and reformulated long-standing mathematical problems into ones that could be tackled with models and techniques, from graph theory to logic, model theory, set theory, analysis, and topology.
- Published one research paper and submitted two more.
- Hosted three invited talks—one of them a semi-plenary talk at a major annual conference in my research field—as well as four contributed conference talks. I also gave ten seminar talks in my home department.
Teaching Assistant
University of Pittsburgh
- Lectured and conducted recitations for mathematics courses.
- Conducted lab sessions for mathematics courses as part of my role.
- Organized student seminars within my research group and the department of mathematics and statistics.
Financial Risks Manager
Aldagi BCI
- Worked closely with reinsurers to perform data analysis and reporting to best address their goals. As a result, we closed the first reinsurance treaty for financial risks for the company.
- Collected, maintained, processed, and analyzed financial risks data. I also collaborated with the sales and legal teams of AldagiBCI to clarify business processes, identify reliable data sources, and collect high-quality data.
- Developed and implemented mathematical and statistical methods to model data and draw insights. I used numerical analysis methods to develop novel algorithms to compute the key indicators regarding risk exposure and management.
Experience
Information Extraction
Our application receives an image, sends it through an OCR component, processes the raw OCR output according to the insurance company's business logic, and prepopulates the claim form with all the fields—like price, service item, provider, and more.
The team consisted of a machine learning engineer—for deployment and integration—and myself as a data scientist— performing BI research, problem scoping, and solution design and implementation.
The solution achieved a 30% reduction in average handling time for human review of the claims.
Chatbot Scoping
I worked across several teams to achieve this, including security, cloud engineering, and customer service teams.
Coaching
The project was deployed on DataBricks with R.
Chatbot Evaluation Framework
I worked closely with the chatbot maintenance team to identify the best suitable solution.
