The most amazing...
...thing I've developed is a Python package to automate a whole line of machine learning model generation for virtual analyzers.
Work Experience
Full-stack Developer
Esss
- Developed a web application with Angular (TypeScript) and Python (FastAPI) applied to reservoir engineering.
- Set up the environment, considering pre-commits and integration with Jenkins for CI/CD.
- Developed the front end with Angular based on PrimeNG. Contributed to an internal library of components.
- Created all models, serializers, and schemas to work properly with the FastAPI environment.
- Implemented all back-end and front-end tests, ensuring 100% coverage.
Senior Python Developer
AGULHA NO CELEIRO IMÓVEIS LTDA ME
- Developed a web app with Django, consuming a third-party API.
- Created a database updated daily using Heroku Cronn jobs.
- Generated tables, graphs, and insights correlated to a large amount of data.
- Built front-end with Django templates, bootstrap, HTMX, and Vanilla Javascript.
Project Automation Engineer
Petrobras
- Managed the consistency between databases of different engineering design automation tools by developing SQL and PL/SQL queries to read and write to MySQL and Oracle databases.
- Architected and developed software to automatically generate engineering reports using third-party API for queries to relational and encrypted databases.
- Updated the module of a legacy system from C# to Django while consulting extensive configuration files in XML and JSON.
- Developed command line software to monitor the reports generation, including logging and file management in case of memory problems.
Python Developer
Radix
- Developed and maintained a Python service to embed machine learning models in virtual machines using an OPC connection to get real-time data, make predictions based on it, and show results on a minute-by-minute basis on the operational dashboard.
- Created a Python package to abstract a complete automation pipeline from data synchronization, building the needed structures to deploy machine learning models.
- Advanced virtual online analyzer modeling to predict polymer physicochemical properties during production based on process measurements, such as temperature, pressure, and flow rate.
- Treated data from several points of process instrumentation to synchronize it with lab data since the acquisition frequencies are different.
- Applied interpolation techniques to fill in data and validate the model.
- Implemented a classification model to determine which polymer grade is being produced and which regression model to use.
- Applied model balancing techniques to predict out-of-spec property ranges since most data gathered from the plant and used to train the model is in spec.
- Integrated the regressor with a plant monitoring system to broadcast the model results to the plant operators and allow real-time decisions instead of waiting several hours for lab analysis.
- Developed internal APIs using Python and Django rest framework to avoid data decentralization.
