Experience

Consultant / Freelance developer

Built a location-based money transfer platform in Django as a proof of concept for a finance startup to showcase their Open Banking APIs; the proof of concept was selected for the Central Europe Open Banking competition and won a special prize from Google.

Created business intelligence (BI) apps in Vue and Streamlit to explore natural language data, such as customer support logs and net promoter score forms, leading to substantial reprioritization of the client’s business.

Designed and developed an analytics and back testing app for trading stocks and options, decisive for choosing the main investment strategy of the client.

Developed Forex scripts and indicators for retail investors to help them generate consistent alpha for two months.

Designed and led the development of a speech processing system. My contributions directly led to deploying a functional system in three weeks for a team stuck in research and paper implementation for 6 months

Adore Me / Artificial Intelligence Engineer

Developed and deployed the company's first data-driven recommender system that is currently in production and makes around 15–20% of recommendations for operations worth around $120 million per year in revenue.

Created an aspect-based sentiment analysis algorithm to gather product preferences directly from clients' wishes and automatically integrate them into the recommender system.

Built a BI app on top of the aspect-based sentiment analysis algorithm to help product owners prioritize work by letting them mine and analyze submitted forms from clients, substantially changing the focus of two teams.

Developed a similarity and clustering color algorithm to find complementary products and comparable items when predicting the performance of to-be-launched garments.

Built a Google Calendar data analytics pipe to compute and monitor time spent in team meetings to identify harmful patterns and potential burnout for a few colleagues.

Projects

Parse Bank Statements

https://github.com/ouatu-ro/parse-bank-statement
Many Romanian banks currently do not export data in a friendly format, so parsing PDF bank statements is required. The project was about a simple script parsing bank statements for Raiffeisen and Alpha Bank. Every financial department can use it for easier auditing transactions made on company credit cards, saving 25 hours a year of error-prone work. I also use it to track my expenses.

Python Dependency Scripts

https://github.com/ouatu-ro/python-dep-scripts

This project provides terminal commands to facilitate some of the most challenging problems in the Python ecosystem, including Python version management, virtual environments, and dependencies. It ties together two other tools, pyenv, and Poetry. For more details, the README file in the GitHub repository reads as a tutorial and an article.

Covid Data Visualization

https://ouatu-ro-covid-data-viz-covid-bky2ls.streamlit.app/
This project aims to provide data regarding vaccination, variants, and notification rate to be easily seen and understood. The demo app offers many options, such as comparing data from multiple countries, selecting preferred plots for data visualization, and displaying the official PDFs from the European Centre for Disease Prevention and Control web page containing a data description.

Eletron Voice Cloning

A state-of-the-art (with regard to how natural the voice sounds) text-to-speech synthesis application for the Romanian language that can clone women's voices with less than one hour of speech. The cloned voice achieves a 4.47 +-.15 out of 5 naturalness score as measured by a medium human opinion score on the Likert scale compared to real voices' 4.80+-.14.
A direct comparison was made to the previous SotA and Google Translate Romanian voice. Over 90% of subjects find
Eletron to have a more natural voice, and 100% of subjects find it more natural than Google Translate voice. Eletron is based on the Tacotron model and trained using GCP resources and the SWARA dataset.
