I am a self-taught engineer with a passion for data and machine learning, and I have honed my skills through professional experience and formal education, including a Data Science certification from DataCamp and a course at Stanford University on Artificial Intelligence in Healthcare. Outside of my career, I actively participate in projects on platforms like Kaggle and GitHub to further hone my expertise. My main goal is to combine my IT knowledge with my background in biology to uncover new insights and drive transformational change at the intersection of technology and life sciences.

Data Analytics EngineerIdc Feb 2023 - Oct 2024As a Data Analytics Engineer, I am part of a internal project where I orchestrate the continuous flow of data from multiple sources (internal and external). My expertise goes beyond traditional data management techniques as I use advanced methodologies such as linear programming, along with tools such as Snowflake and Python, to optimize data workflows. Within this framework, I perform a range of operations including extraction, transformation, cleansing and complex data analysis, culminating in the derivation of measurable metrics.In addition, my responsibilities extend to working with business analysts to ensure alignment between data insights and organizational goals. This includes day-to-day communication and creation of solution documents to streamline processes and improve decision making.An integral aspect of my role involves project expansion, where I integrate additional attributes from internal modules and external sources. Leveraging API calls, I adeptly retrieve data in JSON format, enriching our dataset with diverse insights.In our quest for efficiency and effectiveness, we have explored the integration of machine learning and artificial intelligence solutions into our workflows. In experimenting with ML/AI, we have sought to automate processes. -
