Vetted ROI analysis developer in Brazil (UTC-3)

I'm an Engineer, with a background in Artificial Intelligence, and I've always sought to use technology to solve problems. In my Master's, my study focused on Artificial Neural Networks, and I've published scientific articles and produced a dissertation on the subject. In the last four years, I've dedicated myself to studying Data Science (Python, ML, SQL, Spark). I'm responsible and a team worker. During my career, I've taken on several managerial roles, having even led remote teams. I know how to work with other people and try to treat everyone with respect and courtesy. I'm always open to hearing suggestions, criticisms, and other perspectives. I have just finished the Data Science Bootcamp with the french school Le Wagon. It was an amazing experience and I was able to further consolidate my skills in Data Science: statistics and probability, SQL, Python (Pandas, Numpy, Sklearn, PyTorch, Tensorflow/Keras), NLP, MLOPs basics (Google Cloud). I am searching for new challenges and experiences, and I believe I can make valuable contributions.

Vetted ROI analysis developer in Brazil (UTC-3)

I have a Bachelor’s in Computer Science, a Master’s Degree in Data Visualization, and a double Ph.D. in Machine Learning The latter was a research focused on Time Series Forecasting and performed in partnership with the University of São Paulo (Brazil) and Rijksuniversiteit Groningen (the Netherlands). Since my Ph.D. in 2020, I have worked on several projects as a Data Scientist for fintechs and telecommunication companies. Despite being mostly a Scientist, I am also used to performing Engenieer’s ETL as I am generally involved in early production steps such as client conversation and data retrieval to match project demands. My last model achieved a KS of 0.67 and remained stable in production with PSI under 0.1. I am also excited to increase my experience with LLM and always be ahead on state-of-art methods. As a curiosity, I like to swim and have siblings in Madrid. I go to Spain when possible and can speak Spanish if necessary.

FAQs

Why hire a ROI analysis developer?

In today’s world, most companies have code-based needs that require developers to help build and maintain. For instance, if your business has a website or an app, you’ll need to keep it updated to ensure you continue to provide positive user experiences. At times, you may even need to revamp your website or app. This is where hiring a developer becomes crucial.

Depending on the stage and scale of your product and services, you may need to hire a ROI analysis developer, multiple engineers, or even a full remote developer team to help keep your business running. If you’re a startup or a company running a website, your product will likely grow out of its original skeletal structure. Hiring full-time remote ROI analysis developers can help keep your website up-to-date.

How do I write a ROI analysis developer job description?

Writing a good ROI analysis developer job description is crucial in helping you hire ROI analysis developers that your company needs. A job description’s key elements include a clear job title, a brief company overview, a summary of the role, the required duties and responsibilities, and necessary and preferred experience. To attract top talent, it's also helpful to list other perks and benefits, such as flexible hours and health coverage.

Crafting a compelling job title is critical as it's the first thing that job seekers see. It should offer enough information to grab their attention and include details on the seniority level, type, and area or sub-field of the position.

Your company description should succinctly outline what makes your company unique to compete with other potential employers. The role summary for your remote ROI analysis developer should be concise and read like an elevator pitch for the position, while the duties and responsibilities should be outlined using bullet points that cover daily activities, tech stacks, tools, and processes used.
