Bio

Lucas graduated as an aerospace engineer at Brazil’s most renowned engineering university (ITA). Since college he has worked on software development projects, starting at StoneCo Digital Bank and then as a data scientist at FieldPRO, an early-stage startup. At ITA, Lucas developed a strong background in math, physics, statistics, and software, all invaluable tools that helped him on his journey through tech.

Work Experience

Head of Data

2019 - PRESENT
FieldPRO
  • Collected field data and developed multivariate models to calibrate an IoT device, including rainfall and soil moisture measurements, using nonlinear models. More than 300 sensors have been delivered to date.
  • Designed and implemented the whole data processing infrastructure of the company from scratch, including ETLs using Python, Pandas, Celery, InfluxDB, and GCP.
  • Created APIs and visualization dashboards to provide data to final customers.
  • Developed yield models for soybean and sugarcane crops, using historical measures, climatic, soil, and satellite data.
  • Led projects for third-party data ingestion, including weather station measurements, weather forecasts, and satellite imagery.

Software Engineer

2018 - 2019
StoneCo
  • Developed a proof of concept for a registry for credit card receivables using Python and Django.
  • Designed and implemented a credit marketplace from scratch, using Elixir. The marketplace was intended to use a new regulatory structure created by the Central Bank of Brazil to match customer loan demands to credit providers.
  • Developed an end-to-end test switch to perform integration tests in an open banking API.
  • Created a debit card system, including integrations to other financial microservices and third-party infrastructure, using Elixir and Phoenix.

Experience

Multi-objective Optimization Based on Metaheuristic Methods Applied to a Satellite Orbit Project

https://github.com/LLatyki/centauri
This is a project written in Julia that I solely developed during my aerospace engineering graduation project. It used genetic algorithms to optimize the design of satellite orbits. To accomplish this objective, many satellite orbit simulations were performed using different families of orbital parameters and considered atmospheric drag, orbit perturbations, and satellite maneuvers. Each orbit simulation was assessed using metrics of propulsion budget and ground target revisit time. Finally, some multi-objective optimization decision methods were applied on the resulting Pareto frontier.
