I am a

astrophysicist ➡️ software engineer

🔭 I was an observational astronomer working in the field of galaxy evolution and dynamics, where I used the world's best telescopes to look deep into space, and back in time, to a time when galaxies were younger and and more violent than they are today.

⭐ By studying their galactic dust and gas heated by exploding stars and active black holes, I uncovered how galaxies use them to fuel their star formation.

👨‍💻 I applied my knowledge in both physics and astrophysics to create innovative computer vision and image processing algorithms for aerospace and maritime technology in industry.

🛰️ Now, I develop tools to empower fellow scientists and developers to explore the Earth at with Planet Labs' tiny satellites!

I primarily develop in Python, version controlling using git on GitHub & GitLab. I am currently learning C++, SQL, and web development! Below are the relative strengths for the languages and tools I use in my stack:

Python 100%
C++ 40%
bash 60%
git 80%
PostgreSQL 30%
