About Andrew H.

OVERVIEW: Expert in Python with 10+ years of experience and fluent in writing efficient Python code using OOP, comprehensions, generators, context management, type annotations, and commonly used libraries such as asyncio, textwrap, itertools, and datetime. Passionate about open source and promoting reproducible research.LLM EXPERTISE: Extensively developed products based on LLMs; proficient in using OpenAI\'s API, local open-source models through LlamaCpp, and frameworks such as Marvin, Instructor, and LangChain. Applied RAG to enrich LLM outputs with context. Won first place at the Leaner Startups AI Hackathon by leveraging Google\'s Speech to Text for transcribing calls, which were then analyzed by OpenAI GPT-3.5 Turbo to identify potential scam calls, aiming to safeguard vulnerable communities.PYTHON PACKAGES: Extensive experience with prefect, pandas, xarray, matplotlib, holoviews, geoviews, hvplot, and panel, able to utilize the majority of these libraries effectively without referring to documentation. Skilled in using dask, numpy, metpy, and scipy, able to recall essential functions without assistance. Familiar with other libraries such as geopandas, rasterio, numba, datashader, selenium, django, and flask, and able to quickly refresh their capabilities as needed.EDUCATION: Bachelor\'s and Master\'s in atmospheric sciences with a focus on model comparison and verification; knowledgeable about various deterministic and probabilistic metrics such as RMSE and Brier score in addition to significance testing.OPTIMIZATION: Adept in optimizing code using techniques such as numpy vectorization, dask parallelization, numba compilation, and simple code cleanup and reordering. Has successfully reduced code runtime by 40 times through these methods.OPEN SOURCE: Contributed over 500 Pull Requests to multiple open source repositories, including prefect, holoviews, xskillscore, xarray, metpy, cartopy, geoviews, and panel. Experienced in using git, code linting, unit testing, and GitHub Actions in these contributions. Developed an open-source package for data animation named ahlive.FILE FORMATS: Capable of wrangling many data formats: plain binary, GRIB, HDF5, netCDF, GeoTIF, JSON, YAML, and csv. Worked with PostgreSQL, BigQuery, and sqlite databases.US Citizen
