A career timeline built from the work history available for this profile.
Frontend: Vue, Vuetify, Apollo-GraphQL, Cypress, TypescriptBackend: Python, Graphene, GraphQL, REST, asyncio, machine learning (pytorch, pytorch lightening, optuna), scraping websites.Other: XML, Github Actions, military background, TDDWorked with a few other software developers to develop a prototype military logistics website.
Worked on heuristic algorithms to solve NP-hard hardware related problems, and implemented them into a product using good software development practices.Software improvements:o Python: Improved adherence to PEP8 and google code style standards by providing support on code linting and establishing a PR checklist.o Git: Streamlined internal squash-rebase workflow by creating a training video.o Automated parallelization by using Ray on GCP (Google Cloud Platform).o Introduced joblib to cache intermediate results.Algorithmic contributions:o Invented a new data structure and algorithm to substantially improve the space complexity and meaningfully improve the time complexity of a core part of our program.o Invented a simple polynomial algorithm for an anticipated NP-hard problem.o Originated several ideas that changed our approach and resulted in an (~20%) improvement in the quality of our program’s output, in contrast to previous incremental improvements (~2%).o Provided counterexamples to quickly move on from algorithmic dead-ends.
