Bio
Felipe Espósito
Hernan is one of the best engineers I had the pleasure to work with. He is someone you can always depend on to take the right architectural decisions and to build software with the highest robustness and quality standards. His attention to detail is impressive and he is super focused on the task at hand, delivering high quality results every time. It's been great working with him and I hope we can work together again in the future!
Pablo Gabriel Celayes
During our time working together, Hernán showed impressive problem solving and learning skills, always eager to move out of his comfort zone to push the project forward. He was not only a proficient web developer, but also didn't hesitate in changing hats and doing database, sysadmin and even some frontend work when it was so required. On top of all his technical excellence, Hernán was a fun and easygoing colleague, always open for collaboration and all in all making my time at Infoxel a very pleasant experience.

A project from Red Hat for the argentinean migrations agency that ingest huge amounts of data from different databases with different structures and merges them into a single model easily consumable by users that need to extract information / patterns / connections / events from that data. • Improved Elasticsearch indexing time by paralelizing the process with celery tasks, removing unnecessary queries and db indexes. • Refactored the “saved searches” feature to skip the postgres database and run a ES query instead, improving response time and reducing the amount of code. • Designed the “similarity search” feature to identify db rows that could be accidental duplicates or clones.

Kansas City startup (divvyhq.com) which builds a SPA platform to help marketing teams organize their campaigns and coordinate their content creation workflows. • Create django forms, views, models and data migrations, create API endpoints using Tastypie. • Refactored mocks and unit tests into integration tests. • Refactored and denormalized several models into a Postgresql’s table view that paid off lots of technical debt. • Designed the frontend architecture of the MarionetteJS SPA, to use controllers and dummy views and integration tests for views. • Debugged memory leaks from BackboneJS views. • In 2016, I relocated in Kansas City MO, USA for 6 months for a knowledge transfer programme, working from the client’s offices.
