· Participated in initial migration from a monolithical architecture to a microservices-based one. This allowed to scale our system from supporting hundreds to tens of thousands of users. Designed three of the main architecture domains: analytics, shipping and legal, and built them completely from scratch. · Part of the initial development team that built the product that lead us to getting accepted by YCombinator. · Designed, reviewed and oversaw implementation of multiple proposals for improvements in our architecture or creation of new features for our core product that added value for our users · Built +50% of our backend’s codebase, being the main contributor for it. · Continuously refactored our codebase, in order to set better practi

· Built code/infrastructure to scrape public sources to retrieve information with scheduling or on-demand, using AWS Lambdas. · Developed functions to label the recognized text in a document for specific countries and their documents. Participated in development of a Neural Network to improve labeling precision, and proposed a change to the existing architecture to include this NN as one of the steps of the Document Recognition process. · Designed the architecture and leaded the implementation of a fallback system to react upon failure of one of the OCR systems used, to significantly increase availability of our Document Recognition product.
