Ernesto Gutierrez Corona

OBJECTIVETo fully collaborate in a multicultural and multidisciplinary team with vision for Information Technologies enhancement inboth software and hardware components. Specifically, in Artificial Intelligence, Natural Language Processing, MachineLearning, Data Mining, Web Mining, Information Visualization and Data Visualization fields. Nevertheless, open and willingto explore related areas.

WORK EXPERIENCE

Software Engineer

• Working at Google Mexico via EPAM• Software development in Python• Software testing

Research Assistant & Software Engineer

Project: iCluster is an innovation and entrepreneurship ecosystem to facilitate and optimize entailment amongstakeholders of government, academia and private industry, and their contact with the market through the use of trustedsocio-economic data, expert working groups, regional innovation clusters, and smart specialization strategies, focusing onthe entrepreneur, businesses, and end users.

Team Size: QA: 3 members

Project Role: Quality Assurance Engineer

As Quality Assurance Engineer:

• I coordinate User Experience (UX) and Usability tests; I apply several methodologies to tackle a wide range of possibleenhancements.

• I coordinate User Interface (UI) redesign according to end user feedback; I conduct statistical analysis over UX andUsability tests results

• I perform manual functional testing to plan future tests

• I elaborate detailed and data-based change requests

• I coordinate the analysis of new requirements

Project: Sentiment Analysis API: Development of a sentiment analysis API for the processing of streams of short texts,written in both Python and Scala languages

Team Size: Dev Team: 3 Engineers QA: 1 Engineer

Project Role: Key Developer

As Key Developer:

I design, develop and test a sentiment analysis API in Python

• I design the RESTful API to be implemented in Django

• I develop the lexical-syntactical analysis module that extracts features from short texts; I work all phases of dataprocessing: cleaning, preprocessing and feature extraction

• I develop the module that automates model creation; I apply Support Vector Machines and Naïve Bayes classifieraccording to specific criteria

• I perform manual functional testing

I design, develop and test a sentiment analysis API in Scala

• I design the RESTful API to be implemented with Play Framework

• I develop the lexical-syntactical analysis module that extracts features from short texts; I work all phases of dataprocessing: cleaning, preprocessing and feature extraction

• I develop the module for stream processing due to the nature of the data (streams of texts)

• I develop the module that automates model creation; I implement an algorithm that merges results from a heuristicclassifier into a supervised-learning classifier (Support Vector Machines)

• I develop a module to establish non-blocking connection with MongoDB


Project: Content Semantic Analysis: Analysis of texts for the construction of a socio-semantic graph and the developmentof a recommender engine based on graph centralities

Team Size: Dev Team: 4 members QA: 1 member

Project Role: Developer

As a developer:

I construct a social-semantic graph based on demographics and analysis of text retrieved from objects or interest.

• I develop the lexical-syntactical analysis module

• I use lexical-syntactical module to extract features from textual resources and I relate them to nodes that constitutes thegraph

• I implement okapi bm25 algorithm to weight graph edges

• I participate in the design of the core algorithm for the recommendation engine
