Implement Odoo projects; Customize Odoo instances; Create Odoo modules; Extraction-Transformation-Load (ETL) operations.In these years, I've been involved in 3 major customizations, 3 implementations with minor customizations, and 5+ modules including 4 connectors to other systems, 2 of which are payment gateways. Project details are available from my GitHub profile https://github.com/AdanCortes/PortfolioMajor customizations: A candy distributor with wholesale and retail stores (El Descontón), a second-hand food processing and packaging machineries reseller (Regal Equipment) and a taxes-filling related service (Stark, see below); Minor customizations: A small grocery store (Bodega del Sazón), a small restaurant (Cocina del Gallo) and an e-commerce for quilt and patchwork templates (KunigoPat); Modules: A Mexican chart of accounts (l10n_mx_sat), Mexican electronic invoice generation (l10n_mx_sat_catalog); and 4 connectors: Two for Mexican electronic invoice stamping (diverza, finkok) and two to payment gateways (OpenPay and PayU).

Full stack developer with almost 20 years of experience: I'm a capable system administrator, being able to resolve server and networking issues; I can model real-world data and develop an appropriate database; I understand business logic, I had implemented a couple of instances of Enterprise Resource Planning software and wrote some modules myself; I have broad experience in programming, particularly Application Program Interfaces; I'm familiar with modern web technology to build user interfaces and with computer-human interaction techniques.I've implemented a couple instances of Odoo, a One-Time-Password Authentication Server (best known as second-factor authentication or token authentication) for a level III financial institution and software for oil stations that are Pemex franchises.These days, my software choices are: MacOS for desktop operating system; Ubuntu as server operating system, Python as general-purpose programming language, PostgreSQL for relational databases, Git for version control, VirtualBox for virtual environments during development, Emacs for text processing, Bash for shell programming, Odoo as enterprise resource planning software, R for statistics and Gnumeric as spreadsheet.Nevertheless, in past projects I have used: Pylons, C++, C, Delphi, and Visual Basic as programming languages; Windows as operating system; Jenkins for continuous integration; PHP, HTML, JavaScript, JQuery, CSS, Less, Qweb and Mako to develop web pages; ImageMagick, Gimp and CorelDraw! for basic image manipulation; Selenium, Taiko, and nose for unit testing; LaTeX for writing documentation and math formulae; MatLab and MySQL among other fine pieces of software. Currently, I'm self-studying Stanford's Andrew Ng CS229 (Machine Learning)
