So, who am I?
I'm a passionate Senior Software Developer with great emphasis on macOS application development, and a strong background in Java and LAMP Backends, Web Frontends, Java Desktop Apps, System Administration and Databases. I always put my love in what I do. I'm positive, open-minded and determined. I'm always looking for personal and professional self-improvement, looking for greater and bigger challenges, and for great opportunities of sharing and learning with the best.
I really love what I do, and people seem to love too! It all started when I self-learned and explored the BASIC programming language on the old ZX Spectrum 48K when I was 8yr old. Since then, I become tech-savvy and later graduated in Computer Science back in 2001. I have acquired many experience in different areas (Backends, Frontends, Desktop Apps, System Administration,...) and worked in many different business sectors (Software, Telecommunications, Electronics, Higher Education and Healthcare) so I easily adapt to new technologies, company contexts and cultures. I am self-disciplined and self-organized, and my entrepreneurial spirit led me to start my own business twice. Collaborating with the Sakai Community greatly improved my team work and communication skills as I really enjoy participating on distributed teams. Being part of the Paw remote team allowed me to improve my collaborative competencies and mature my developer knowledge. Over the years, I have worked on many different projects, some of them (e.g., ThemeKit, Paw, Flavours) became highly engaging and popular among the community (check these great reviews about Flavours)!
I like to meditate in nature, surfing when the swell is great, and hanging out with my family and friends. I believe productivity is greatly increased when we are positive, open-minded, humble and determined. Pursuing mind-body-spirit equilibrium is key to wellness.

Flavours 2 Lite
Homepage: flavours.interacto.net
Flavours 2 Lite is an application to change the look of the Mac, and is bundled with a collection of 128 themes for OS X Yosemite.
Flavours 2 is the successor of Flavours Classic (1.x). It was designed and built from the ground up for OS X Yosemite, features a completely rethought User Experience through an elegant UI, and introduces a new lightweight, fast and safe theming engine.
It was built using Xcode 6 and mainly coded in Objective-C (with ARC) and C. It consists of a Mac desktop application, a status bar application, a privileged helper tool, a XPC service and a dynamic library for code injection. This development was particularly complex as it required a lot of OS X reverse-engineering.
The Complete Version (not released), just like in Flavours Classic, would feature a redesigned powerful editor with live-preview, the ability to share and download themes from the online Flavours Store, a theme change scheduler, and some additional features. However, Apple announced that the next OS X version - OS X El Capitan (10.11) - introduces a new security policy ("System Integrity Protection") preventing every process (even privileged ones) from modifying system files, either on filesystem or dynamically at runtime. Although this can be disabled by booting the machine into Recovery Mode and changing the setting there, this is not something that an average user would normally do, and we could not reasonably ask customers to turn off security protections. With those security restrictions in place, the Flavours project sustainability was seriously compromised, and so we were forced to halt further development. As a result, Flavours 2 Lite was released - bundled with a hand picked fine selection of themes - so that our users could still benefit from theming on OS X Yosemite.
Flavours Classic
Homepage: flavours-classic.interacto.net
Flavours Classic is an application to change the look of the Mac. It allows users to create, apply and share themes. Flavours Classic (1.x) is the predecessor of Flavours 2, and runs on OS X 10.7, 10.9 and 10.9.
Flavours Classic interacts with the Flavours Store using a RESTful API, allowing users who created their own theme, to share with the community. Currently, there are more than 1600 themes available online.
It was built using Xcode 5 and mainly coded in Objective-C (with GC) and C. It consists of a Mac desktop application, a background running agent, a privileged helper tool and an OSAX library (Scripting Addition) for code injection. This development was particularly complex as it required a lot of OS X reverse-engineering.
Flavours received a lot of great feedback from our users, and had great 4-5 star reviews on paper magazines and some websites (MacFormat, MacLife, MacWorld, etc)!
Flavours Store
Homepage: store.interacto.net
Flavours Store is an online theme store for Flavours Classic. It allows to browse all themes submitted by user, view theme details, filter by tag, user or keyword, and rate and comment.
It can be accessed from within Flavours, using a RESTful web service API, or using a web browser. It was built using Coda and coded using PHP, Mustache templates, MySQL, HTML, CSS and javascript. Themes are served from CDN servers for speeding up downloads.
jquery-i18n-properties
Homepage: github.com/jquery-i18n-properties
jQuery.i18n.properties is a lightweight jQuery plugin for providing internationalization to javascript from ‘.properties’ files, just like in Java Resource Bundles. It loads and parses resource bundles (.properties) based on provided language and country codes (ISO-639 and ISO-3166) or language reported by browser.
Resource bundles are ‘.properties‘ files containing locale specific key-value pairs. The use of ‘.properties‘ files for translation is specially useful when sharing i18n files between Java and JavaScript projects. This plugin loads the default file (e.g., Messages.properties) first and then locale specific files (Messages_pt.properties, then Messages_pt_PT.properties), so that a default value is always available when there is no translation provided. Translation keys will be available to developer as javascript variables/functions (functions, if translated value contains substitutions (e.g., {0}) or as a map.
This project was originally created by me and published on Google Code. In 2014 it has been migrated to Github and received additional contributors which are now responsible for the project.
Features
- Use Java standard ‘.properties‘ files for translations
- Use standard ISO-639 for language code and ISO-3166 for country code
- Sequential loading of resource bundles from base language to user-specified/browser-specified so there is always a default value for an untranslated string (e.g.: msg.properties, msg_pt.properties, msg_pt_PT.properties)
- Use browser reported language if no language was specified
- Placeholder substitution in resource bundle strings (eg, msg_hello = Hello {0}!!)
- Suport for namespaces in keys (eg, com.company.msgs.hello = Hello!)
- Support for multi-line property values
- Resource bundle keys available as Javascript vars/functions or as a map
Check the website for additional information.
GitHub Profile
Homepage: github.com/nfgrilo
This is my GitHub profile. Honestly, it doesn't contain many things besides:
- jquery-i18n-properties: the JQuery internationalisation plugin.
- Codility: my solutions to Codility Lessons and Challenges (in Objective-C).
Projects I have contributed to Sakai are not listed on my GitHub profile (my contributions were to SVN repo which later moved to GitHub):
- Sakai SiteStats: homepage | source code
- Sakai NewsFeeds: homepage | code
- Sakai BigBlueButton: homepage | source code
- Sakai Synoptic Calendar: homepage | source code
- Sakai User Membership: homepage | source code
Hopefully, I will get more time soon to change this in the near future :)
UFP-UV Virtual University
Homepage: elearning.ufp.pt
