Married, 2 children. I have been developing web sites and custom tailored apps since mid-90s, working in many different programming languages and with quite a few CMSes and frameworks. Recently I have mosty used Django/Python for apps and larger websites and ModX/PHP for smaller websites. The other area of expertise is custom tailored Business Application Development.

Excel VBA Programmer

United States - Last active: 10/09/2014 - Tests: 1

Programming is my passion and Excel is one of my top programs that I love to automate. I have been working with Excel for over 10 years and can provide solutions in many areas. E.g., creating user forms for data input, creating templates for data processing, incorporate different data sources into a master file, input data from excel workbook into web browser (data entry automation), manipulate and normalize data sets, generate excel reports dynamically and more. I take pride in my work and look closely at details of a project and carefully debug my programs. I'm currently employed by the number one book publishing company in the world where I oversee an excel spreadsheet-based dashboard system that aggregates staff's time recorded in different time tool systems. I also created many excel vba scripts used for data processing and also python scripts with selenium web driver for web scraping.

iOS Developer

United States - Last active: 03/31/2014 - Tests: 4 - Portfolio: 1

After diving headfirst into the iOS SDK back in December of 2011 and coming out 1 week later with a simple Flashlight app that is now used by more than 300 people a day, I never looked back. I immediately fell in love with the possibilities mobile phone development brought to the table and have now built 3 iPhone apps of my own and worked for 2 mobile based startups, WhatsApp and Happier. My first internship was with WhatsApp Inc. during the summer of 2012. At WhatsApp I spent a lot of time working their in-house support and translation team to build an in house CMS for the support documents. Although I did not get to spend anytime working on their iPhone app, I spent nearly all of my non-work hours building joox.fm (http://joox.fm). A music app that aimed to make listening to music with friends more fun. From there I landed a 6 month internship at Happier Inc. where I worked one-on-one with their lead iOS dev to help build their premiere 1.0 Happier client and ship it to the App Store. After a huge demand for a Web and Android client, I started building Happier's webapp https://www.happier.com. I built happier.com from the ground up using cutting edge HTML5 technologies like localStorage, pushState and AppCache.
