Analyzing/coding/testing/documenting applications that use machine learning of digital images acquired in real time by tractor-pulled device to distinguish between crop plants and weeds in order to improve efficiency and sanitation of common operations (thinning, weeding, side dressing, fertilizer application) performed as part of growing lettuce and other vegetables, while using 90% less chemicals than more conventional practices. Supporting product sales, staff of agricultural service providers.

* modified existing libtorrent and uTorrent code bases

* coded multi-threaded core product in C++

* added features to open-source UI in HTML, CSS, Javascript

* wrote pre- and post-sales technical literature

* created tests: unit, system, platform evaluation, stress

* developed product release process

* created build/test system framework in Python using Amazon Web Services (EC2, S3), including

** product building using GNU make

** unit/system testing

** valgrind analysis

* provided technical support

Worked on somewhere between 40 and 60 different embedded devices to integrate the BitTorrent client with them.

Product profitable based on royalties minus expenses for me and part-time business manager.

Created developer wiki for product, trained manager and 4 engineers joining the department.

2) uTorrent Server for Linux

* developed all releases

* provided technical support in company web-based forum

3) BitTorrent/uTorrent for Android

* used standard Android tools (NDK, SDK) and Eclipse

4) Android/native embedded BitTorrent client for Internet media player with 10-foot remote control TV UI integrating Internet Archive contents via torrents

* designed/coded services used by front-end developers

5) Sync

* back-end/API C++ engineer, providing services to web UI developers

* RESTful-like API: co-designed, co-implemented, wrote system tests

* migrated embedded system test framework to work with Sync

* designed/coded embedded-related features

Developed software using Python and Cheetah

Financial analytic services startup licensing access to web-based HTML application running on Apache and Linux for Mozilla and IE browsers.

Participated in development of major release (2.3) and maintenance releases.

* Designed and implemented object-oriented application development/testing infrastructure in C++, including classes for strings, file/directory handling, exceptions, HTML generation, automated unit testing.

* Improved automated build system using make.

* Initiated practice of developing automated regression tests for all new features.

* Designed and implemented report engine that was more than twice as fast as the previous one.

* Implemented new UI design for main pages of application.

* Ported formerly-IE-only application to Mozilla.

* Worked with in-house domain experts to resolve ambiguities/conflicts in specifications.

* Installed and administered FreeBSD 4.x on my workstation.
