Experience
HERE Technologies
Timeline: 2018 - Present
Role: Software Engineer II
A member of a team dedicated to the alignment and synchronization of multiple data sources, such as
LIDAR, GIS Imagery, and sensor data for use and consumption by autonomous vehicles. The synchronized
data is combined and used into the production of a 3D Mapping platform used by various automobile
manufacturers.
- Experience in the Agile software development process.
- Worked with a large team of engineers to successfuly deliver multiple projects to critical stakeholders on time and with excellent results.
- Development of new algorithms and techniques to enhance both data alignment and updating of various input sources.
- Key role in implementing new algorithms to drastically reduce user-involvement in the generation of 3D maps for autonomous vehicles. Resulted in a reduction of direct user involvement in certain areas of the map by 70%.
- Successful in leading efforts to modernize and secure a large and old codebase. Efforts entailed things such as bringing the codebase to more modern C++ compilers, compiling on multiple newer Linux operating systems, improvements to SWIG JNI bindings for exposed C++ code to external consumers, and quality of life improvements such as enforcement of a clang-formatting policy to be used by over 30 software engineers.
- Critical role in the both creation of new Products and in the continued long-term Support of Products.
- Development of advanced user tooling in proprietary UI software using C#/C++.
- Development of software automation techniques for rapid deployment.
- Extensive use of the GoogleTest suite for both C++ and Java Unit Tests.

Timeline: 2016 - X
Status: Incomplete/Hiatus
Prototype for a Live web chat over web sockets with "groups" as seperate chat rooms with user customizability. Prototyped in Python, written in C with use of JS, Nginx, MySQL.
- Prototyped in Python, written in C.
- Multi-processing with communication queues to separate modules of the server and allow certain areas of the application to resize their process and thread counts to better handle server load.
- C classes written to manage specialized hash table of user and connection data in shared memory (System V IPC) for multi-processed server applications.
- JavaScript custom framework for the front end. Connected to the server through web sockets for client-server communication.
- Nginx for serving static content.
- MySQL used to store client data for persistent sessions and information.
- Tested to handle 150k concurrent users on a single quad-core Xeon 3.0 Ghz machine with 8Gb of RAM and 1Gb NIC.

Timeline: 2014 - April 2, 2016
Status: Terminated
Created a video streaming engine with ~15m unique visitors a month and ~200k-350k pageviews a day. Served high-bitrate 720p and 1080p encodes with a daily bandwidth usage of ~40TB, accumulating thousands of dollars a month for server costs. Most influential project. As the sole developer/owner, lead a team of 6+ people to provide constant uptime and server monitoring for stability and optimal streaming capabilities, as well as listen to user feedback for improvements.
- Use of Python, C, Bash, MySQL, PHP, JS, HTML5, CSS/SCSS
- Created a custom reusable PHP Framework with central registry, namespaces, class autoloading, and link handling, to name a few (same as rawranime).
- Created a custom reusable JavaScript Framework with asynchronous page loading, modular design, and OOP page binding. Compiled with Google Closure compiler with advanced optimizations enabled. Allowed for the use of dynamically loaded pages to be bound by JavaScript. (same as rawranime)
- Highly customized VideoJS HTML5 Player, compiled with Google Closure compiler and modularized for specific functionality that Arkvid provided.
- MySQL data backend, setup and optimized to support hundreds of requests per second across multiple processes.
- Python was used with bash and C to create a centralized server console that would distribute commands, updates, and auto-deploy new servers with minimal effort. Heavy use of multithreading for server handling and SSH connectivity. Specific algorithm developed in C to handle the server stress and distribute load between the network of servers.
- Git was used to create quick and easy distributions of back end server code to new servers and updates, with bash configuration scripts.
