Hello! I am Jonathan Fink. Software Engineer, Leader and Innovator.
An engineer by trade, and also by hobby. I've been building cool things my whole life, and professionally as a software engineer for 23 years.
June 2014 - Present
- Service Mesh developed by Akamai incorporating Envoy proxy, Hashicorp Vault, and Hashicorp Consul on Akamai Linode compute instances.
- Implemented a mechanism for secure delivery and rotation of certificates and secrets using Hashicorp Vault.
- Hashicorp Terraform and Ansible used for orchestrating new deployments
- Hyper scale messaging service, Utilized C++ front end to implement a distributed, scalable MQTT messaging service. Apache Cassandra backend, Apache Kafka for distributed message passing.
- Testing it, at scale, was nearly as difficult as developing it. Utilized Akamai CloudTest initially for performance testing and evaluation. Later, led a team of third party contractors to develop a purpose built test tool for MQTT using Locust. Each of these tools utilized AWS EC2 instances, later added support for Azure.
- Developed another suite of performance testing tools using AWS Lambda, to quickly generate highly elastic load scenarios.

- Backend scalability improvements (python, nginx, gunicorn)
- A-B testing and evaluation using Headspin (www.headspin.io) to measure performance improvements using MAP
- https://github.com/aka-embu/aka-map
- Product Architect for Mobile video delivery and caching solution for embedded applications - Video on a wireless router, single board computer etc.
- Demonstrated at Mobile World Congress 2016 and National Association of Broadcasters (NAB) 2017.
- Python based, using Predictive Content Delivery backend.
- Mobile app and SDK to allow predictive caching of video content on an end user’s device. (TikTok before TikTok was a thing)
- Python backend, Postgresql DB. Video content crawlers written in Perl and Python.

August 2013 - June 2014
- Startup working on TCP optimizations to speed throughput on mobile and wifi networks
- Utilized data from Wireshark and tcpdump to create visualizations of throughput improvements and inter-packet latencies using python, numpy, matplotlib.
- Developed KPI’s for evaluating performance improvements
January 2001 - August 2013
- Embedded software and hardware diagnostics on various carrier-class routers.
- Perl, sh, TCL, python, and custom scripting languages. Embedded Linux, vxWorks, and custom runtime executives • Building custom toolchains using BuildRoot • CVS, git, Clearcase, Perforce, and subversion revision control • Windriver Workbench, ICE, and ICE2 for on-chip debug. • C, C++, Perl, Tcl, Python, sh, assembly
1997 - 2000

Cumulative GPA 3.5
VP Engineering
I have worked with Jon for almost 12 years. He is an extraordinary architect/developer and is easily in the top 1% of engineers I have led. Since joining Akamai, he has been promoted 3 times in a small number of years. Literally, any problem I have given him, he has solved and solved it quickly. This includes skunk works projects which were things being done on the side in addition to his main responsibilities. The more I have loaded Jon, the more he exceeds. While I have pushed Jon to do more and more over the years, I have not yet found where is limitations are. Further, Jon works very well with others and is highly respected leader. Jon is the guy you want on your team when your back is against the wall.
Mixed Signal Embedded Systems Engineeer
Jon has been an invaluable resource for the development of the Ericsson SSR platform. From initial board bring up and debug, to developing production testing and managing any issue in the production line Jon has always been the go to person.
