Summary: Line Manger and Technical Lead. Developing a greenfield, Netflix-like IPTV product.  
Distributed system architecture. Microservices (C#, ASP.NET Web API, MVC, REST API, kafka, Cassandra,  
DynamoDB) ,UX development (JS/TS/JQuery),Azure/AWS  
15 developer reports, 2 teams. My role was 70% hands on technical, 30% management  
I was part of the leadership team that transitioned Ericsson from a waterfall development structure to an  
agile scrum structure using industry best practice combined engineering, feature teams, CI/CD and devops.  
And away from Microsoft technologies and towards open source  
First team: 7 developers  
Developed a single page application (SPA) web app in Javascript and Typescript using React/Backbone  
as the framework.  
Underscore, JQuery, REST, HTML, CSS  
Second team: 8 developers  
Devops running and developing an in production C# cloud (Azure/AWS) hosted service (ASP.NET)  
I led the technical effort to migrate this service from a team in the UK to the team in Dublin.  
Due to changing business   environment I had to complete this move successfully in only 6 weeks  
instead of the planned 6 months. It was business / mission critical that I succeeded in the 6  
week timeframe (the UK office was closing). It was the “Ingestion” service - allows new content  
(movies etc) to be added (uploaded / transcoded / encrypted / packaged)  into the platform.  
Architecture: As much smarts as possible pushed into the cloud. Some logic running client side  
in the SPA. Kafka based message queues. Moved to a microservices based architecture  
Team: Three week sprints, sprint planning, daily standups, user story grooming and retrospectives.  
JIRA, Confluence, Gitlab, Slack  
Weekly 1:1’s with my reports, annual goal setting, annual reviews, career development.  
Coaching of reports  
Attended program level sprint review meetings every 3 weeks to review progress at an  
organisational level. Attended weekly leaders meetings to discuss issues and plan as well as  
planning overall quarterly and yearly strategy. Attended leadership offsites and training

Summary: Hard to summarise. We achieved unicorn status. I was employee #99 and the first  
technical hire in Europe  
I have extensive experience of MongoDB - of production deployments and cluster administration  
and of developing applications that run against MongoDB and also knowledge of schema design and performance  
If you called or emailed MongoDB in 2012 while NY were offline you came through to me.  
I was MongoDB worldwide support. When Eliot (CEO MongoDB) went offline at around 2am UK time, there was  
no MongoDB support until I came online at about 6am.

Summary: Developing an embedded linux VOIP product in C and C++. Linux driver development. Hacking in assembly. 
Linux kernel hacking. Working in agile but with in house hardware team working in waterfall  
Developed embedded wireless router that could also handle VOIP calls. It ran an embedded linux kernel (2.6.20)  
on an ARM architecture microcontroller (MIPS24KEc) from Infineon (Danube)  
Worked in C in the linux kernel. I wrote low level device drivers for the DSP and ISDN chips.  
There were some interesting moments in assembly  
I also worked in C++ at application level to implement the telephony functions  
In my first few days they told me trying to get the required performance out of the chip was a huge problem.  
They had both a team of software engineers and a team of hardware engineers working on it -  
on my 11th day there I pointed out a solution to this - that the chip they were using was in fact dual core.  
They were using it as a single core and could compile their linux kernel to use the second core

Developed an advanced service monitor for GPRS packet data networks. Multithreaded C++ application which ran  
on a dedicated multi-cpu server. It was sold to major telecom companies and monitored traffic on  
their GPRS data network. 
It “sniffed” packets from the wire and analysed those packets using a network protocol stack. 
The process worked at approaching line speed (10Gbs).
