As full time contractor developed a Node/react based web dashboard front end
(Web UI) for a software build accelerator cluster (Red Hat Linux).
• The app represents an "SPA" (Single Page Application) where widgets are laid out in a grid
based dashboard format with high responsiveness.
• The build system broadcasts progress messages over ActiveMQ which the Web UI
subscribes to.
• The web app visualizes system activity in realtime based on the traffic of incoming broadcast
messages, and runs database queries for statistics presentation and historical data access.
Developed six different React UI widgets that make up the dashboard graphics.
Widgets use a messaging bus for broadcasting messages to each other, to collectively present different aspects of the system progress.
Skills developed: Javascript ES6, npm, git/gerrit, Node.js scripts, React UI widget design, JSX
rendering syntax, Material Design, Elemental UI,HTML5/CSS, ActiveMQ, STOMP
protocol/websocket, httpd reverse proxy config with ssl tunneling, JSON/Rest, Insight database
(R-DS) aggregated queries, app deployment automation (build-from-git),
CentOS,RHEL,Ubuntu,OSX, Confluence/JIRA/Kanban, FixedDataTable-2 cell renderers..
Platform skills gained from the minimizing of client processor load (fine tuning of UI widget rendering and making database queries more efficient).
Was one member of a team of three developers + team lead, which developed the acceleration
system, each responsible for the full functionality of their part including its sw architecture,
choice of reusable components, customer open source compliance, installation procedure and testing.
Migrated the Node.js dev platform from v6 to v10 over that time.

Sweden
I founded medial.com (Swedish firm "MEDIAL Maskin & Data" org 580822-8539) back in 1992 as a small retail firm that for a short period operated sales/distribution of PC software.
During 2009 I reactivated this firm to operate a consumer online retail operation (http://medial.se)
as ISN code 47914 (online retail of consumer electronics). 90% of sales were ASUS laptops and all flavours of their novelty "Eee" series of compact computers that I sourced via the Swedish
importer. So I became skilled in the features of this product line. However dealing out products to consumers in a fierce price war market did not yield a sustainable margin. In summary a great
experience and insight in this trade, its ecosystem and how to set up and manage credit card
payment with the public and the logistics of product shipping.
Medial Maskin & Data proved successful in satisfying consumers. Medial often went the extra mile in terms of customer support and reached an impressive 8.3 out of 10 customer rating at the Prisjakt site in competition with the retail chain giants.

Technical support towards third party developers regarding Java development issues for Sony
Ericsson handsets, part of the Sony Ericsson Developer World activity. I worked on answering
tricky questions, authored and published application tutorials, stayed updated with new Java
related features in the latest OSE based phones developed. This job was in the midst of the stream of Java ME enabled products entering the market.
About 90% of the work was supporting mobile operator development partners
who developer the apps that becomes preloaded into operator branded handset models.
This position means direct encounters with just about all of the latest and upcoming Sony
Ericsson phone models from a support / application development perspective.
2006-07 - 2007-12
maintained SymbianOS/C++ module test code for quality assurance of SW modules part of smartphone core software (application platform). This was a great opportunity to learn the version
control/build system that was used for maintaning SymbianOS components in the large
smartphone sw projects. Module test was a discipline for verifying/assessing quality of to-be-
released firmware for SymbianOS based UIQ smartphones
(P990,M600,P1,W950,W960,G700/900)
2001-10 - 2006-07
I was Staff Engineer member of SymbianOS SW development team that developed the Application Platform SW for Symbian based smartphones.
I did development,Testing and Certification (TCK) work for Java runtime environment in Sony
Ericsson SymbianOS based phones.
I carried out this work for all Java enabled Smartphone models during the period
(P800,P900,P910i,P990,M600). This 'career' started out in an environment where I got to be
involved in a lot of simultaneous roles (authoring of pre-studies,requirement definition/mgmt for Java,test/certification) and, as the Smartphone organisation grew, specialised more on the sw
engineering side. Opportunity to practice development in Java and SymbianOS C++.
Development continued across successive SymbianOS incarnations, from version 7 to 9.1.
My main work role was integrating Java runtime environments for J2ME MIDP
1.0/2.0,PersonalJava,CDC/Personal Profile and made sure we passed TCK runs (Java VM certification) on the SymbianOS smartphones produced.
Annual intelligence gathering at U.S trade shows.
I was Technical Support Engineer towards Java contractor (IBM) for a J2ME CDC
implementation and authored that project's Assignment Specification.
2000-01 - 2002-09
I moved to the Ericsson mobile product organisation from Ericsson Radio in January 2000 to focus on architectural issues of Java technology in smartphones. During this time period my
Ericsson business card carried the title "Smartphone SW Architect". Java soon got postphoned to later products at the time (R380 era) and I moved into working as a staff engineer on prestudies for phones that became the Sony Ericsson P800.
1996-05 - 1999-12
presented to Ericsson Business Units. Strong focus on use of Java as development language.
Developer in OpenPhone research project (Java based handset platform featuring Marimba Castanet service deployment).
I represented Ericsson Radio as developer in an European research project (ACTS/OnTheMove) which developed middleware architectures and demonstration SW for UMTS mobile networks.
This included cooperation with researchers from several EU countries (I developed a Java based HTTP proxy solution for bandwidth/quality management). I co-authored a paper on UMTS
Middleware published in IEEE Mobile Communications Magazine and wrote parts of a paper for
a Korean wireless conference (MoMuc97). I was co-inventor of a patent.
Frequent travel and participation in many mobile industry conferences throughout Europe and the U.S as research engineer.
1990-05 - 1996-04
(Libra/Pegasus) used in 3G Phone exchanges.
The technology was very advanced at that time (RISC processor, Futurebus backplane, liquid cooling). System Design/Development/Debugging done in Assembler,C,C++.
In my spare time I proposed and implemented a more efficient document search/hyperlink tool for the company internal document database ("Attachment Tool") and was awarded 103 000 Skr at a
ceremony..
A major part of the time I worked on loan from Ericsson to Ellemtel. Actual Ellemtel employment
lasted only a month before the AXE-N project was discontinued. Former colleagues who were now in Kista told me to move there.
1980-10 - 1995-10
computer system (APN167) used in AXE phone exhanges. Equipment for the storage of debiting
data for phone traffic, built as rack magazine equipment (ROF/BYB). I developed a SASI adapter
board (EBA-SA), then worked in all disciplines of hardware product engineering when
developing a disk controller board for this I/O System, the infamous SCSI Mass Storage Adapter
board (MSA-SC) ROF1371802/1 that employed advanced LSI controller chips such as the National Semiconductor DP8466 Disk Data Controller and programmable array logic. I developed
from scratch the associated firmware (developed in PASCAL-E (an Ericsson derivative) and M68000 assembler). I gradually moved from hardware development to specialize on firmware
programming of communications processor boards (breathing life into the controller chips). I was
entitled Senior Systems Engineer.
