I have 10 years of experience as a software engineer in a variety of contexts: web, applications, embedded, CI/CD & more. I am extremely good at learning new systems and technologies quickly. I thrive on building relationships with users and delivering value that makes a difference to them.
I am an expert at managing legacy code and technical debt, delivering value in the short term while also following best practices to manage the system in long-term, making future maintenance and development work easier, cheaper and more predictable.

This role comprised development of Continuous Integration and Continuous Delivery systems for the CM4, the
onboard computer of Scania and MAN's next generation connected vehicles. Here I implemented & optimized Conan
recipes and Gitlab pipelines that continuously build, package, integrate and test software, while ensuring legal
compliance with UNECE R155, etc. Serving over 200 developers, I provided them with keys to success: shortening
test and integration feedback loops from weeks to minutes, making challenging QNX ports of open source modules,
creating working guidelines & setting standards, as well as lending my general programming expertise to developers
when they got stuck. I coordinated with application teams, investigated development bottlenecks and designed new
ways of working that enabled teams with diverse needs to work effectively together. Clear and empathetic
communication, alongside high quality execution, were crucial to my success in guiding developers through
migrations away from legacy tools and processes and towards new tools and better ways of working. I authored and
carried out initiatives to raise quality and implemented automated testing and quality controls, e.g. Clang Sanitizers,
to eliminate classes of bugs, tidy code and reduce testing and maintenance costs. I helped in every way possible to
deliver the business-critical CM4 project before crucial deadlines, firstly with maintainable and future-proof solutions
and design, and secondly by responding creatively and effectively in times of crisis. I thoughtfully invested in my
team's growth, spending considerable time mentoring and teaching teammates about technologies, engineering values
and best practices; in workshops, spontaneous calls, and in code reviews.

Embedded Software Engineer
Net Insight AB
Working on the Nimbra Media Switch Router, a network device itself consisting of multiple distributed systems
with extremely high quality and stability requirements, I helped deliver a project overhauling the user account
system, bringing it in line with modern features and security standards. Later I made an impact fixing bugs,
making quality and stability improvements, and reducing technical debt. Using test harnesses to guarantee the safety of
my changes, I refactored several core modules and interfaces, empowering my colleagues to write cleaner, more
efficient code more quickly and with fewer bugs, resulting in less rework and reduced costs. I also contributed to a
more robust continuous integration pipeline, leveraging more automated tools to find defects more easily and earlier
in the software lifecycle, raising quality even further, reducing costs and redirecting developer effort towards higher
value-creating work. Lastly, I proposed, designed and executed a project to migrate the version control system to
standard git, removing a painpoint that had slowed all developers' work down for over 15 years.

Software Developer
Autotank/Gilbarco Veeder-Root
Creating smart, connected petrol stations I worked developing embedded systems, microservices and web
applications. I gathered and refined requirements for, and implemented from scratch, a microservice to collect and
upload transaction data from 1000s of petrol stations. I worked on a web application, revamping the module that
allowed customer operators to install firmware updates to all units in their entire estate of petrol stations, here I made
substantial improvements to user-experience and performance while working in the constraints of a legacy system.
My improvements were appreciated so much that I was assigned the task of optimizing several other webpages (and
the SQL queries behind them) to bring load times down from well over 30 seconds to fractions of a second.
Furthermore I helped out senior team members by solving long-standing bugs reported by users in legacy C++
embedded systems.

Embedded Firmware Engineer
Irisys Ltd
Working on the Irisys Vector, the next generation active infrared people counting device, I rose to the challenge and
delivered working software within the time and budget goals of a highly aggressive business plan, without
compromising requirements for performance, security, stability and real-time availability. I wrote software to run the
device's functions as well as firmware to control peripheral devices connected to the motherboard. I leveraged unit
testing to eliminate bugs, ensure correct behaviour and prove the robustness of the systems' error handling. I
enhanced our continuous integration pipelines to monitor code quality with static analysis tools and LLVM sanitizers,
which helped catch mistakes early and reduced costs caused by defects in testing and production environments. I
embraced continuous improvement, studied best practices and shared knowledge with my colleagues through book
recommendations, discussions, constructive code review feedback and active participation in Scrum sprint planning
and retrospective meetings.

Web Developer
Irisys Ltd
Working as a web developer for Irisys' Queue Management solution I developed a web application (Python/Django)
that connected to infrared people counting devices installed throughout supermarkets. The system provides store
managers with real-time data about the lengths of the checkout queues and gives predictive advice regarding the number
of open checkouts needed to meet upcoming demand, while meeting service level targets. I extended the application's
functionality to provide reports that aggregated statistics across 1000s of stores for the benefit of the senior management
of large supermarket chains. In this role I also overcame the challenge of carrying out legacy maintenance on related
desktop applications, such as a planning tool for the physical installation of the people counting devices.

I built a treebank (data for statistical language analysis in linguistic research) from manuscripts in Old Church
Slavonic language, analyzing the morphology and syntactic structure. I quickly mastered the annotation scheme and
was entrusted with reviewing colleagues' work. I exceeded expectations by using SQL to carry out consistency
checks across the corpus and by writing software and scripts to partially automate some tasks.
Skills acquired: SQL, C, shell script, sharp observation & analytical skills, written communication skills
