Project experience
| Client | IntelliFinder (telecoms, fiber-optic) |
| Project description | Code-review (with emphasis on security and stability) of the clients in-house developed task-management software which is specialized towards roll-out of fiber-optic networks. Main customer of the system is danish incumbent telecom TDC. My main responsibility was to coach IntelliFinders developers in the mindset and use of design-patterns and Test Driven Development. I also helped with refactoring of the codebase to support automated testcases, which were lacking. I reviewed incidence reports from TDC and proposed solutions. Finally, I developed a tool to map out the dependencies of the system and produce a pivot-table to give the CTO an overview of the codebase complexity and help identify trouble-spots in the codebase. |

| Client | Københavns Energi (utilities) |
| Project description | Emergency troubleshooting and stabilizing of K.E's TastSelvService website where electricity and gas consumers log in to report their meter readings for billing etc. This assignment had highest attention from management as the system was crashing multiple times a day under load. It turned out that the web-application never closed its database connections and thus ended up starving the database server of resources. I quickly identified the problem and patched the source code so that database connections were freed straight away. Relieved management and happy DBA's. K.E. then hired me to maintain the system. |

A system that could replace the use of ad-hoc Excel spreadsheets that were being shared over email without synchronisation of data. I delivered a system where portfolio managers could import their Excel sheets and the system sorted the data into a common database from where they can manage their client portfolios from anywhere, via a browser, always in sync. This solution was written in Java and based on the Wicket web-framework. We named it "PAM" (Portfolio Administration Module). |

| Role on project | Systemudvikler |
| Year | 2006 |
| Client | Bonnier Publications (media, publishing) |
| Project description | A customer acquisition system for Bonnier Magazine Publications. The system receives customer's sign-up for magazine offers via Bonnier's marketing campaign sites, screens them against various "bad customer" databases and handles online card payment. Once screened, the system queues the orders up for Bonnier's (slow) AS400 mainframe subscription server and also automatically notifies partner webservices of the order, so they can dispatch a prize or such. The system has a dashboard for the marketing dept. to track customer conversions and where they can follow the flow of each magazine order. Marketing partners can download lists of leads and report back sales status. Management wanted the system to be extremely speedy since the existing subscription system was failing under the load and losing potential customers. So much attention was given to optimizing for performance. The system interfaces with the "BonnierShop" which is the CMS behind the marketing campaign websites. In short: an online marketing platform. |

The security queue time is shown on screens around the airport so passengers can know what to expect when arriving at the security lines. The system is browser-based and offers a dashboard for security management to track security gate performance in realtime and also pull performance reports to show compliance with regulations. We also built a search engine for pulling security camera images for a given time range. |

| Role on project | Consultant |
| Year | 2005 |
| Client | Vinsprit koncernen (beverages) |
| Project description | Consolidation of all of Vinsprit's digital image archives. VinSprit is now part of Pernod Ricard. This assignment resulted in a new product. It was realized that the planned "Cumulus" image archive system was inadequate to implement the client specifications so we built a new digital image archive from scratch with multilingual product texts and conversion into many image formats. Marketing bureau's can log in and pull the images they need and in the resolution and image type they need. This off-loaded a lot of tedious work for VS. We imported all their product images (>10.000) and all the metadata into the system and they were ready to go. |

| Project description | ICH2 – numberportability, phase 2. This system is Telia's implementation of the Danish phone number portability strategy. When customers transfer between telecoms, they can keep their existing phone number(s). This system sends and receives messages to and from Operators Clearing House (OCH) — the national central phone-number registry — and updates Telia's backend systems when customer transfer (or "port") between telecom's. It's a state-engine that keeps track of the porting processes and has a dashboard for monitoring all the flows. I was deeply involved in the design of Telia's part of the system and was responsible for the core state-machine and interfaces to certain backend systems. |

| Client | Nordea (banking) |
| Project description | The PANDA project. This system generated full tax reports for large corporate clients. I was tasked with fixing a part of the system related to special investment funds. It turned out to be especially tricky, due to the unbelievable complexity of the financial instruments involved and the bank's top guy admitting that he could'nt explain them logically (in hindsight, I could have predicted the financial crash right then and there!). Three prior consultants had given up and left the project but I managed to pull it off and received a stuffed toy panda and eternal gratitude from the accounting dept. who were otherwise looking at months of additional work if I hadn't. |
