Professional Experience


Founder and President of L-Soft, the first company to develop and sell e-mail list management software in the world. Founded L-Soft with $3,000 and a laptop in order to further develop LISTSERV, the de facto standard of e-mail list management software. Expanded L-Soft from one person to a software company servicing thousands of customers from L-Soft's offices both in the United States and Europe.


Manager of EARN Services at SUNET (Swedish University Network), Stockholm, Sweden. Recruited from Switzerland to join a small team of handpicked experts tasked with making Sweden the leading Internet country in Europe. Jointly responsible for the Internet's core infrastructure in Sweden and, to a lesser extent, Finland, Denmark, Norway and Iceland. Sole responsibility (at age 23) for the "EARN Services," one of SUNET's five main service divisions at the time.


Senior Systems Programmer at CERN in Geneva, Switzerland (where the World Wide Web was invented). Responsible (at age 21) for an IBM mainframe serving 5,000 users and for a team of six junior programmers; joint responsibility for another six programmers. Developed the industry's first 12Mbps link between an IBM mainframe and a VAX located more than 6 miles away in the particle accelerator's underground facility.


Part-time Systems Programmer for the Ecole Centrale de Paris, a French university. In charge of an IBM mainframe (system maintenance, installation of new products and development of local software). Also trained a new Systems Programmer.


Audit at Fileca, a 350-employee company manufacturing high-technology cables. Suggested the implementation of an administrative data processing system to reduce costs and improve efficiency. Later tasked to write a high-level specification. Worked in a multidisciplinary team with the lead technical role.

Aug 1987

Traineeship at CERN in Geneva, Switzerland. Designed and implemented a network traffic monitor and improved network drivers with built-in data compression. This project led to a 30% bandwidth increase with unchanged costs.

Sep 1986

Traineeship at FCB Ivry near Paris. Developed PC software to compute and visualize the power consumption of a battery of sugar centrifuges (used to make sugar from molasses). The software made it easy to optimize the sequencing parameters of the centrifuges, which reduced peak power consumption and led to significant savings.


Created LISTSERV, the first e-mail list management software.


Designed and implemented (at age 15) an interactive programming and presentation language for the Palais de la Découverte (a science museum in Paris). Running on an IBM mainframe, the program controlled the terminals open to the museum's visitors and displayed a series of interactive menus and exercises to introduce the public to rudimentary data processing and game theory. Later tasked with the development of the bulk of the educational contents shown to the visitors.
