Lulëzim Peci was the executive director of KCSF in the years 1999-2003, taking over the management of the organization in the period immediately after the end of the war in Kosovo in June 1999.

Together with Agon Demjah and Stephen Sampson, Lulëzim was one of three people who registered the organization on 2 December 1999, prompting it to begin intensive work in support of the non-governmental sector. This was the period when NGOs became the most important local channel for international support for overcoming the state of emergency and reconstruction, while KCSF was identified and supported by the European Union as the main local organization for the management of EU funds for civil society in Kosovo. During the period of his leadership, with the help of the EU, KCSF created mechanisms for awarding grants and distributed over 2 million Euros through more than 200 grants to non-governmental organizations in Kosovo. Also, KCSF started the first studies and publications on civil society in Kosovo, a basic training program for NGOs, as well as awarding over 400 scholarships for pupils and students of Roma, Ashkali and Egyptian communities.

Lulzim left KCSF in November 2003, when he led the spin-off process of KCSF programs, establishing the Kosovo Institute for Research and Policy Development KIPRED and became the first executive director of KIPRED.

He graduated in electrical engineering from the University of Prishtina, Lulëzim holds an MA in international relations from the Ortega i Gasset University in Spain, and a PHD in political science from the University of Southeast Europe in North Macedonia.
