Online sourcing marketplaces (OSMs) enable the hiring of skilled workers around the globe. It becomes a significant factor for the increasing recognition of online sourcing as an alternative outsourcing option. Despite the adoption of individuals and small and medium enterprises, there is a dearth of study that looks into the service providers (workers) in OSM. This paper addresses this gap by exploring the experiences of online workers from the Philippines, particularly software developers engaged in independent online work. Findings found at least six themes prevalent to online software developers (OSDs) including uncertainty and transitions, trust and work agreements, reputation and client relationships, accomplishing tasks, platforms and software support, and work practices. The study suggests that by looking at the experiences of software developers, current and future clients (employers) can gain insights in considering this outsourcing option. Moreover, OSMs can consider the needs of OSDs presented in this study as inputs in customizing their services.
