Software Development & Web Design in Sofia
Software development, web design and hosting for Sofia software companies, startups, banks and shops, delivered remotely from Bucharest in Bulgarian and English.
Sofia, with 1.21 million residents, is Bulgaria's capital and its main centre for software, outsourcing and startups. Offices cluster in Mladost, Business Park Sofia and along Tsarigradsko shose, while Sofia University and the Technical University feed the talent pool. Buyers compare vendors in Bulgarian and in English.
What a business in Sofia has to get right
Bulgaria adopted the euro on 1 January 2026, so shops, invoices and payment settings must work in euro. The Commission for Personal Data Protection (КЗЛД) enforces GDPR, and NIS2 duties follow Bulgarian cybersecurity law. Consumer sites should be fully available in Bulgarian.
