Certsys Tech Stack

IT consulting focused on digital transformation for Brazilian public sector

IT Services and IT Consulting Barueri - SP, SP 51–200 employees Founded 2007 Privately Held

Certsys pivoted to focus exclusively on government clients in 2023, shifting from generalist IT services toward public-sector modernization. The tech stack reflects enterprise Java and legacy integration work—Spring, Struts, ServiceNow, IBM Integration Bus—grounded in brownfield projects. Active hiring skews junior-to-mid engineering roles; pain points cluster around monolith migration and incomplete agile adoption, signaling an org still scaling internal delivery discipline while managing client transformation mandates.
