The eight stacks, in order
HighCircl's nearshore bench, and most EU nearshore engineering shops in general, cluster around eight stacks: React, Node.js, Python, iOS, Android, Flutter, Go, and DevOps. Android coverage includes Kotlin as the language most engineers actually write in day to day, but Go remains the separate backend and infrastructure line, not a stand-in for it. For HighCircl's own stack-by-stack rate bands, see HighCircl's rates.
Where coverage holds up, and where it depends on the vendor
React, Node, and Python engineers are common across the EU nearshore market, along with iOS and Android mobile talent. Depth on the less mainstream lines, DevOps, Go, and Flutter, tracks with how selective a vendor's vetting actually is. Lemon.io is a useful data point here, based on reported buyer experience: strong on JavaScript and Python, thinner on specialist mobile, niche cloud, and less common backend languages. See HighCircl's Lemon.io alternatives comparison for the fuller picture. That gap is exactly why asking a vendor to show bench depth in your specific stack matters more than reading a rate card.
The geography behind the stack list
HighCircl sources these engineers from Poland, Hungary, Slovakia, Slovenia, Romania, and Spain, all EU member states, plus Serbia, an EU candidate country. Every engineer goes through a four-stage vetting process run by senior engineers, which is easier to hold to a high bar across eight defined stacks than across an open-ended list of technologies.
