Senior Developer / Tech Lead
Confirm architectural decisions, mentoring of juniors and the ability to balance technical debt against delivery.
The CV says "Senior Developer" — but what does that actually mean? Technical roles need verification beyond the diploma: which stack was used productively, what role did the candidate have on the team, and did they deliver on estimates and quality?
In IT there is huge variation in what sits behind a job title. Reference checks for developers, DevOps engineers and tech leads are about confirming concrete skills, real ownership in projects and the ability to collaborate in a code community. Referansio lets you add technical questions per role and get structured answers you can compare across candidates.
Challenges
"React 5 years" on a CV can mean anything from writing two components to architectural ownership. References clarify actual depth.
Technical skills are only half the picture. How does the candidate handle code review, pair programming and architectural disagreement?
Was the candidate the lead on the project, or one of eight? Direct questions to former managers clarify actual role and responsibility.
For access to production and customer data you need trust. Reference checks document reliability and discretion.
Use cases
Confirm architectural decisions, mentoring of juniors and the ability to balance technical debt against delivery.
Verify uptime, on-call discipline, IaC experience (Terraform, Pulumi) and ability to handle production incidents.
Check collaboration with design, performance focus, accessibility and how the candidate balances pixel-perfect against development time.
Confirm pipeline experience, data quality discipline and whether the candidate has actually shipped models to production — not just notebooks.
Questions
Industry-specific questions you can use as a starting point — customize in Referansio.
Regulations
Technical reference checks fall under the same GDPR framework as other recruitment: legitimate interest or consent as legal basis, and data minimisation as a principle. Only ask about what is relevant to the role — not political views, health or religion. Avoid questions about specific clients or trade secrets the referee is bound by NDA on, and stay focused on the candidate's role, deliveries and collaboration. Referansio structures the questions so you stay within legal bounds without having to think about it per candidate.

From new candidate to finished report — without manual follow-up.
Enter the candidate's name, role and referees. Takes under two minutes.
Referees receive a simple questionnaire and respond securely on mobile.
