Daniel Carter

Cloud certifications

Daniel covers the cloud certification ladders — AWS, Google Cloud and the Microsoft Azure role-based track — for Exampractice. He writes the exam guides, the version-change explainers and the "which one first" pieces, and spends most of his editing time on the same question: does the credential still test what the job actually needs?

Sofia Martinez

Project management

Sofia covers project, programme and service management: PMP and CAPM, PRINCE2, the Scrum credentials and ITIL. She tracks the exam content outlines closely, because this is the corner of the catalogue where a syllabus change quietly invalidates half the study guides on the internet.

Alexander Novak

Cybersecurity

Alexander writes the security certification guides — CISSP, CISM, CISA, Security+, CEH, OSCP and the GIAC family. He is most interested in the gap between what a security exam certifies and what a security job asks for on the first day, and says so when a credential is mostly reputation.

Maya Patel

Data and AI

Maya covers data and AI credentials: data engineering, analytics and BI, the database tracks, and the fast-moving set of AI certifications. She is deliberately sceptical about the newest of them, and separates the ones that are proctored exams from the ones that are course-completion certificates wearing the same word.

Liam Anderson

IT and networking

Liam covers the ground most people start on: CompTIA and Cisco, from a first help-desk credential through to expert-level networking. He writes the beginner guides and the honest difficulty assessments, and is the reason those pages give a study sequence rather than a reading list.

Elena Rossi

Careers and salaries

Elena writes about what certifications do once you hold one — how they read to recruiters, where they move pay and where they do not. She sources salary context to named, dated surveys and will leave a number out entirely rather than repeat a figure whose origin nobody can trace.

Kenji Nakamura

DevOps and Linux

Kenji covers Kubernetes, Red Hat, Linux and the wider DevOps toolchain — which is to say most of the performance-based exams in the catalogue. His guides lean hard on the difference between exams you can read for and exams you have to practise for, because these are firmly the second kind.

Amara Okafor

Exam preparation

Amara writes the preparation methodology: study planning, revision technique, how to read practice-test results and what to do in the last fortnight. Her pieces are built on evidence about how people actually retain material, and on the unglamorous finding that most failures are pacing problems rather than knowledge gaps.

Lucas Müller

Enterprise platforms

Lucas covers the vendor ecosystems — Salesforce, Oracle, SAP, Adobe and the specialist awarding bodies. These are the tracks where exam codes churn fastest, so his guides date themselves clearly and point at the live catalogue rather than pretending a code will still be current next year.

Aisha Rahman

Costs, renewal and comparisons

Aisha writes about the parts of certification that cost money after the exam: fees, vouchers, retake rules, renewal cycles and continuing-education requirements. She also handles the head-to-head comparisons, on the view that choosing between two credentials is mostly an argument about total cost and recognition.
