I find the vulnerabilities in your web apps, APIs, and networks before attackers do, then hand your team a clear, reproducible penetration testing report they can act on. GXPN and GCIH certified. Top Rated on Upwork with 100% Job Success across web application, API, and network security engagements. No scanner dump and no jargon wall. Every finding comes with a severity rating (CVSS), working proof of concept, and a concrete fix your developers can ship. What I test: - Web application penetration testing (OWASP Top 10, PTES, NIST) - API security testing (REST, GraphQL, auth/OAuth, IDOR, broken access control) - SaaS and multi-tenant assessments (Supabase / Firebase data-isolation testing) - Network and external perimeter penetration testing - Source code / secure code review How I work: authorized testing only, on systems you own or have permission to test. Everything is documented over Upwork so you get a written record of every finding, not a verbal hand-wave. I retest after you patch to confirm the holes are actually closed. Credentials: GXPN (GIAC Advanced Penetration Tester & Exploit Researcher), GCIH (GIAC Certified Incident Handler), SANS CTF winner, and an active national/international CTF competitor (web, reverse, crypto, forensics). I also handle WordPress malware removal and incident response. See my Project Catalog for a fixed-price option.

What does a HackerRank specialist do?

A HackerRank specialist configures technical assessments and integrity settings within the HackerRank for Work platform to support structured hiring workflows. This role focuses on building precise coding tests that accurately measure candidate skills while preventing cheating during remote evaluations. The specialist manages the entire lifecycle of an assessment, from defining role-specific questions to integrating results with applicant tracking systems.

  • Create and publish customized coding tests by selecting predefined roles or generating questions directly from job descriptions. Edit test sections to match specific technical requirements and preview the candidate experience before making the assessment live for applicants.
  • Configure test integrity modes and Proctor Mode settings to secure remote assessments against unauthorized assistance. Adjust company-level and test-level security options to balance candidate privacy with the need for verified, authentic coding submissions.
  • Set up and maintain integrations with applicant tracking systems, scheduling tools, and single sign-on providers. These connections allow recruiting teams to send test invites automatically and sync assessment outcomes directly into their existing hiring pipelines without manual data entry.
  • Generate summary reports and session-replay integrity data after candidates complete their assessments. Review these detailed logs to identify irregular patterns and support hiring managers in making informed decisions based on verified technical performance.

How to hire a HackerRank specialist on Upwork

Step 1: Post a job

Define the specific assessments and integrations you need to structure your technical hiring. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description. Describe your needs in a few sentences and Uma drafts a job post for the role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify which predefined roles or custom question sets the freelancer must configure within HackerRank for Work.
  • List the applicant tracking systems and scheduling tools that require integration with your assessment workflow.
  • Detail the required test integrity modes and proctoring settings for secure remote candidate evaluation.

Step 2: Evaluate candidates

Look for proof of configured ATS connections and published technical tests in their portfolio. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up this review.

  • Verify experience managing role definitions that generate accurate skills-based assessments for engineering teams.
  • Check for examples of summary and session-replay integrity reports used to support hiring decisions.
  • Confirm familiarity with HackerRank API tokens for enterprise-level system connections and data syncing.

Step 3: Interview your top choices

Discuss their approach to balancing candidate experience with strict test security protocols. Interviews can be scheduled and conducted within Upwork Messages with an immediate transcript and summary after each one.

  • Ask how they customize predefined roles to match unique technical requirements without breaking standard templates.
  • Review their process for troubleshooting failed integrations between HackerRank and external scheduling platforms.
  • Evaluate their method for enabling Proctor Mode while minimizing friction for legitimate test takers.

Step 4: Agree on scope and begin work

Set clear milestones for publishing tests and connecting your recruiting stack. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define deliverables such as published HackerRank tests aligned to specific job roles and verified skill sets.
  • Establish deadlines for configuring test integrity settings and validating ATS data synchronization flows.
  • Agree on the format for submitting assessment reports that highlight candidate performance and integrity flags.
