01About

Pay it forward.

“I’m an innovator, creative thinker and problem-solver with a passion for helping, enabling and developing other people. It’s why I travel the world as a public speaker and trainer, and why I have deep roots in open source: I love giving back to people and to the ecosystem of technology. ‘Pay it forward’ is the phrase I stick by.”

02ByteHire

Technical talent. Precisely hired.

Paul’s company. ByteHire is the technical validation layer between the candidate market and your interview process: engineers assessing engineers, so only evidence-supported candidates reach your calendar.

ByteHire

Founded by leaders from the open source community

01 Candidate claims

High volume. Unverified.

02 The Technical Validation Layer

Role context, practitioner judgement, evidence. Where the noise stops.

03 Focused shortlist

Few. Precise. Examined.

Right first shortlist
80%

of roles filled from the first shortlist, because every candidate arrives with evidence attached.

Interviews that convert
90%+

interview-to-offer conversion. Senior time goes to depth, judgement and fit.

Less wasted screening
60–90%

reduction in internal screening workload for hiring teams.

Validation sequence01 / 06

  1. 01

    Calibrate the role

    Technical domain, delivery environment, seniority and the evidence a credible candidate should show.

  2. 02

    Set evaluation criteria

    Subject matter experts define depth, architecture, production maturity and leadership judgement.

  3. 03

    Examine candidate claims

    Real contribution and practical judgement, separating exposure from genuine capability.

  4. 04

    Capture the evidence

    A proprietary platform structures criteria, practitioner notes, concerns and recommendations.

  5. 05

    Produce the Screening Pack

    Claim, observed evidence, strengths, gaps, role alignment and interview focus, in one readable pack.

  6. 06

    Hand over a shortlist

    Interview time goes to the strongest candidates. The final decision stays with the client.

  • Technical co-founders
  • Delivery leads
