I am Onesmo Stephen Gobrey

I help school leaders connect finance, curriculum, and stewardship—so decisions match what happens in the classroom.

FMVA-certified advisor for schools and finance · Also Scrum Master & Product Manager for product teams

I partner with school directors, finance leads, and teaching teams to align bookkeeping, reporting, and commerce instruction with how your institution runs day to day. Based in Tanzania (UTC+3), I also support remote product teams worldwide.

Joshua Schools Magugu, Tanzania · Schools · Finance & curriculum

Connecting financial practice with classroom reality

Role: Advisor on financial systems and curriculum alignment.

  • Moved stewardship reviews from monthly snapshots to a weekly cadence within one term.
  • Replaced ad hoc finance checkpoints with a defined four-role ownership matrix.
  • Connected commerce curriculum to how the school operates day to day.

Clearer budget decisions and stronger links between financial records and instructional goals within one term. Read the school director’s view.

RustyBytes · Nottech Ltd · Software product delivery

Aligning engineering and stakeholders on what ships next

Role: Scrum Master and Product Manager.

  • Kept one clear sprint goal visible and trade-offs explicit in the backlog.
  • Bridged stakeholder and engineering conversations before scope churn hit the sprint.
  • Supported incremental releases with sustainable pace.

Measurably fewer late scope changes over successive planning cycles; stakeholders gained a shared picture of what was in flight. See leader feedback.

Common questions

What does a Scrum Master do?

A Scrum Master facilitates agile delivery by removing impediments, coaching the team on Scrum practices, and ensuring the product backlog is healthy. I help cross-functional teams at organisations like RustyBytes and Nottech Ltd ship increments that match real user and business needs.

Can I hire you remotely?

Yes. I work with remote and distributed teams across time zones. My workflow is built around asynchronous communication, video stand-ups, and collaborative tools like Jira, Notion, and Slack. Get in touch to discuss your project.

What time zone are you in?

I'm based in Tanzania, East Africa Time (UTC+3). This overlaps comfortably with European business hours and allows same-day collaboration with teams across Africa, the Middle East, and Asia.

What certifications do you hold?

I hold the Professional Scrum Master I (PSM I) certification from Scrum.org, the Financial Modeling & Valuation Analyst (FMVA®) certification from Corporate Finance Institute, and a Master of Divinity from Global University. See my credentials for verification links.

How do I start working with you?

The easiest way is to book a free 30-minute discovery call or send me a message through the contact form. I'll respond within 24 hours to discuss scope, timeline, and next steps.

What tools do you use with teams?

I work day to day in Jira, Notion, and Slack, alongside Google Workspace, video calls, and spreadsheets. I adapt to the stack your organisation already uses.

How do you use AI in your work?

I may use AI for drafting and summarising my own notes, always with human review. I do not put confidential backlog items or client secrets into prompts. Priorities stay grounded in stakeholders, users, and team evidence.
