About Onesmo Gobrey
Scrum Master, Product Manager & Educator in Tanzania
I bring together technology delivery, financial stewardship, and theological depth. My path spans software products, secondary education, accounting, and Christian ministry, always with people at the centre.
For 13+ years I have mentored youth as a teacher with Compassion International Tanzania (TZ0600). Today I serve as Scrum Master and Product Manager at RustyBytes and Nottech Ltd, helping teams align around clear goals and ship meaningful work.

Selected work
Concrete examples of how I partner with teams and organisations—without claiming numbers that are not mine to publish.
Aligning engineering and stakeholders on what ships next
Role: Scrum Master and Product Manager on cross-functional delivery.
What I did
- Facilitated Scrum events and kept the team focused on a clear sprint goal.
- Refined and ordered the product backlog so priorities matched user and business needs.
- Bridged conversations between stakeholders and engineers to reduce last-minute scope churn.
- Supported incremental releases with transparent progress and sustainable pace.
Outcomes
Delivery stayed centred on agreed priorities; stakeholders gained a shared picture of what was in flight and what was next. See how leaders describe the collaboration.
Tools: Jira, Notion, Slack, video stand-ups, Google Workspace
Connecting financial practice with classroom and institutional reality
Role: Advisor on financial systems and curriculum alignment (theory to practice).
What I did
- Worked with leadership to relate bookkeeping and reporting to how the school actually operates day to day.
- Helped connect commerce and curriculum so students see ideas in real institutional context.
- Supported clearer stewardship conversations between administration and teaching teams.
Outcomes
Stronger link between financial records, instructional goals, and practical impact for the school community. Read the school leader’s perspective.
Tools: Spreadsheets, documentation, in-person and remote working sessions
Delivery in an AI-assisted world
I use AI tools carefully—for drafting, summarising my own notes, and speeding up research hygiene. Every output gets a human review. I do not put confidential backlog items, personal data, or client secrets into prompts as if they were disposable. Priorities and commitments still come from stakeholders, users, and evidence from the team—not from unchecked generated text.

- Start: Book a free 30-minute discovery call or use the contact form. I usually reply within 24 hours.
- Shapes of work: Ongoing Scrum Master or product support for a squad, a focused engagement around backlog and roadmap clarity, workshops or coaching blocks, and education or curriculum projects aligned with schools and non-profits.
- What I am not: I am not a full-time software engineer for hire; I lead alignment, process, and product decisions alongside your technical team.

Frequently Asked 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 (e.g. Zoom or Google Meet), and spreadsheets when we need shared clarity on priorities or finances. I adapt to the stack your organisation already uses. See tools I use with teams for a grouped list.
How do you use AI in your work?
I may use AI assistants for drafting, summarising notes, and research hygiene, and I always review outputs for accuracy. I do not treat confidential backlog details, personal data, or client secrets as disposable prompts. Product and prioritisation decisions stay grounded in stakeholder input, user needs, and team evidence—not unchecked generated text. Read more under Selected work.
