Selected work

From complexity to clarity.

A few examples of how I turn operational challenges into practical improvements.

Via Mobility Operations & analytics

Making operational data useful.

A shared view of service performance that helps teams spot exceptions and decide where to act.

Clearer priorities. More consistent decisions.

  • SQL & Snowflake
  • Python
  • KPI reporting
Read the case study

The challenge

Operational information lived across separate sources, making recurring reporting and exception analysis harder to repeat consistently.

My contribution

Built reporting and monitoring tools using SQL, Snowflake, and Python. Connected operational signals, surfaced exceptions, and translated the analysis into reporting for field teams and partners.

The outcome

Created a reusable operating view for performance conversations and day-to-day decisions, giving teams a clearer basis for prioritisation.

Via Mobility Planning & process improvement

More useful service. The same resources.

Supply planning that brings demand, staffing, and operating constraints into one decision.

Extended service windows within the planned hours.

  • Scenario planning
  • Workforce forecasting
  • Stakeholder alignment
Read the case study

The challenge

Service demand, shift coverage, break requirements, and commercial targets needed to be balanced within an existing operating-hour envelope.

My contribution

Designed a supply replan that made the constraints and trade-offs explicit. Developed workforce forecasting tools to connect expected workload with future staffing needs.

The outcome

Extended weekday service windows while maintaining planned operating hours. Made capacity gaps more visible to support earlier staffing decisions.

everii Group Customer experience & leadership

A support team set up to succeed.

Clear support routines, useful customer signals, and regular coaching across a multi-product team.

Contributed to customer satisfaction above 92%.

  • Team development
  • Service operations
  • Customer automation
Read the case study

The challenge

Supporting multiple software products required consistent processes, visibility into service quality, and a team able to grow with customer needs.

My contribution

Introduced support structures and KPI routines, coached team members, and implemented customer monitoring automation. Planned webinars and product training for customers.

The outcome

Helped sustain customer satisfaction above 92%, with more structured team development and repeatable ways to monitor and improve support quality.

Built out of curiosity.

Independent prototypes exploring simpler ways to organise information.

Independent iOS prototype

Warranty Tracker

A purchase and receipt organiser that turns scattered documents into warranty timelines, return reminders, and claim records.

SwiftUI · Receipt OCR · Workflow design

About the prototype

The prototype brings receipt scanning, document storage, coverage tracking, and claim-packet exports into a native iOS workflow. It reflects the same approach I bring to operations: make the next action clear and keep the evidence close to the decision.

Independent research-tool prototype

RE:FACT

A research inbox for reviewing health and fitness claims in social videos, with evidence and editorial decisions in one place.

Research workflows · Prioritisation · AI integration

About the prototype

The prototype combines video discovery, claim prioritisation, source review, and reaction drafts. Its review flow distinguishes claims that need investigation from claims with supporting evidence, keeping human judgement central to the process.

Experience

Close to the work.

The next chapter

Back to Tokyo.
For the long term.

I’m moving back to Tokyo in December 2026 with my wife, who is Japanese, so she can be closer to her family.

I’m looking to bring my experience to an international company in Tokyo. Having lived and worked there, I bring first-hand experience of Japan alongside a career built across service, technology, and operations.

I’m interested in work where I can help teams perform, improve customer experiences, and turn complex information into practical decisions.
