About me & hiring

Hi, I’m Ry.

I’m an engineering leader with 20+ years of experience across SaaS, infrastructure, and compliance, most recently leading platform and security at Beatrust.

I specialise in untangling infrastructure challenges, scaling teams, designing pragmatic technical solutions, and making security and compliance a lot less painful. I can take a product or idea from zero to prototype to production—and help build the right team to support it.

I’m especially interested in companies solving real-world problems, and early-to-mid-stage startups looking to get to their next stage of growth.

A few achievements I am proud of:

• Led PCI-DSS Level 1 Service-Provider certification end-to-end—designed compliant architecture, managed the external audit, and achieved first-pass certification on schedule.
• Optimized cloud spend with usage dashboards and right-sizing policies, cutting monthly costs 9 % and eliminating idle instances across all teams.
• Drove security & compliance due-diligence for Privacy Mark and Tokyo Stock Exchange listing, clearing audit hurdles and enabling a successful IPO.
• Delivered cross-functional projects with distributed teams across multiple time-zones, cultures, and job functions, shipping key features and infra upgrades on time. 
• Hired to scale the team from 3 to 45 engineers while helping to establish clear structures for support, growth, and promotion. Including succession planning.
• Prototyped AI features using cutting-edge LLM-RAG pipelines and fine-tuned BERT models, and shipped a sentiment-analysis product.

Remote-first preferred; available to work from Japan or the UK. I am currently living in the JST (UTC+9) time zone. My current notice period is one month.

Depending on the role and responsibilities, I typically target compensation in the range of:

• 14,500,000 - 18,500,000 JPY per year
• 81,000 - 95,000 GBP per year
• 120,000 - 140,000 USD per year

I’m flexible and happy to adjust based on the scope, impact, and nature of the role.
