Rungway: Scaling a Social Mentoring Platform
Challenge
A London-based HR-tech startup needed fractional CTO support to scale their social mentoring platform. The system could only handle 5 concurrent users before experiencing severe performance degradation — completely inadequate for their UK enterprise client base.
Solution
We delivered a complete architectural transformation as their interim startup CTO, migrating from Neo4J to a hybrid MySQL/NoSQL architecture for the primary data store (retaining Neo4J for AI/ML). Our team implemented microservices with domain-driven design, established Infrastructure as Code with AWS, built CI/CD pipelines, introduced event-driven architecture with SQS, and containerized the entire stack.
Results
- Scaled from 5 to 1000+ concurrent users
- Zero-downtime database migration
- Modern DevOps foundations established
- Event-driven microservices architecture
Opayo by Elavon: Payment Platform Transformation
Challenge
Leading UK fintech payment provider needed Kubernetes consulting to modernize their infrastructure and integrate new payment channels (Apple Pay, Google Pay) while maintaining 100% uptime for critical transaction processing across Europe.
Solution
We orchestrated a comprehensive AWS EKS migration with Kubernetes and Helm, implementing GitOps workflows and Infrastructure as Code using Terraform. Our team managed the transition from monolithic architecture to microservices, established Jenkins CI/CD pipelines migrated to Kubernetes, and scaled engineering culture across distributed teams.
Results
- Accelerated releases from every 2 weeks to multiple times per day
- Contributed to 10% revenue increase through faster feature delivery
- Reduced CI pipeline failures through automated testing
- Successfully integrated Apple Pay and Google Pay
AstraZeneca: Drug Delivery Tracking System MVP
Challenge
AstraZeneca needed to replace manual spreadsheet-based drug delivery tracking with a modern web-based tool to improve efficiency and accelerate time-to-market for pharmaceutical products. The system required integration with existing workflows while maintaining regulatory compliance.
Solution
We built a production-grade web application with REST APIs and automated CI/CD pipelines. Our team collaborated closely with stakeholders and business analysts to define requirements and align delivery with business goals. We architected scalable deployments on Kubernetes using Docker and Jenkins (config-as-code), establishing robust testing practices with JUnit and Spock.
Results
- Accelerated delivery by 40% compared to manual processes
- Cut deployment errors by 30% through automated pipelines
- Improved stakeholder confidence through transparent roadmap planning
- Delivered production-ready MVP on Kubernetes infrastructure

Exceptional Opportunities
Beyond Advisory: Co-founder Partnerships
Most of our work is fractional — time-bound, cash-based, designed to make you self-sufficient. But occasionally, we meet a founder building something we can't stop thinking about.
For the right opportunity
- Technical co-founder roles
- Equity-based partnerships
- Long-term commitment (2-5+ years)
- Full technical leadership & ownership
What makes it "right"
- 1Strong founder-market fit
- 2Problem I'm genuinely passionate about
- 3Clear path to meaningful scale
- 4Values and vision alignment
Note: I take on at most one co-founder role per year. Most conversations start as advisory engagements — it's the best way to test working chemistry.

Common Questions
Everything you need to know about working with us
1How quickly can we start?
Most engagements start within 1-2 weeks after our initial discovery call. For urgent projects, we can mobilize faster.
2What does a typical engagement look like?
Fractional CTO/CFO engagements typically run 3-6 months at 2-3 days per week. MVP builds are fixed-scope at 8-12 weeks. We tailor every engagement to your stage and needs — no cookie-cutter packages.
3Do you handle both technical and financial leadership?
Yes. Many startups need both CTO and CFO guidance but can't justify two executive hires. We offer integrated leadership covering technology architecture, financial planning, and investor relations.
4Do you work with non-technical founders?
Absolutely. Many of our clients are first-time founders without technical or financial backgrounds. We excel at translating complex concepts into clear business terms.
5What's your pricing model?
We work on retainer for fractional leadership (monthly commitment) and fixed-fee for defined projects like MVP builds or financial modeling. Investment varies based on scope and intensity — typically 60-80% less than equivalent full-time hires.
6Can you help with fundraising?
Yes. We prepare financial models, data rooms, and due diligence materials. We've supported raises from pre-seed through Series A across fintech, healthtech, and B2B SaaS.
7What's the difference between FP&A and accounting?
Accountants handle compliance and historical reporting. FP&A is forward-looking: financial modeling, forecasting, unit economics, pricing strategy, and investor communications. We provide strategic finance leadership, not bookkeeping.
8What's your tech stack expertise?
We specialize in cloud-native architectures (AWS, GCP), Kubernetes, Terraform, Python, Java, Postgres/Mysql, Gitops, and modern data/ML stacks. But our real value is in architectural thinking — we choose the right tools for your specific needs.
9Do you offer ongoing support after delivery?
Yes. We offer retainer arrangements for post-launch support, scaling assistance, and continued technical and financial leadership. Many clients transition from intensive builds to lighter advisory after launch.
10What makes you different from a dev shop?
Dev shops execute your specifications. We provide strategic leadership first — helping you figure out what to build, how to fund it, and how to set up your team for long-term success.
