AI workflows
LLM-based workflows for products, operations, and teams.
Platform teams
Built and led platform / infrastructure teams while technically contributing across Oxylabs, Barclays, Danske Bank, and Genius Sports.
01
What I do
I help decide what should exist, build or improve it, and make sure the platform, delivery, reliability, security, and ownership are not afterthoughts.
Fractional CTO / senior technical leadership
I have worked across two-person startups and 140,000-person enterprises: product, engineering, people leadership, and operating models.
Outcome: business-first technical direction, planning, decisions, engineering practices, observability, team processes, and help leading implementation as the system grows.
DevOps, infrastructure, and platform implementation
Hands-on help with Linux/Unix, networking, containers, Kubernetes, CI/CD, public and private cloud, observability, reliability, and security.
Outcome: practical infrastructure plan, implementation support, deployment setup, monitoring, and clear ownership.
Technical, code, system, and AI reviews
Before scaling, funding, enterprise clients, vendor work, or AI-generated code gets serious, I check whether the system can be owned, secured, kept available, and changed safely.
Outcome: clear risks and findings, mitigation options, practical changes, and AI workflow/prototype guidance where it helps.
Websites, CRMs, portals, and internal tools
From idea to first version: clarify users, flows, constraints, security, reliability, and handover before turning it into a system.
Outcome: a scoped website, CRM, portal, dashboard, tracker, or reporting workflow that can start small and grow with the business.

Technical reviews before expensive mistakes
I review code, architecture, infrastructure, deployment, and operating practices to find real risks, mitigation steps, and the changes worth doing first.
Reviews
- code quality and maintainability
- security, access control, and dependencies
- architecture, infrastructure, and cloud setup
- CI/CD and deployment reliability
- monitoring, alerting, and incident readiness
- scaling, high availability, and performance
- AI-assisted code or workflow risk
Typical output
- key risks and findings ordered by impact, with mitigation options
- short written report
- recommended next steps
- technical leadership and/or hands-on help implementing the changes
03
How I think about the work
I focus on business value. Before choosing technology, I want to understand who we are building for, what the user journeys look like, what result we want, and how quickly we need to get there.
The technical solution can be simple or complex. The important part is that the complexity matches the business goal, the risks, the constraints, and the stage of the company.
I have broad experience and try to stay open and direct. Depending on what is needed, I can advise, review the direction, or work alongside the team to help solve the problem.
