Jack Robinson.
Tech lead & solutions architect.
Enterprise-grade experience, hands-on in the code. I design the architecture, build the system, and lead the team — for product teams and large organisations in London and remote.
About
The person behind
the work.
I'm a London-based Tech Lead and Solutions Architect with enterprise-grade pedigree — I've spent the better part of a decade working with some of the world's largest organisations, designing and delivering systems at a scale most engineers don't encounter. That background informs every engagement I take on, regardless of size.
I move fluidly between architecture, engineering, and leadership. I'll design the system, write the code, and lead the team — sometimes all three on the same contract. Five years of hands-on software engineering means I don't just draw boxes on diagrams; I know what it takes to build what I design.
I work on a contract basis. No padding, no unnecessary process — just focused engagement on the problems that matter. If you need someone with serious enterprise experience who can operate at any level of the stack, we should talk.
Services
What I bring to the table.
Focused engagements with meaningful outcomes. Whether you need help building, scaling, or making sense of what you already have.
Cloud Architecture
AWS-native designs that scale. Serverless, container-based, or hybrid — built with cost, reliability, and maintainability as first-class concerns.
- —Solutions architecture & design
- —AWS Well-Architected reviews
- —Infrastructure as Code (Terraform)
- —Cloud cost optimisation
Full-Stack Engineering
End-to-end product development with TypeScript across the entire stack. From API design to polished frontend — shipped, tested, and documented.
- —React / Next.js frontend
- —Node.js / Python backend
- —API design (REST & GraphQL)
- —CI/CD pipeline setup
Technical Leadership
Fractional CTO or hands-on tech lead for engineering teams. Drive standards, unblock delivery, and build the culture that retains engineers.
- —Engineering process improvement
- —Code review & mentoring
- —Hiring & team structure
- —Stakeholder communication
Architecture Review
An independent, objective review of your existing systems. Clear findings, prioritised recommendations, and an honest assessment of risk.
- —System design audit
- —Performance & scalability analysis
- —Security posture review
- —Written recommendations report
Work
Selected engagements.
Clients are kept confidential. These are representative examples of the kind of work I take on.
Automotive — AWS Serverless Migration
Inherited a heavily over-provisioned AWS estate built on always-on ECS and RDS instances with years of accumulated infrastructure debt. Designed and executed a full migration to a serverless-first architecture: Lambda, API Gateway, DynamoDB, S3, and EventBridge — with infrastructure fully codified in AWS SAM. Eliminated redundant services, consolidated pipelines, and restructured the deployment model around isolated, independently deployable units.
95% reduction in monthly AWS bill. 80% faster time-to-live per deployment. 99% of legacy technical debt eliminated.
Personal Product — Exercise Challenge App
↗ Live siteDesigned and built exercisechallengeapp.com end-to-end as a solo founder — from product concept through to live production. A full-stack team fitness challenge platform featuring 150+ exercise types, real-time leaderboards, a 5-tier weekly league system with promotions and relegations, instant points calculation, achievement badges, and personal goal tracking. Architected for scale from day one, with live updates, a clean consumer-grade UI, and a zero-friction onboarding flow.
500+ teams active on the platform. Fully self-funded and profitable. Built, shipped, and operated entirely by one engineer.
Automotive — GCP Infrastructure & AEM Decoupling
A major automotive client had multiple web applications tightly coupled to Adobe Experience Manager, meaning every deployment — no matter how small — required a full AEM release cycle. Designed a new GCP-native infrastructure to host their apps independently, extracted the applications from AEM as standalone codebases, and architected a deployment pipeline that allowed each app to ship on its own cadence. AEM was retained where it added value (content authoring) but removed entirely from the critical path of code deployments.
Teams able to deploy web apps independently of AEM for the first time. Release cycle reduced from weeks to hours. Clear separation of content management and application concerns.
