§ 03Track record
PCI-DSS and zero trust across cloud and edge for a large e-commerce platform
A large e-commerce SaaS platform handling card payments needed PCI-DSS compliance across a multi-cluster cloud estate and its edge layer. One of our experts reports leading the PCI-DSS programme and a zero-trust model spanning cloud and edge, as part of a head-of-infrastructure role. Outcome: compliance work carried as an infrastructure programme rather than a paperwork exercise.
Building an in-house cybersecurity team and cutting incidents
Security was handled ad hoc while traffic and attack surface kept growing. One of our experts reports building an in-house cybersecurity team and owning WAF and compliance work. Reported outcome: security incidents down by roughly 30%.
Seven-figure cloud budget, about a fifth cut
A high-traffic e-commerce platform ran multiple Kubernetes clusters on AWS with a seven-figure yearly cloud bill. One of our experts reports owning that budget, introducing Karpenter-based autoscaling and GitOps-managed capacity, and cutting costs by about 20% while raising peak scalability by around half, by their own figures.
Multi-cluster EKS operations for petabyte-scale monthly traffic
Global cloud operations for high-traffic e-commerce, moving petabytes of traffic a month across several EKS clusters. One of our experts led these operations with GitOps (ArgoCD), infrastructure-as-code (Terraform Cloud) and autoscaling, so changes were reviewable and repeatable rather than hand-applied.
Data lake and real-time analytics for an e-commerce platform
Analytics queries were slow and real-time signals were hard to get. One of our experts reports building out a data lake and real-time analytics layer with streaming and columnar storage. Reported outcome: data retrieval roughly 40% faster.
Restaurant and club booking e-commerce backend in under a year
A hospitality startup needed an e-commerce backend for restaurant and club bookings, plus marketing and mobile APIs. As CTO, one of our experts led a hybrid team of around twenty people, ran code reviews and outage investigations, and delivered the backend in under a year.
Modernizing a security and vehicle-tracking platform
A security and risk-tracking business ran legacy systems and dated mobile apps while adding in-vehicle monitoring. As Head of Engineering, one of our experts led a resilient platform rebuild on PHP Symfony and AWS, alongside legacy and mobile modernization.
Head of Engineering: code reviews, mentoring and serverless AWS
A startup with cross-functional web and mobile teams needed engineering structure. One of our experts, as Head of Engineering, set up code reviews and mentoring and ran an AWS stack mixing Lambda, Elasticsearch, EC2 and RDS, with native iOS and Android apps.
Multi-region enterprise infrastructure and post-merger IT integration
A multinational group with offices across several continents needed one coherent network and data architecture, and to absorb acquired businesses. For six years, one of our experts managed IT infrastructure: enterprise network architecture across regions, database administration, and IT integration after acquisitions.
CTO for an expert social network with three remote teams
An early-stage startup building a social network for experts had engineering split across three remote teams. As CTO, one of our experts coordinated the teams and the platform's architecture.
§ 04What you can book
Edge drift audit: when incidents come from drift plus automation
Many modern incidents aren't one bad deploy. They come from drift plus automation: fragmented caches, generic rate limits that block real users, WAF exceptions that pile up, auth storms and scraping.
Review the edge, WAF, rate-limit and cache config against real traffic, find where drift has crept in, and propose guardrails so automation stops amplifying it.
A ranked findings list with concrete config changes and a drift-prevention checklist.
PCI-DSS readiness review for a fintech or e-commerce startup
A startup is about to take card payments directly or faces its first PCI-DSS assessment.
Map where cardholder data flows, check network segmentation, secrets, access and logging, and look at the edge controls in front of payment endpoints.
A scoped gap list, a remediation plan in order, and the architecture changes that shrink PCI scope.
Kubernetes and AWS cost review
The cloud bill grows faster than traffic.
Review node pools, autoscaling (including Karpenter), idle and non-production environments, data transfer and storage, and how capacity changes are managed.
A prioritized savings plan with the risk of each change to peak capacity spelled out.
Infrastructure and security due diligence for an investor
An investor or acquirer wants to know whether a target's infrastructure can scale and whether its security posture is a liability.
Cloud architecture and cost, IaC and deployment hygiene, edge and WAF posture, compliance scope, incident history and on-call reality.
