PROCESS

A disciplined engineering process, from discovery to production

Every stage is managed with technical documentation, reviews and measurable outputs.

  1. 1

    Discovery & Planning

    We translate your business goals into technical requirements. Scope, risk and technology choices are clearly documented.

  2. 2

    System Architecture

    A scalable, secure and maintainable architecture is designed; data model, service boundaries and integrations are defined.

  3. 3

    Development

    Short iterations on a trunk-based flow; code review, type safety and static analysis are the default.

  4. 4

    Testing & QA

    Unit, integration and end-to-end tests run automatically before every deploy, alongside performance and security testing.

  5. 5

    Deployment (CI/CD)

    Zero-downtime, rollback-ready deployment pipelines with GitHub Actions + Docker + Kubernetes.

  6. 6

    Monitoring & Scaling

    Post-launch SLO tracking, alerting, logs/metrics/traces and capacity planning.

CASE STUDIES

Measurable results for our clients

We treat every project like a product — from initial goals to production metrics.

SAAS • B2B

AI-assisted CRM for a sales team

PROBLEM
Manual lead scoring slowed the team down and opportunities slipped through.
APPROACH
We added a RAG-based AI layer to a custom CRM: automatic scoring and next-best-action suggestions.
RESULT
Lead conversion up by a third; first-response time cut by more than half.

CMS • MEDIA

Multi-brand headless CMS platform

PROBLEM
Five brands ran on five separate WordPress installs; publishing took days.
APPROACH
One headless CMS with a locale/brand schema and a multi-channel delivery API.
RESULT
Publishing time reduced by two-thirds; infrastructure costs cut almost in half.

DEVOPS • FINANCE

Zero-downtime deployment & observability

PROBLEM
Monolithic services, weekly maintenance windows and no visibility into production.
APPROACH
Microservice extraction, blue/green deployments on Kubernetes, end-to-end tracing with OpenTelemetry.
RESULT
From one deploy a week to many per day; mean time to recovery down from hours to minutes.

FAQ

Frequently asked questions

Straight answers to what UK and European businesses ask us most.

Karga Consultancy is a London-based custom software development agency. We design and build bespoke software for growing businesses — e-commerce platforms, systems integration, AI automation, SaaS products, CRM and ERP systems, data platforms and cloud infrastructure — and support them in production across the UK and Europe.

We are registered in England and Wales (Company No. 15311819) with a registered office at 71–75 Shelton Street, Covent Garden, London, WC2H 9JQ. We work with clients across the United Kingdom and Europe, both remotely and on site.

Every project is scoped individually. After a free discovery call we document the scope, risks and technology choices, then send a detailed fixed-scope or time-and-materials proposal within a few working days. Most engagements start with a focused first phase so you see working software early.

Our core stack includes TypeScript, PHP, Python and Go; frameworks such as Next.js, Laravel, NestJS and FastAPI; React and Tailwind on the front end; PostgreSQL, MySQL, MongoDB and Redis for data; and AWS, GCP, Docker, Kubernetes and Terraform for infrastructure. We choose the right tool per project rather than forcing a single stack.

Yes. We build integrations across WooCommerce, Magento and headless storefronts; marketplaces like Amazon, eBay and Etsy; accounting systems such as Xero, QuickBooks and Sage; and payment and shipping providers including Stripe, Klarna, GoCardless, Royal Mail, DPD and DHL.

Yes. We treat every project like a product. After launch we offer SLO tracking, monitoring, security updates and continued development through CI/CD pipelines, so your system stays reliable and keeps evolving.
