Architecture & design
System design, data models, API contracts and infrastructure that will still make sense in five years.
Development
Secure web and mobile applications, built by the team that audits them.
From individual developers to full scrum teams, we provide professional and experienced engineers specialised in the rapid development of secure web and mobile applications. We follow industry best practices, with security, testing and performance baked in from the start — not hastily retrofitted afterwards.

Development services
Development & testing
Weekly sprints, code review on every change, high unit-test coverage and continuous integration and deployment.
UX, UI & SEO
Interfaces people can use without a manual, built accessible and fast from the first commit.
Infrastructure & operations
Docker, AWS, serverless and CI/CD pipelines — set up, monitored and optimised for cost.

Best practices we build to
The same rules our auditors hold other teams to. They are not a checklist we add at the end; they are how every project is set up on day one.
- 01Security by design
Threat modelling before the first sprint, OWASP ASVS as the baseline, least-privilege access and secrets kept out of code and out of chat.
- 02Tests you can trust
High unit-test coverage, integration tests on the critical paths and automated checks in CI so a green build actually means something.
- 03Code review on every change
Nothing reaches the main branch unreviewed. Reviews check behaviour, security and readability — not just style.
- 04Weekly sprints, working software
Short cycles with a demo at the end of each. You see progress every week and can change direction without a renegotiation.
- 05Continuous integration & deployment
Every merge is built, tested and deployable. Releases are routine, small and reversible instead of quarterly events.
- 06Infrastructure as code
Environments are defined in Terraform or CDK, reproducible and reviewable — no hand-configured servers anyone is afraid to touch.
- 07Observability from day one
Structured logs, metrics, alerts and cost monitoring ship with the first release, so problems are graphs before they are complaints.
- 08Dependency & vendor hygiene
Actively maintained open-source libraries, automated vulnerability scanning and a vendor examination before any new service touches production.
- 09Documentation that survives handover
Architecture decisions, runbooks and onboarding notes written as we go — so your team, or the next one, can run it without us.

Blockchain solutions
Everlution provides blockchain solutions for start-ups and established businesses in the information and financial sectors. We mix our product development, UX and technical experience with financial and business knowledge to create practical solutions using blockchain’s unique features — and, because our security team audits crypto and fintech platforms for a living, we design them to stand up to regulation (MiCA, DORA) and to attackers from day one.
- Architecture and development of blockchain-based products and integrations
- Smart-contract and wallet security review, key management, incident response
- MiCA / DORA readiness for crypto-asset and fintech services
- Advisory for boards and founders: where blockchain adds value, and where it does not

Technologies
We are open-source advocates and use actively supported, well-tested tools, libraries and frameworks — ensuring future maintainability and the availability of developers. Our projects are primarily built on TypeScript with Node.js or PHP 8 with Symfony, with a general preference for Docker containerisation, React and serverless architectures where appropriate.
On AWS we build on Lambda, API Gateway and AppSync (GraphQL), Cognito for identity, SNS and SQS for messaging, and ElastiCache for speed. When a project is data-heavy — search, analytics, large unstructured sets — we add Elasticsearch, Redis, queues and document stores next to MySQL, and pick the right tool for each job rather than one database for everything.

Development
Our approach
- Continuous learningWe encourage the team to contribute to the development community through talks, open-sourced code, blogs and even books. Regular sessions at Everlution University keep everyone current with the latest trends, threats and techniques.
- Code review & vendor examinationInternal training, code reviews and vendor examinations make sure everyone is constantly learning — and that nothing untested reaches production.
- Best value for moneyA blended day rate on a time-and-materials basis, with discounts for longer-term assignments and partnerships.
Careers
Further your career at Everlution
Whether you are a school leaver or an industry veteran, full-stack or specialist, engineer or business analyst, we are always looking for talented people to join and improve our company and projects. We work on large, interesting systems that must be secure and operate under high load — often built from scratch with innovative technologies. Many of our junior developers have gone on to great things at high-profile technology companies, or become CTOs and CIOs themselves.
