#01
Legacy system slowing delivery
Every change takes longer, releases are risky, and unsupported or tightly coupled components are holding the business back.
SERVICE
System Modernization & Stabilisation
Modernize aging systems incrementally — re-architecture, cloud migration and cost control, without a stop-the-world rewrite.
Let's talk about your systemWe'll reply within a few days with a concrete proposal.
What we deliver
What this looks like in practice.
When an existing system is hard to change, fragile, or expensive to run, you rarely need a big-bang rewrite. We re-architect, re-platform and migrate in safe increments — improving reliability, scalability and cost while the business keeps shipping.
Architecture documentation
Component-level design, data-flow diagrams, security model. A document the team actually uses.
Cloud platform choice
Azure, AWS, GCP, or hybrid — recommendation matched to tech stack, competence, and cost.
Infrastructure-as-code foundations
Terraform, Bicep, or CloudFormation modules. Infrastructure lives in code, version-controlled.
Security architecture
IAM, network design, encryption at rest/transit, compliance (GDPR, possibly ISO/SOC2).
Cost analysis & optimisation
Where the money goes, where reserved instances pay off, where auto-scaling saves. With concrete numbers.
Migration plan
If a cloud or platform switch is needed — phased plan, risks, and rollback strategy.
When you need this
This is where we come in.
#02
Migration without business interruption
A platform, cloud or major component must change, but customers and internal operations cannot stop during the transition.
#03
Fragile or expensive operations
Incidents, manual deployments and infrastructure costs are growing. You need staged stabilisation before the next growth phase.
A concrete example
What an engagement looks like in practice.
Anonymised, illustrative project example.
Starting point
A Hungarian startup signed a contract with a major European retailer and had to scale their AWS platform.
Week 1
Discovery
Workshop with the CTO, traffic projections (peak rate), compliance (GDPR + retail audit), cost constraints.
Weeks 2–3
Architecture
Multi-region AWS architecture, RDS read replicas, ElastiCache, CDN. Cost model and security review.
Week 4
Document & roadmap
30+ page architecture document, Terraform modules, phased migration plan from the existing setup.
Ongoing
Implementation guidance
Their team builds; we run weekly review checkpoints (ADRs, design reviews). Launch after a few months.
Outcome
The platform scaled substantially, costs stayed under control, and the deploy process became markedly faster.
Related services
Often these go together — adjacent services we also handle.
FAQ
Common questions
What do you need to know to design an architecture?
The discovery workshop (1 week) covers business goals, expected traffic and user volumes, security and compliance requirements, cost constraints, and your team's tech competence.
How do you decide which cloud platform is right?
Typically based on existing tech stack, team competence, cost, and specific service requirements (e.g., compliance, regions). Usually Azure, AWS, or GCP — we have senior experience in all three.
Do we use infrastructure-as-code from day one?
Yes — for any serious cloud setup IaC is the baseline. The discovery and architecture design already provide IaC-module breakdowns so implementation is faster and safer.
Who implements what you design?
Either your team — with our guidance (reviews, ADRs) — or we build the IaC foundations too. Both options work; depends on scope.
Get in touch
Let's understand the problem before we build the solution.
Tell us whether an existing business-critical system is holding you back or you are creating a new complex platform. In a 30-minute conversation we identify the right first engagement and whether we are a fit.
Best fit: multiple roles or tenants, critical integrations, sensitive data, complex business logic, long-term evolution, or direct business impact when the system is unavailable.
