Custom Software Development
Long-lived web, API and back-office systems built with strong architecture, type safety and a deliberate test culture.

DocCheck Forest GmbH partners with ambitious teams to build platforms, modernize infrastructure and run secure operations — without the theatre of fashionable tooling.
Company overview
We are a multidisciplinary team of software engineers, cloud architects, security specialists and product designers. Our work is grounded in long-term thinking — software that other engineers are comfortable maintaining five years from now.
From greenfield platforms to legacy modernization, we operate as a single accountable partner across the lifecycle: discovery, architecture, delivery, security review, observability and ongoing care.
Core IT solutions
Most of our engagements blend two or three of these tracks. We shape teams around outcomes, not service lines.

Long-lived web, API and back-office systems built with strong architecture, type safety and a deliberate test culture.
Multi-region architectures on AWS, Azure and GCP with infrastructure-as-code as a first-class citizen.
Pipelines, warehouses and product-grade dashboards your operators actually use.
Threat modelling, SSDLC and continuous controls — designed into delivery rather than bolted on.
From ETL orchestrations to event-driven workflows linking the systems already running your business.
Technology expertise
We are deliberately polyglot. The technologies below are ones we ship to production regularly — not a long marketing list.
Industry focus
We are domain-curious by nature. Most of our recent engagements cluster in the sectors below, where regulation, scale and integration complexity reward careful engineering.
Trading, risk, payments and back-office platforms with strong audit and uptime expectations.
Clinical data products, patient portals and HIPAA/GDPR-aligned integration layers.
Operational dashboards, IoT ingestion, and warehouse and fleet automation systems.
Citizen services, internal portals and accessibility-first applications.
Embedded engineering capacity for scale-ups iterating on multi-tenant platforms.
Telemetry, billing systems and grid-edge integrations with rigorous SLAs.
Software development process
Clarify outcomes, constraints and the shape of the problem.
Architecture, interface and operational model agreed before code.
Iterative delivery with weekly demos and reviewable increments.
Security, performance and reliability rounds before production.
Observability, support and a tight feedback loop with users.

Cloud & infrastructure
We design infrastructure that operators can reason about at 3 a.m. Reproducible environments, declared topology, observable behaviour, and recovery paths exercised before incidents — not during them.
Cybersecurity
Threat modelling, secure SDLC, hardened defaults and continuous control validation. We help teams ship faster precisely because the security work is no longer a surprise at the end.

Why choose us
We are senior by default, deliberate about scope, and rare in our willingness to say no when a different approach will serve you better.
No layers between you and the people writing the code.
Architecture that ages well — measured in years, not sprints.
We tell you what's hard, what's risky, and what we'd avoid.
Selected work

A strangler-fig migration onto an event-driven core reduced dispatch latency by 73% and let the operations team retire three legacy services over eighteen months.
Sub-second risk views across 6M positions, designed for audit and engineered for the night the network behaves badly.
Replaced four siloed tools with a single accessibility-first interface and cut administrative time per appointment by a third.

We joined a four-person internal team and helped grow a multi-tenant platform through a 9× usage increase without rebuilding the foundations.
Team values
These aren't posters on a wall — they show up in how we review work and how we hire.
Where the two conflict, we'll usually pick craft and explain why.
We translate. Diagrams over jargon. Decisions written down.
The person closest to the work makes the call — and signs it.
Small, frequent upgrades to tooling, tests and docs every week.
Strong opinions, weakly held. We argue about ideas, not people.
We design for the engineer on-call, not just the user on screen.
