NA / 03 — Services

Fourteen practices,
one engineering discipline.

Each service listed below is delivered by the same senior team, against the same working principles. Engagements are scoped to fit the client's technical maturity and internal capacity, not to fit a pre-drawn package.

Index of services

S.01

Custom software development

What it includes
End-to-end delivery of business systems: domain modeling, backend services, data layer, and user interfaces built for a specific operational context.
Business problems it addresses
Off-the-shelf software that does not fit the process, and internal tools that have outgrown their original design.
Delivery approach
Discovery, architecture, iterative implementation with automated verification, deployment into a monitored environment, and ongoing evolution.
Expected operational benefits
Software that fits the actual workflow, remains changeable, and can be operated by the client's team.

S.02

Web application development

What it includes
Interactive applications for internal operations, customers, or partners — with typed contracts between backend and frontend, and considered accessibility.
Business problems it addresses
Legacy web portals with fragile state, slow interfaces, or interfaces that do not survive an accessibility review.
Delivery approach
Component-driven interfaces, server-rendered where it helps, progressive enhancement, and a shared design system.
Expected operational benefits
Interfaces that load quickly, remain usable across devices, and are practical to maintain.

S.03

Business system development

What it includes
Line-of-business platforms: ERP-adjacent tools, operations dashboards, planning and reporting systems.
Business problems it addresses
Business logic scattered across spreadsheets, email threads, and ad-hoc scripts, with no single source of truth.
Delivery approach
Explicit domain modeling, workflow-first design, integration with existing systems, and role-based access.
Expected operational benefits
A defensible operational backbone, with auditable data and predictable behavior.

S.04

Cloud architecture

What it includes
Reference architectures on major cloud providers, tuned for the workload profile, cost model, and regulatory context.
Business problems it addresses
Environments assembled reactively, without a coherent view of cost, resilience, or ownership.
Delivery approach
Assessment, target architecture, staged implementation with infrastructure-as-code, and documented failure modes.
Expected operational benefits
A cloud footprint that is intentional, measurable, and appropriate for the traffic and data at hand.

S.05

Cloud migration

What it includes
Migration of existing systems to cloud infrastructure — lift-and-shift where appropriate, refactoring where it earns its keep.
Business problems it addresses
Aging on-premise systems, expiring hardware, or fragmented environments that need consolidation.
Delivery approach
Inventory, dependency mapping, migration waves with reversible steps, and post-migration validation.
Expected operational benefits
Predictable execution, controlled downtime, and a clearer operating environment on the other side.

S.06

API development and integration

What it includes
Public and internal APIs with clear contracts, versioning, and authentication — plus integration with third-party systems.
Business problems it addresses
Point-to-point integrations that break on every change and undocumented endpoints that only one person understands.
Delivery approach
Contract-first API design, generated client libraries, comprehensive testing, and observable request flows.
Expected operational benefits
Integrations that can be extended, replaced, and reviewed without archaeological work.

S.07

IT infrastructure consulting

What it includes
Independent review and design of network, compute, storage, and identity infrastructure.
Business problems it addresses
Growth-driven infrastructure whose original assumptions no longer hold.
Delivery approach
Assessment against defined criteria, prioritized recommendations, and support during implementation.
Expected operational benefits
A written baseline of the current environment and a clear path to a target state.

S.08

Cybersecurity consulting

What it includes
Threat modeling, application security review, identity and access hardening, and preparation for security audits.
Business problems it addresses
Security posture assumed rather than verified, and controls that exist on paper but not in code.
Delivery approach
Concrete threat model, gap analysis against a defined standard, remediation plan, and evidence collection.
Expected operational benefits
A security program the client can describe accurately to auditors, customers, and their own board.

S.09

Data management solutions

What it includes
Data storage, movement, transformation, and access patterns for operational and analytical use.
Business problems it addresses
Reports built on exports, duplicated records, and decisions made against data no one fully trusts.
Delivery approach
Data modeling, pipeline design, retention policy, and access controls — with lineage that can be inspected.
Expected operational benefits
A coherent data layer that supports operations and reporting without side-channel spreadsheets.

S.10

DevOps and deployment automation

What it includes
Continuous integration and delivery pipelines, environment provisioning, observability, and release management.
Business problems it addresses
Slow, error-prone deployments and long feedback loops between writing code and seeing it run.
Delivery approach
Pipeline design, infrastructure-as-code, environment parity, and monitored rollouts.
Expected operational benefits
Deployments that are boring — predictable, reversible, and safe to run frequently.

S.11

Software modernization

What it includes
Refactoring, replatforming, and staged replacement of legacy systems.
Business problems it addresses
Software that still works but is expensive to change, hard to hire for, or blocking the next set of business decisions.
Delivery approach
Strangler-pattern migration, characterization tests, incremental extraction, and safety nets around the legacy core.
Expected operational benefits
Systems that continue to run through the modernization, with reduced risk at each step.

S.12

Technical audits

What it includes
Independent review of code, architecture, cloud environment, or operational posture.
Business problems it addresses
Uncertainty about whether an existing system is well-built, secure, or worth continuing.
Delivery approach
Structured review against defined criteria, with findings ranked by impact and effort.
Expected operational benefits
A written, actionable assessment that the client can use to make investment decisions.

S.13

Quality assurance and software testing

What it includes
Test strategy, automated test suites, performance testing, and release verification.
Business problems it addresses
Regressions that only surface in production and testing that depends on manual heroics.
Delivery approach
Test pyramid design, framework selection, automation of the highest-value tests, and integration into the delivery pipeline.
Expected operational benefits
Confidence to release more frequently, with fewer surprises.

S.14

Ongoing technical support

What it includes
Long-term operation, monitoring, incident response, and continuous improvement of systems we build or take over.
Business problems it addresses
Handovers that end in silence, and systems that slowly degrade because no one owns them.
Delivery approach
Defined support model, on-call arrangements, monthly review of health metrics, and a written change log.
Expected operational benefits
Systems that remain healthy, current, and understandable as the years pass.

Note on scope

We do not publish fixed prices, guaranteed timelines, or guaranteed business outcomes. Every proposal is written after we understand the specific system, team, and constraints involved.

Engagement models

How we structure work.

Network of nodes forming a cloud diagram on a deep navy background
  • End-to-end delivery. We take responsibility for the full system: design, build, ship, operate.
  • Team augmentation. Senior engineers embedded into an existing team, with shared standards and shared reviews.
  • Advisory & review. Independent technical judgment on architecture, security, or a specific decision.
  • Long-term operation. Managed running of systems we build, including monitoring, incident response, and continuous improvement.
