Enterprise Software Development

SOFTWAREFOR THE WAYLARGE TEAMSWORK

We engineer business-critical systems for large organizations, designed for your security review, integrated with your identity provider and systems of record, and documented so your own IT team can operate them.

01Our Approach

We design for the audit, the outage and the reorganization from the start, because enterprise software has to survive all three.

02Overview

Engineering for scale, governance and long service life

  • 01Systems of record
  • 02Process automation platforms
  • 03Legacy modernization

Enterprise software serves many departments, sits between systems such as SAP, Oracle and Salesforce, and answers to security, legal and architecture boards. This service covers that kind of build, including domain modeling, service design, integration through APIs and event streams, single sign-on, audit logging, observability and infrastructure as code. We document every decision so the system can be governed and maintained after we leave.

It applies when failure has a real business cost, when several teams and regions share one system, or when a platform your company relies on has reached the end of its supported life. We work inside your governance, with your architects and security officers, deliver in increments that each go through your change process, and prove behavior under load and failure before release.

03What We Do

Capabilities, End to End

01
Domain and service design

We model the business domain with your subject experts and draw service boundaries along it, choosing a modular monolith or microservices according to team structure and scaling needs.

02
Enterprise integration

Connections to ERP, CRM, HR and finance systems use documented APIs, Apache Kafka event streams or managed file transfer, with retries, dead-letter queues and monitoring on every interface.

03
Identity and access

Single sign-on through SAML or OpenID Connect, SCIM provisioning from your directory, fine-grained authorization and immutable audit logs align the system with your access policies.

04
Legacy modernization

We place a facade in front of the old system and move capabilities behind it one by one, so aging platforms retire gradually instead of in one cutover.

05
Resilience engineering

Redundancy across availability zones, automated failover, backups with tested restores and defined recovery objectives are designed in, then exercised through failure drills before go-live.

06
Observability and operations

Structured logs, metrics, distributed traces and alerting through OpenTelemetry and Datadog give your operations team the evidence to find a fault across services quickly.

06How It Runs

From Kickoff to Launch

01
Assessment
02
Target architecture
03
Incremental delivery
04
Transition to operations
01
Assessment

We review the current systems, interfaces, data flows, constraints and policies with your architects and security team, and agree on quality targets for availability, performance and recovery in writing.

02
Target architecture

The domain model, service boundaries, integration patterns and infrastructure are designed and reviewed with your architecture board, including a threat model and a migration path from the present state.

03
Incremental delivery

Capabilities are delivered in increments that pass automated tests, security scans and your change approval, each released to a limited group of users before it is opened to the organization.

04
Transition to operations

We run load, failover and recovery tests, complete the runbooks, train your support and operations staff, and stay on call with them through an agreed-upon stabilization period.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
A core system has to serve the whole organization

Several departments depend on the same data, the current platform is aging or fragmented, and any replacement must satisfy security, audit and procurement before it goes live. You need engineers who can work within that governance and still deliver working software at a steady pace.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Book a call

We design systems to support your SOC 2, HIPAA, PCI DSS or GDPR obligations, and we do not issue attestations ourselves. In practice that means mapping each relevant control to something concrete in the system, such as encryption, least-privilege access, audit logging, retention rules and change records, and keeping that mapping documented. Your security team is involved from the first workshop, and we supply the evidence your assessors request during their review.

In stages, starting with a pilot group that represents real usage. Feature flags and per-department configuration let us enable the system for one unit at a time while others stay on the existing process. Each stage has entry criteria, training for the staff involved, a support channel and a rollback path. Data is migrated per unit and reconciled, and lessons from each stage adjust the plan for the next.

It depends on how many teams will work on the system and how differently its parts need to scale. A modular monolith with strict internal boundaries is simpler to deploy, test and reason about, and suits most new builds. Microservices earn their operational cost when independent teams must release separately or one workload dominates. Our default is to start modular and extract services only where evidence supports it.

We start by agreeing targets with you, how much downtime and data loss the business can tolerate for each function, since those numbers drive cost. The architecture then follows, with redundant instances across zones, replicated databases, automated failover, and backups stored separately. Infrastructure is defined in Terraform so an environment can be rebuilt. Before launch we rehearse a failover and a restore instead of assuming they work.

We expect them and plan for them. An NDA is available on request before any detail is shared, and we complete vendor security questionnaires during onboarding. Delivery is organized into increments sized for your change advisory board, each with release notes, test evidence and a rollback plan. We use your ticketing, documentation and approval tools where you prefer, so the project leaves a record in your own systems.
