Company
An engineering company,
not an agency.
Intercon Software is the engineering division of Intercon Group. We exist to build the software that enterprises depend on to operate, compete, and grow — systems measured in decades, not sprints.
Mission
To engineer software that connects people, systems, and organizations — with the rigor, reliability, and long-term thinking that mission-critical operations demand.
Vision
A world where every enterprise operates on software engineered with the same precision as the physical infrastructure it depends on — resilient, observable, and built to last.
Engineering principles
Architecture before code
We model systems before we write them. Decisions made on whiteboards cost less than decisions made in production.
Quality before speed
Velocity is a consequence of discipline. We ship fast because we engineer carefully.
Scalable by default
Every system we build is designed to handle ten times its launch load without rewrites.
Security by design
Threat modeling is part of architecture, not an audit after launch.
Our trajectory
2019

Engineering philosophy
We engineer the way
infrastructure is built.
Software that runs hospitals, banks, and logistics networks cannot be built like a marketing site. Our principles are borrowed from civil engineering: model first, build to spec, and design for the loads no one has seen yet.
Architecture before code
We model domains, data flows, and failure modes before a single line is written. The cheapest bug is the one never created.
Security by design
Threat modeling, least privilege, and secure defaults are architectural decisions — not compliance checkboxes.
Long-term maintainability
We write code our successors can read. Systems should outlive the people who built them.
Scalable systems
Every service is designed to handle ten times its launch load without rewrites or re-architecture.
Business impact
Engineering decisions are business decisions. We measure success in outcomes, not output.
Quality before speed
Velocity is a consequence of discipline. We ship fast because we engineer carefully.
Services
Sixteen disciplines.
One engineering standard.
Every service is delivered by senior engineers, governed by the same architecture review, and held to the same production bar. Choose one or compose them into a platform.
Enterprise Software
Large-scale systems engineered for reliability, observability, and decades of operation — the software your business cannot run without.
Business value
Reduce operational risk and unlock new revenue models.
Technologies

Technologies
A stack chosen
for the long term.
We are not tied to a vendor. We choose technologies the way structural engineers choose materials — for the loads they must bear and the decades they must last.

Industries
Domain depth,
not generic software.
We engineer for the constraints of your industry — the regulations, the failure modes, and the economics. Software that fits your world, not the other way around.
Healthcare
Challenge
HIPAA compliance, interoperability, and patient data security across fragmented systems.
Solution
HIPAA-ready platforms, FHIR APIs, and EHR integration with audit-grade logging.
Business benefit
Compliant systems that clinicians actually want to use.
Why Intercon
The difference is
in the defaults.
Most agencies optimize for billable hours. We optimize for the system still running in 2035. The contrast is not subtle.

Development process
Nine steps.
Zero surprises.
A process built for enterprises that need predictability. You always know what is being built, why, and what comes next.
01
Discovery
We learn your business, constraints, and the outcome that defines success.
02
Business Analysis
We translate goals into requirements, user journeys, and measurable acceptance criteria.
03
Architecture
We model the system — domains, data, failure modes — and document decisions in ADRs.
04
UI/UX Design
We design the interface as a system, accessible and consistent across every surface.
05
Development
Senior engineers build in vertical slices, shipping working software every week.
06
Testing
Automated suites run on every commit. Quality is a gate, not a phase.
07
Deployment
We ship with progressive rollouts, observability, and instant rollback.
08
Support
We stay. SLOs, on-call, and a team that already knows your system.
09
Continuous Improvement
We measure, refine, and evolve the platform as your business changes.
Selected work
Platforms in production.
Outcomes, not screenshots.
A selection of systems we have engineered for enterprises where downtime is measured in headlines. Details are anonymized; the architecture and outcomes are real.

Testimonials
Trusted by the people
who are accountable.
Intercon didn't deliver a project. They delivered a platform our entire operation now depends on — and they stayed to make sure it kept running. The difference between a vendor and an engineering partner is night and day.

Security & compliance
Security is architecture.
Not an audit.
We build for organizations where a breach is an existential event. Every system is engineered to pass the audit your regulators will eventually run.
GDPR & Data Privacy
Data minimization, lawful processing, and right-to-erasure built into the architecture — not bolted on.
OWASP Secure SDLC
Threat modeling, SAST/DAST in CI, and dependency scanning on every commit. Security is a gate, not a phase.
Cloud Security
Zero-trust networking, least-privilege IAM, and encrypted everything — in transit, at rest, and in backups.
Enterprise Architecture
Network segmentation, service isolation, and defense in depth designed for regulated environments.
Secure SDLC
Signed commits, peer review, and reproducible builds. Every artifact is traceable to its source.
ISO-Ready Processes
Documented, audited, and repeatable. Our processes are ready for your compliance team to review.
