Core competencies
What we are engaged to do
Systems integration & interoperability
API, middleware and interface development including REST, SOAP, HL7 v2, FHIR R4, CCDA, SFTP and event-driven messaging between clinical, administrative and financial systems.
CRM & ERP implementation
Requirements analysis, platform selection, configuration, custom module development, data migration and reconciliation, user training and post-deployment support.
Legacy modernization
Assessment and incremental replacement of end-of-life systems, including data extraction and migration, phased cutover planning and interim interface support.
Cloud architecture & DevSecOps
Infrastructure-as-code deployment on AWS and Azure, containerized workloads, automated CI/CD with approval gates, centralized logging, monitoring and incident runbooks.
Technology advisory
Architecture and security assessments, accessibility audits, technical due diligence, systems roadmapping and fractional technical leadership.
Technical depth
Boring technology, chosen on purpose
We pick tools your next engineer will already know and your security team will already have approved. Novelty is a cost, and where the data matters it is a liability.
Application
- TypeScript & Node.js
- React / Next.js
- Python
- .NET where the estate requires it
Data
- PostgreSQL & SQL Server
- Redis
- Managed warehousing
- Encrypted object storage
Infrastructure
- AWS & Azure
- Infrastructure as code
- Containerized deployments
- Automated CI/CD with approvals
Assurance
- Automated test suites
- Dependency & secret scanning
- Accessibility testing
- Centralized logging & alerting
Sensitive data
How we build when the data matters
These are engineering practices, not certifications. They describe how we design a system in the first week — which is the only point at which they are cheap.
We will sign a BAA before protected health information is discussed in any detail, and we hold any subprocessor we use to the same obligations.
- Least-privilege accessRole-based permissions, single sign-on, multi-factor authentication and session controls scoped to the narrowest job function.
- Encryption in transit and at restTLS 1.2+ on the wire, AES-256 at rest, managed key rotation, and no sensitive data written to logs.
- Complete audit trailsWho did what, to which record, at what time — queryable and exportable.
- Minimum necessary by defaultDe-identified data in non-production environments and field-level access limits in production.
- Accessibility as acceptance criteriaWCAG 2.1 Level AA verified with automated and manual testing, with the evidence handed over.
How we engage
Three structures, priced honestly
01
Fixed-scope project
A defined system, a written scope, milestone-based acceptance and a fixed fee. Best when the requirements are knowable up front and you need a hard number.
02
Dedicated capacity
A committed team for a set number of months against a rolling backlog. Best for longer modernization work where the destination is clear but the route is not.
03
Advisory retainer
Architecture oversight, vendor evaluation and technical review, monthly. Best when you have an internal team and need an outside read rather than more hands.
What transfers to you
At the end of an engagement you hold everything needed to run, change or move the system without us. That is a design constraint we accept up front, not a courtesy at the end.
- The source repository and its full history
- Infrastructure-as-code and environment configuration
- Credentials, cloud accounts and DNS under your ownership
- Architecture documentation and operational runbooks
- Administrator and end-user training material
Straight talk
What we do not claim
J&J Tech Group is a new firm. We would rather say that plainly than dress this page up with credentials we have not earned.
- We do not hold contract vehiclesIf a procurement requires one, we will tell you immediately rather than waste your time.
- We do not advertise certifications we have not completedIf a project needs a specific certification or clearance we do not carry, you will hear it from us on the first call.
- We do not invent past performanceReferences describe real work and are furnished on request. We will not pad a list with names we cannot stand behind.
- We do not quote what we have not scopedIf the shape of the work is not clear yet, we say so and propose a short paid discovery rather than invent a number.
What we do bring is careful engineering, a short line of communication, and a system you own outright at the end. If that is not enough for the requirement in front of you, we will say so and point you somewhere better.
