Software architecture for connected business
We build the operational backbone your company runs on — eliminating manual work, connecting fragmented systems, and giving your team the tools to move faster.
Custom Software Development
Custom CRM, SaaS platforms, ERP modules, legacy system modernization, and internal business tools — designed for real workflows, not template assumptions.
Off-the-shelf tools force your team to adapt to them. We build systems that adapt to your workflows, your data, and the way your business makes decisions — whether that means a new platform built from scratch, a CRM designed around your sales and service process, or a SaaS product engineered for your specific market.
- Custom CRM development and customer management platforms
- SaaS product development from architecture to deployment
- Legacy system modernization and application re-engineering
- Business-first architecture and data modeling
- React, Angular, Node.js, and Python full-stack
- Admin portals, dashboards and ERP modules
- Android and iOS mobile application development
- Role-based access and multi-user workflows
- API-ready systems built for integration and scale
- Security, documentation, and full code ownership
Private AI Integration & ML Development
OpenAI API integration, RAG systems, TensorFlow, Vertex AI pipelines, and LangGraph — connected to your real business data, not generic demos.
Artificial intelligence is only useful when it can safely understand the right business information. We structure data, APIs, access controls, and integration layers so AI can support real decisions — not just generic demos.
- OpenAI API and ChatGPT integration for business workflows
- RAG systems for internal document and data retrieval
- Private LLM deployment on your own infrastructure
- AI-ready data model design and structuring

QuickBooks & API System Integration Services
QuickBooks and Intuit integrations, REST APIs, middleware, webhooks, and system connections across your accounting, ERP, CRM, POS, and operational platforms.
Modern companies depend on many platforms that do not talk to each other. We build the API layers and middleware that connect accounting, CRM, ERP, POS, inventory, portals, payments, reporting, and legacy systems — so information flows automatically instead of being copied by hand.
- QuickBooks + Shopify integration: orders, payouts, refunds and taxes
- QuickBooks + HubSpot integration: deals to invoices, payment status in the CRM
- POS and inventory sync with QuickBooks
- Automated QuickBooks invoices, reports and data entry
- QuickBooks and Intuit Developer platform integrations
- ERP, CRM, POS and accounting system connections
- REST APIs, GraphQL, webhooks and middleware development
- POS, inventory and payment platform integrations
- DevOS: private corporate communications platform
- Website, portal and database synchronization
- Authentication, validation and integration documentation
Cloud Infrastructure & DevOps Services
Cloud migration, DevOps services, CI/CD pipelines, workflow automation, and scalable deployment infrastructure for growing businesses.
We handle cloud migration from legacy on-premise and fragmented hosting environments to AWS, GCP, or Azure — designing infrastructure that is secure, observable, and built to scale without constant manual intervention.
- Cloud migration from legacy infrastructure to AWS, GCP or Azure
- DevOps services: CI/CD pipelines, automated testing and deployment
- Infrastructure-as-code and environment management
- Workflow automation and scheduled business jobs
- Automated reporting, notifications and operational alerts
- Monitoring, uptime tracking and backup strategy
- Scalable cloud architecture for growing businesses
How We Deliver A structured, business-first engineering process — from diagnosis to continuous evolution.
Most software projects fail not because of bad code, but because of missing structure. At J14 Design, every engagement follows a proven six-phase model designed to eliminate scope creep, reduce delivery risk, and ensure that what we build actually fits how your business operates. We don't start coding until we understand your operation. We don't close a project until your team is ready to run it.
Diagnosis & Auditing (We map before we build.)
Every project starts with a deep technical and operational audit. We review your current systems, manual workflows, data silos, integration gaps, and reporting needs. This phase protects your investment — we define the right scope before a single line of code is written, so you never pay to build the wrong thing.
Architecture & Design (Your blueprint before your build.)
With a clear picture of your operation, we design the technical architecture: data models, API layers, user roles, system dependencies, and integration points. You receive a documented technical blueprint that defines exactly what will be built, how it will scale, and why each decision was made. No surprises mid-project.
Core Build (Functional modules, validated at every stage.)
Development happens in structured sprints with weekly demos. We build the foundational software layer by layer — core platform, integrations, dashboards, automations — so your team can review and validate real progress at every stage, not just at the end. Architecture-first means we engineer for scale from day one.
Rollout & Training (A launch your team is ready for.)
We deploy your system with a structured rollout plan — staged releases, data migration, QA testing, and live walkthroughs with your team. Every platform we deliver includes full technical documentation and hands-on training sessions so your people can operate it confidently from day one.
Optimization (We stay until it's right.)
The 30, 60, and 90 days after launch are where software proves itself. We monitor performance, resolve edge cases, fine-tune workflows, and incorporate real user feedback. This phase ensures your platform operates at full efficiency — not just technically, but operationally.
Continuous Evolution (Version one is where we start. Not where we stop.)
Business needs change. Your software should too. Through retainer or project-based engagements, we continue evolving your platform — adding AI capabilities, scaling infrastructure, connecting new tools, and building features that keep your operation ahead. Long-term partners, not one-time vendors.
Quick Answers
What kinds of companies do you work with?
Mostly small and growing businesses, founder-led ventures, and operations that need custom software, integrations, AI-ready systems, or stronger infrastructure. Many of our clients are in the United States or Latin America and need a team that can translate business priorities into technical execution — quickly and without hand-holding.
Do you only build full custom platforms?
No. Some engagements are full platforms. Others are a single integration, a dashboard, a reporting layer, an API, a cloud infrastructure improvement, or a modernization of one specific workflow. We define the right scope based on what the business actually needs — not on what makes the largest project.
Can you integrate with QuickBooks, ERP, CRM, or other business systems?
Yes. Integration is one of our strongest capabilities. We connect finance, operations, reporting, websites, internal platforms, customer systems, and third-party tools through REST APIs, webhooks, middleware, and structured synchronization processes. If two systems need to share data reliably, we can build the connection.
How fast can a project start?
Faster than most companies expect. One of our core advantages is that we move quickly once the diagnosis and architecture are clear — and we are structured to get there efficiently. We work with companies that need momentum, and we design delivery to show visible progress as early as the first phase.
Do you have experience with AI and machine learning?
Yes — and our approach is practical, not experimental. We work on AI-ready data models, TensorFlow workflows, Vertex AI pipelines, orchestration patterns, retrieval-based systems, and business-focused AI implementation. The goal is always to align AI with real workflows, usable data, and outcomes the business can measure.
What makes J14 different from a typical development agency?
Most agencies are optimized for design projects or marketing deliverables. We are a technical and business partner for companies that need architecture, systems thinking, serious integrations, and execution at an enterprise level. Clients come to us when the software has to support real operations — not just look professional on a screen.
Do you support clients after launch?
Yes. Our engagements do not stop at delivery. We support systems after launch through optimization, monitoring, cloud management, maintenance, new module development, additional integrations, and continuous evolution — as long as the business needs it.
What is the savings calculator for?
It helps leadership quantify the return on a software investment before committing to it. Instead of evaluating a project purely on development cost, the calculator estimates how process improvement, automation, integration, and better reporting translate into recovered time, reduced overhead, and operational gains. It makes the case for technology in business terms.
