Custom Software Development Services
Centric Byte is a custom software development company covering everything from the screens to the servers behind them: web applications, subscription software (SaaS), websites and online stores, dashboards, internal tools, APIs, and AI features. We work with startups shipping a first product, growing companies that need more engineering capacity, and established businesses updating software they've outgrown.

Web Application Development
Customer portals, platforms for business customers, booking systems, and the internal systems behind them, built on Next.js and React with Node.js and PostgreSQL underneath. You own the code outright.
What's Included
- Screen design, with clickable Figma prototypes
- The part users see, built with Next.js or React
- The part behind the screens, built with Node.js or NestJS
- Sign-in and access control
- Hosting and automated releases (CI/CD)
SaaS Product Development
Everything between the idea and your first paying customers: a backend that keeps each customer's data apart, Stripe or Paddle billing, access by role, onboarding, and an admin area your support team can actually use. So you can spend your time on customers and revenue, not technical fires.
What's Included
- Product scoping and technical planning
- Separation of each customer's data (multi-tenant design)
- Subscription billing (Stripe/Paddle)
- Access by role
- Admin dashboard
Website & E-commerce Development
Business websites and online stores, static or dynamic, with or without online payments. We have built for agencies, consultants, insurance agencies, doctors, clinics, hospitals, travel agencies, creators, factories, and e-commerce stores, including stores that use Sanity as the admin panel.
What's Included
- Static or dynamic architecture, whichever fits
- Admin panel for content (Sanity or custom), no code needed to use it
- Appointment, inquiry, and contact forms
- Online payments through a gateway (optional)
- SEO foundations built in
- Post-launch support, with scope agreed before we start
Dashboards & Analytics
Custom dashboards that turn raw tables and data feeds into something a busy person can act on. Filters, click-through detail, exports, and access by role, so a manager sees everything and a client sees only their own numbers.
What's Included
- Connections to your data sources
- Custom charts and tables
- Filters, date ranges, and click-through detail
- Export to PDF/CSV
- White-label options
Internal Tools & Automation
Internal tools, admin panels, custom CRMs, ERP and supply chain systems, and automation workflows that follow how your team already works. Connected to the tools you use now, with permissions and activity logs from day one.
What's Included
- Discovery workshop to map how your team works
- Workflow automation (approvals, notifications)
- Third-party integrations (Slack, email, and more)
- User permission management
- Activity logs showing who did what
AI & LLM Integration
OpenAI and Anthropic Claude built into real products: answers from your own documents (RAG), document processing, smart search, chatbots, and AI agents. We test against your own data, watch what each request costs, and review what the model can see before it sees it.
What's Included
- OpenAI / Anthropic Claude API integration
- Answers drawn from your own documents (RAG)
- Document processing
- AI chatbot UI and backend
- AI agent workflows
API & Backend Engineering
