Multi-language tour platform
First card-payment booking engine for a Seychelles tour operator. Inventory, channel manager, multi-language SEO.
Custom engineering
Production software,engineered to last.
Architecture-first builds for teams that need ownership, scale, and clean handoff.
Enterprise applications, financial platforms, booking systems. React, Vue, TypeScript, Node.js, PostgreSQL — built by senior engineers.
Shipped in production
Systems that clear real transactions.
Seypro builds custom software — from MERJ Exchange (a regulated securities exchange) to multi-language booking engines with card payments. React, Vue, TypeScript, Node.js, PostgreSQL. Full code ownership, deployed on your infrastructure.
Engagement flow
seypro@terminal:~
We build custom software — web applications, SaaS platforms, booking systems, financial tools, and enterprise dashboards — using TypeScript, React, Vue.js, Node.js, and modern cloud infrastructure. Full-stack, from database architecture to pixel-perfect frontend, deployed on AWS, Azure, or Google Cloud with CI/CD pipelines and auto-scaling built in from day one.
Our stack is opinionated: shared TypeScript types across frontend and backend, PostgreSQL or MongoDB depending on the data model, REST or GraphQL APIs, comprehensive test coverage, and security-first architecture following OWASP Top 10 guidelines — backed by our dedicated security and compliance practice. You get clean git history, documented code, and systems that future developers can maintain without calling us. Source code is yours, always.
We've built systems that process real transactions, serve regulated industries, and run in production for years without critical incident. MVP in 4–8 weeks, multi-year platform with a dedicated team, or systems augmented with AI and automation — the engineering bar is the same. Agile sprints, weekly demos, architecture designed for what comes next.
The stack
Chosen per project. Not bolted on by default.
React, Vue, TypeScript, Node.js, PostgreSQL. Frontend, backend, data, infra — owned by one team.

What we build
We don't ship dashboards. We build securities exchanges.
Architecture designed for your data model, compliance posture, and the scale you'll actually hit.

Before you ask.
Modern stack: React/Next.js, Vue/Nuxt frontends. Node.js, Python backends. PostgreSQL, MongoDB databases. AWS, Vercel cloud deployment with CI/CD.
Yes. All source code is delivered in your GitHub or GitLab repository with permissive licensing. You own 100% of the intellectual property.
Yes. 30 days post-launch support included. Then monthly retainers for maintenance, updates, features, and technical support — scoped to your needs.
Security-first: encrypted transmission, OAuth 2.0/JWT auth, RBAC, regular audits, GDPR compliance, secure cloud infrastructure. All code security-reviewed before deployment.
MVPs launch in 4–8 weeks. Full enterprise systems in 3–4 months. We work in 2-week agile sprints, so you see measurable progress continuously.
Yes. We integrate LLMs (OpenAI GPT-4, Claude, Gemini), build custom AI agents, implement intelligent document processing, and wire automated workflows into production applications.
Absolutely. We augment teams, provide technical leadership, conduct code reviews, or own specific modules. Seamless integration with your workflow.
Absolutely. We build custom content management systems tailored to your exact content structure, workflows, and permissions. Far beyond WordPress limitations.
Next.js for React ecosystems and SEO-critical applications. Nuxt 3 for Vue teams or when Vue design systems already exist. We choose based on your technical requirements and team preferences.
AWS and Vercel by default. We use infrastructure as code where appropriate and implement cost/performance guardrails. Applications are deployed to your own cloud accounts for full ownership.
