What We Build for You
Full-stack FinTech engineering — from AI/LLM layers and blockchain payment rails to cloud-native SaaS platforms and compliance-ready data architectures.
Hybrid AI / LLM Chatbots
Two-model architecture pairing a local Mistral7B for sensitive data with OpenAI cloud for general queries — ensuring zero sensitive information leaves your environment while delivering enterprise-grade AI capability.
Crypto & Blockchain Payments
Full-stack crypto payment infrastructure including Coinbase API integration, Bitcoin Full Node, Lightning Network for instant micropayments, and eCommerce plugin deployment — from concept to 8-month MVP.
Platform Modernisation & SaaS
End-to-end product development for FinTech SaaS companies — microservices on AWS Lambda/ECS, React Native mobile apps, .NET Core APIs, and portfolio management systems built to production standard.
Compliance-Grade Security
Secured data zone architecture isolates sensitive financial data from external systems. GDPR and CCPA compliance baked into data flows — not retrofitted. Vector DB (FAISS) enables RAG without data leakage.
