Description

Senior full-stack engineer and software architect. I design and develop end-to-end enterprise SaaS platforms in regulated and security-sensitive sectors — fintech, healthcare, energy, logistics.

Some platforms I have architected and developed:

•Cross-border payments (fintech) — 14 microservices platform integrated with PAPSS (pan-African settlement): KYC, AML, FX, reconciliation, USSD, audit. Java / Spring Boot, 1,000+ tests.

•Pharmaceutical data integrity (FDA compliant) — cryptographically verifiable audit trail engine and real-time compliance monitoring. Python / Rust.

•Smart energy management — multi-tenant enterprise energy monitoring SaaS platform. TypeScript / React.

•Supply chain risk profiling — zero-trust (mTLS), multi-tenant, real-time risk assessment SaaS. Go.

•AI Automation (n8n / agents) — business automation workflows, voice quote generation for construction.

What I can do for you:

•Architecture and development of complete SaaS platforms (multi-tenant, secure)

•Backend: Java/Spring Boot, Python, Go, microservices, REST APIs

•Frontend: TypeScript, React

•Infrastructure: Docker, Terraform, CI/CD, zero-trust architecture

•Compliance & security: KYC/AML, audit trails, GDPR, regulated industries

•AI Automation & LLM integration (n8n, agents)

Stack: Java, Spring Boot, Python, Go, Rust, TypeScript/React, PostgreSQL, Docker, Terraform, microservices, event-driven architecture.

Rigorous approach: security by design, tested, maintainable, documented code. Available for remote work and in Île-de-France.

TJM: €650 (negotiable depending on the mission).
