You will get Scalable Backend & API Solutions with Monetization and Security
Project details
You will get a professionally architected backend or API solution that is secure, scalable, and business-ready. With expertise in Node.js, TypeScript, Docker, MongoDB, Redis, and Stripe integrations, I deliver APIs that are not only technically robust but also monetizable and marketplace-ready. My work stands out because I combine backend engineering with DevOps automation, developer-friendly documentation, and SaaS monetization strategies. Whether you need a simple API, a scalable microservices setup, or a blockchain fraud detection engine, I ensure your project is delivered with professional polish, clear onboarding, and long-term reliability.

About Evans
Fullstack Developer | Node.js, Python, Docker & SaaS Solutions
Nairobi, Kenya - 7:12 am local time
Stop building brittle infrastructure. Start deploying a workforce.
Most companies lose thousands of dollars every month because their "automation" is linear and fragile. When an API changes or a server flickers, the system breaks, and your developers stop building features to become "digital janitors."
I am here to fix that.
As a Software Architect and the founder of Nexus Core, I specialize in building Agentic and Self-Healing Infrastructure. I don’t just set up servers; I build resilient ecosystems that monitor themselves, adapt to errors, and scale autonomously.
Why work with me?
Native-AI Integration: I integrate Agentic Workflows into your DevOps cycle to handle complex tasks that traditional tools like Zapier or standard Cron jobs can’t touch.
Backend Mastery: Expert in FastAPI, Node.js (NestJS), and Prisma, ensuring your infrastructure and your application code communicate perfectly.
Cloud Infrastructure: Pro-level management of AWS, GCP, and DigitalOcean, utilizing Docker and Kubernetes for containerized stability.
Fintech & Payments: Extensive experience with Stripe and M-Pesa API integrations, focusing on secure, high-velocity financial transactions.
My Technical Stack:
Languages: Python (FastAPI), JavaScript/TypeScript (Node.js, React).
DevOps: Docker, Kubernetes, Terraform, CI/CD (GitHub Actions, Jenkins).
Databases: PostgreSQL, MongoDB, Redis.
Specialty: Agentic AI Orchestration, Self-Healing Systems, and API Economy Research.
The Result: A 99.9% uptime, reduced manual overhead, and a development team that is free to focus on growth rather than maintenance.
