Cyprian Tinashe Aarons is a Senior Full-Stack & AI Engineer with 6+ years architecting scalable systems, leading engineering teams, and shipping GenAI workflows with LangChain, LangGraph, and robust backend infrastructure.
Born and raised in Zimbabwe. Graduated from the Harare Institute of Technology in Software Engineering, which is where the obsession with backend systems, distributed infrastructure, and applied machine learning started.
The last six years have been spent leading engineering teams, building founder-led products, and scaling an AI platform at Africai past 20,000 active users as CTO. Along the way, contract work with teams in the UK (CST, Vanti) and the US (Coindraw) kept the stack honest across backend, frontend, Web3, and IoT.
Today I work as an independent Senior Full-Stack & AI Engineer for founders who need AI-built apps rescued, launched, secured, automated, or upgraded with production-grade AI. The ambition is simple: useful software that survives real users, not just demos.
Production AI microservices with FastAPI and LangChain. Automated engagement improved 25%, data pipelines 40%, and deployment cycles cut 50% through CI/CD and containerisation.
Led an engineering team building an AI platform that scaled to 20,000+ active users with 99.9% uptime. Cut API response times 35–75% and integrated Stability.ai and OpenAI into production systems.
Backend systems supporting 10,000+ concurrent users, secure payment and withdrawal infrastructure on Node.js + PostgreSQL, and high-traffic crypto operations.
Reduced processing times 80% for critical internal workflows. Improved API response times from 500ms to 200ms by refactoring backend flows and frontend data fetching.
Managed a distributed team of 20 developers building blockchain applications, Web3 tools, and founder-led product systems. Scaled decentralised infrastructure to 10,000 concurrent users using Node.js microservices and Redis caching.
Built real-time Vue.js interfaces for IoT applications, syncing operational data from Golang-based hardware backends into high-performance dashboards.
Directed a cross-functional team of 10 across eCommerce and SaaS products. 100% on-time delivery and 40% fewer production incidents via standardised CI/CD and automated testing.
