$25k this year is about getting my money up AND MY FUNNY UP. I’d like to thank my days ones Kubernetes, Redis and Cloudflare. I’d also like to give a special shout out to my opps… they keep designing bad architecture and I just get to clean it up.

Cover image for Building the technical foundation for

Building the technical foundation for Otonix, an AI-native IT Operations Platform I worked on the engineering side of Otonix, an autonomous IT operations platform built on agent-first, task-specific AI agents that monitor, triage, remediate, and escalate IT operations, instead of a chatbot bolted onto legacy RMM/PSA tooling. What the build involved: 🔹 Architecting the platform around four core agent capabilities: Monitor, Triage, Remediate, and Escalate. 🔹 Building the policy-guardrail layer that constrains automated actions and gates anything touching regulated systems or irreversible changes. 🔹 Implementing the audit trail: a signed, searchable, exportable log of every agent decision and action. 🔹 Working with a signal-ingestion pipeline (endpoints, servers, network, IoT) feeding into the triage/remediation flow. Python/FastAPI, Node.js, React, PostgreSQL, Docker, n8n, Kubernetes I build backend systems and full-stack platforms for technical products. Especially where reliability, auditability, and guardrails matter as much as the automation itself. If you're building something in a similar space, let's talk. 📩 mosesmorrisdev@gmail.com | github.com/Moses-Morris

Cover image for An auditor losing internet shouldn’t

An auditor losing internet shouldn’t mean losing their work. At Cornell’s DECA Lab, I built web and mobile audit tools for people working in places where connectivity is unreliable. That constraint shaped the product: auditors needed to start an assessment, save progress, leave, and come back without starting over. My work covered the mobile app, backend APIs, role-based access, and reporting, using React Native, Next.js, FastAPI, and PostgreSQL. The most interesting engineering decisions were around what happens between screens: saving drafts, syncing after a connection returns, and protecting data when a workflow gets interrupted. It’s the kind of work I enjoy: taking a messy, real-world process and turning it into software people can depend on. If you’re building an internal tool, dashboard, or mobile product with workflows like this, I’d love to hear about it.
