Mujahid Masood
Senior Software Engineer — Backend & Applied AI · Germany
Over a decade of full-time experience building JVM backend systems — Kotlin, Java, Quarkus, Spring Boot — on AWS and Kubernetes, including IoT platforms (AWS IoT Core, MQTT, LoRaWAN). Currently at beyonnex.io. Alongside enterprise work, I design and ship applied-AI systems: multi-agent fleets with coded safety guardrails, LLM intent firewalls, and agent systems whose authority is bounded in code.
Selected AI Projects
- BouncerAI — an intent firewall for LLM agent fleets: a policy engine plus an AI intent judge that catches hijacked-intent attacks tokens can't see.
- Keepsake — a voice-first memory companion for a person living with dementia, run by a fleet of ten agents where every safety-critical decision is made by code, not a prompt.
- Meshyay — a commerce platform whose back office is run by AI agents bounded by an explicit autonomy register in code, with autonomous USDC supplier payouts via Circle Agent Wallet.
