Software Engineer AI Builder
I'm Emmanuel Joshua_
A
Software Engineer building production-ready AI products.
I build production-minded AI products, agentic workflows, backend services, and full-stack systems that are useful beyond the demo. Full-stack products, agentic workflows, and reliable cloud systems—built to work beyond the demo.
01. about
I build software and AI products that hold up in real environments.
I'm a Software Development Engineer II at Amazon, building high-availability AWS applications, backend services, data workflows, and operational tooling. Security is the domain; software engineering—performance, reliability, observability, and automation—is the core discipline.
My current focus is AI engineering: production-ready AI products and agentic workflows, supported by the full-stack software that makes them useful. EchoFocus turns text, files, photos, and live recordings into synchronized audio, transcripts, summaries, and searchable history.
I'm completing an MS in Computer Science at UT Austin with a Machine Learning and AI focus. I'm most interested in the engineering that makes intelligent software reliable, observable, and useful in production.

07. focus areas
What I work on
The profile I want this site to communicate: a software engineer who can build AI features, ship the product around them, and keep the system reliable after launch.
Full-Stack AI Products
Building user-facing AI tools with usable interfaces, APIs, auth, data storage, transcripts, summaries, search, and production-minded workflows.
Agentic Workflows
Designing systems that combine LLM reasoning with deterministic workflow steps, integrations, observability, and human review where it matters.
Backend & Distributed Systems
Designing resilient services, data models, and processing paths that hold up under real load and remain understandable during operations.
AWS & Operational Reliability
Building cloud applications with monitoring, alarms, logging, automation, and support tooling that help teams operate production systems confidently.
Research & Technical Writing
Turning engineering work into clear research, articles, and mentorship for people building software, AI systems, and security-focused platforms.
