Omar Jesús Hernández Bastos
Lead Applied AI Engineer, FinTech. Valencia, Spain.
Today I design systems of AI agents that build software, and I run the engineers who work alongside them.
Get in touchAI, stage by stage.
How the industry moved, and what I built at each step.
- LLMs as a service6+ AWS-led workshops on Generative AI and Bedrock
- Tools and protocolsAn enterprise MCP server that connects agents to company resources, and MCP brought to banking
- AgentsAn online banking AI assistant and agent framework on AWS, and agentic lending for U.S. credit unions
- Harnesses and teams of agentsAn n8n-style orchestration platform for banking, and a team of agents I orchestrate on my own
- Models on my own machineLLMs trained and run locally, diffusion models, System One models
Agents that build systems.
I orchestrate agents that build whole systems. At work, a platform where orchestrator agents build and run banking workflows. On my own, Valdelena: ten steps from one sentence of mine to a tagged version, each with an owner, a deliverable and a control.
Valdelena
A medieval tower defense for the browser: 50 waves, a corrupted valley and two endings.
Built in seven days with a team of AI agents. This is how I work with them, from a sentence of mine to a tagged version, and nothing reaches players without my OK.
FeedbackMe
What I want, in my own words: a bug, an idea, a sentence after playing.
Only I decide product, spending and releases.
IssueOrchestrator
An issue with my literal sentence, marked as my feedback and waiting for triage.
The orchestrator is the only agent that talks to me; the others work from the issue.
PriorityProducer
Type, severity, priority, version and a single owner, within the hour.
It cannot grow a version by more than a fifth on its own: it brings me three options, through the orchestrator.
Brief and artArt Director and Technical Artist
A brief and a rubric first, then the image, model or texture made to them.
The Technical Artist does not approve its own work, and nothing is spent without my OK.
Pull requestProgrammer
One pull request per issue, with the typecheck and the unit test of that issue.
Programmers do not merge and do not deploy.
QAQA Lead
The delta test on the branch, screenshots when it is visual, then qa:verde or qa:rojo with the evidence.
The QA Lead does not write code and does not merge.
Merge and /next/Tech Lead
A read of the diff, the merge and a deploy to /next/, the test build.
It merges only with qa:verde, and never releases on its own.
My reviewMe
I play /next/ and say yes, or not yet.
Nothing reaches production without my OK.
ReleaseThe release script
The typecheck, a bot that plays 100 games of 50 waves per strategy, a determinism check and a smoke test when the interface changed, then the deploy to play.valdelena.com.
If one check fails, the script stops and nothing is published.
Tagged versionGitHub
An annotated tag and a release with its notes: v10.1, v10.2, v10.3.
Every version keeps its notes: what changed, how it was tested and what is still open.
Things you can open.
