POSTALRIOS / PUBLISHING WORKFLOW01

FROM AN IDEA TO A POST
A little less friction.
A little more creating.
Workflow illustration
A complete publishing workflow
Turning a topic into a useful post involves more than generating
text. Postalrios brings planning, generation, editing, review,
and scheduling into a connected workflow.
Visit Postalrios ↗
- The product
-
Topic planning, AI-assisted posts and carousels, draft review,
scheduled publishing, and a history of what was shared.
- The engineering
-
A Next.js and TypeScript interface, typed APIs, PostgreSQL
storage, and background workers for generation and publishing.
- Beyond the interface
-
The release pipeline builds and tests versioned images, checks
them in an isolated end-to-end environment, and switches
between blue and green application stacks.

Making the trade-offs measurable
A language model carries a cache of earlier tokens as it
generates an answer. This project asks what happens when that
cache is reduced, and which information is worth keeping.
Talk about this work ↗
- The question
-
How do different token-retention strategies affect answer
quality, generation latency, and GPU memory use?
- The experiment
-
A full-context baseline is compared with recency,
attention-based selection, and policies that combine relevance
with diversity.
- The discipline
-
Runs record their configuration, per-example results, and GPU
metrics. This is experimental benchmarking, not a claim of a
universal speedup.

Software for the rhythm of a studio
Acumyoga brings the recurring work of a yoga studio into one
application: organizing classes, managing memberships, and
welcoming participants.
Visit the studio ↗
- For the studio
-
Administrators manage events, attendee lists, customer
memberships, remaining entries, and expiration dates.
- At the door
-
QR-based attendance connects check-in to membership entries,
while a public calendar makes upcoming classes easy to find.
- The implementation
-
A Flutter interface connects to a Django backend and
PostgreSQL database, with separate public views and
authenticated administration.

Deployment flow
Owning the path to production
The infrastructure project supports the apps I build. It makes
host setup repeatable and keeps deployment, certificates, logs,
and monitoring manageable.
Talk about this work ↗
- Repeatable setup
-
Ansible playbooks manage hosts and services. Application
repositories own their build, test, and deployment commands.
- A deliberate release path
-
Jenkins runs builds on the appropriate host, with Docker
providing consistent runtime environments and versioned
application artifacts.
- Knowing what is happening
-
Prometheus, Grafana, Loki, and Alertmanager provide metrics,
logs, dashboards, and alerts across hosts and applications.
