ENGINEER

hi, I'mSol Soletti

I take ideas from a hunch to production: AI-first, and with the evidence on the table.

    Teramot · Argentina

    Dec 2025 → now

    Two products, end to end, and the lead on the newest one.

    Teramot Beacon

    I lead work across the node, the protocol and the UI: the slice cache, the MCP server, dashboards, monitors and data-quality checks. I explore new approaches early, prototype them, and take the ones that hold up to production.

    Teramot data platform

    Backend engineer on Teramot's main platform: Go services, business logic and internal processes, plus the quality, maintainability and performance work that keeps it running.

  2. IT Intern · AI agents lead

    Argental S.A.I.C. · Granadero Baigorria, Santa Fe

    Aug 2025 → Dec 2025

    My first technical role, five months long, and I led Busquetti, Argental's multi-agent AI product advisors, building most of it myself: one agent per machine line, from ovens and proofers to mixers and dividers. I gathered the product knowledge, improved the agents, and migrated the existing system built on OpenAI agents to a RAG pipeline I programmed myself.

a game

SunMoon

A two-player cooperative puzzle platformer about the only hour two lovers can share.

Once in a long while the Sun and the Moon meet, and the world goes dark. Sun walks through sunfire; Moon wades through moonlight. Each one dies in the other's element, and a chamber only opens when each of them stands at their own door. It's a game about leaning on someone, and about the moment you have to let go.

projects

What I build on my own.

TypeScript

nats-trail

Agent-native observability for NATS and JetStream.

A web UI, a CLI and an MCP server over one bounded query engine. Follow a request_id across four streams without opening four terminals, and let Claude look at production, read-only.

A curated photo archive: moments, places and memories arranged with the patience of an exhibition. Gallery, collections, archive, favorites and friends.

legios

What I build with Valen.

Legios is the name we give to the developer tools and games Valen and I build together: tools that look at what's already on disk before calling a model, from a deterministic map of every repo to a spec an executor carries all the way to a verified PR. Private work is described as capability, never shown as code.

legios.com.ar
"Wrong memory is worse than no memory."
cartographerprivate

Charts a repo before anyone sails it.

A deterministic symbolic context artifact plus a symbol index on tree-sitter and SQLite. Zero model tokens.

I lead it private
pipelineprivate

Approved spec, free executor, verified PR.

From an approved spec to a verified PR, with per-run isolation on ECS Fargate.

How much quota you have left, in every agent account on the machine.

Teramot Beacon

Business questions in plain language, no warehouse.

Read the post

A node that answers business questions by pulling only the slice of data each question needs into DuckDB, inside the customer's own network. One process, one container, any cloud or on-prem. I'm the main author of the node, the UI and much of the protocol.

  1. question
  2. planner
  3. slice
  4. DuckDB
  5. answer + SQL + provenance

Slice cache

Validated by source version, not by TTL. An unfiltered aggregate can't serve a filtered question.

TLP protocol

A versioned, cloud-agnostic contract: dashboards, monitors, artifacts, refresh and scheduling.

MCP server

Beacon as tools for agents, plus the node's own assistant loop.

Dashboards & alerts

Cross-filtering, small multiples, monitors and stale-data alerts.

Data quality

Catches join fan-out, duplicates, mismatched keys and mixed currencies.

Next.js UI

Every answer with a narrative, a table, an auto-chart, the SQL and cache provenance.

blog

What I've been up to.

Notes, videos and posts: dated decisions, things I broke and how I fixed them.

See all

A cache is a theory about what will be asked next.

Once we stopped asking how old is this and started asking is this still true, the code got shorter and the answers got more honest.

It knows nothing the business never cared about, and everything it does know, it knows because someone asked.

note

A Flag Is Not a Guarantee

How nats-trail started as yet another NATS GUI and ended up as a place where an agent can look at production without being able to touch it.

Eight Rows, Not Twelve Million

The cache behind Teramot Beacon: pull only the slice a question needs, and invalidate by source version instead of a TTL.

profile

I'd rather try it than wonder.

I'm an Information Systems Engineer (UTN) and an Engineer at Teramot, where I lead work end to end, from protocols and data engines to the interfaces people actually use. I work AI-first: I explore early, prototype fast, measure honestly and keep only what holds up. I take the risky idea seriously enough to test it. Outside work, Valen and I build developer tools and games together under the name Legios.

Explore before deciding

I'd rather prototype three ideas in a week than debate one for a month. Whatever survives the evidence gets built properly.

./ai-first

AI-first, with guardrails

Models and agents are part of how I design and build, not an add-on. Always with typed contracts, bounded reads, and no way to break production.

./lead

Lead by building

I set direction by shipping: protocols, specs and working software that others can pick up, trust and extend.

An AI-first system, a risky idea worth testing, or a co-op game: if you've got something going, write to me.
