Backend engineer · Buenos Aires

Computer Engineer from the University of Buenos Aires. I spent 16 months at LambdaClass building blockchain infrastructure in Rust, Go and Elixir, around 350 pull requests, all public. Now I'm looking for backend roles, mostly Python and Go.

aligned_layer

RustPostgreSQLDockerPrometheusGrafana

Reliability work on a service that aggregates ZK proofs and pays fees on-chain.

  • A payments poller that resumes from its last block after a restart
  • Retries that bump the fee when a verification times out
  • Daily usage limits per user
  • Metrics and dashboards with Prometheus and Grafana

zk_arcade

ElixirPhoenixReactPostgreSQLSolidity

A full web product: games that generate ZK proofs, with points, a leaderboard and NFTs.

  • Moved the WebSocket connection to the backend, so it survives the user closing the page
  • Signature-based authentication, checking each request against the session address
  • A poller that reads contract events and keeps the database in sync with the chain
  • Database schemas, leaderboard and stats pages

eigensdk-go

GoConcurrencyRPCTesting

EigenLayer's official Go SDK, a public API other teams build on.

  • Worked on the v2 redesign: concurrent entities and a separate RPC server
  • Tests for the contract readers and writers
  • A common error interface across the client modules
  • Moved boilerplate from the example services into the SDK

ethrex

RustEVMTesting

LambdaClass's Ethereum client. I worked on the virtual machine, with the official Ethereum Foundation test suite as the target.

  • Most of the cryptographic precompiles (ecrecover, ecpairing, point evaluation and others)
  • Gas accounting fixes, like a call cost that charged too much on every value transfer
  • Integrated the Ethereum Foundation test suite into the project

reservoir-pressure-web

PythonFastAPIReactTypeScriptPostgreSQL

Web app for my final thesis, built with two classmates. An engineer uploads the production history of an oil field and gets the estimated pressure from an ML model.

I built the pluggable model architecture (LSTM, Ridge, XGBoost), the input validation, the example case loader and the CI with coverage.

unipoll

ElixirPhoenixReactTypeScriptPostgreSQL

Real-time polls with access levels, from public to invite-only with authentication.

p2pal

GoWebRTCRedisDockerPrometheusGrafana

CLI to send files directly between machines over WebRTC.

The server only brokers the connection with short-lived join codes in Redis; the files never touch it. Supports directories, resume after an interruption and SHA-256 checks.
