What I work on

DevOps and automation — Ansible roles, Helm charts, container images and release pipelines, each with a test that runs it for real. Linux and systemd, Prometheus metrics, incident response. Blockchain infrastructure — a resilient JSON-RPC gateway, wallet and permission monitors, smart contracts on KleverChain, and fixes sent upstream to node and SDK code. Backend systems in Go — services that ship as a single static binary with no runtime dependencies, SQLite with full-text search, systemd deployment. Full stack in PHP — my day job on a healthcare platform in production: registration and permission flows, scheduling, payments, reversible database migrations. Quantitative development — trading strategy research and backtesting on QuantConnect, risk modelling and predictive models on financial time series. Data automation — collection bots, scraping, pipelines and internal tooling on Linux and systemd.

Every repository below is public, tested and green in CI. Client work and my own tooling (iode, sentinel) stay private.

Selected work

permwatch — shows who can sign for a KleverChain account, flags risky permissions and alerts by webhook or Telegram when they change; also watches spending-limit vaults. Ships with an Ansible role and a Helm chart, each tested end to end, and was verified against testnet. Go.

rpcgate — resilient Ethereum JSON-RPC gateway: failover, circuit breakers, routing by block height, safe caching and per-provider metrics, proven with chaos tests. Go.

chainwatch — watches wallets for risky ERC-20 approvals and drain patterns across EVM chains, reorg-safe, with Sign-In with Ethereum and one-click revoke through MetaMask. Go, Solidity, React.

klever-contracts — smart contracts for KleverChain: a KLV vault with a per-period spending limit, deployed and exercised on testnet, with a toolchain setup that builds. Rust.

tickguard — validates live crypto trade feeds (Binance, Kraken, Mercado Bitcoin), tells known gaps from silent ones, writes clean QuantConnect LEAN data and audits existing LEAN datasets. Go.

costbasis-br — Brazilian crypto cost basis with exact arithmetic; tax rules are dated, cited data instead of code. Go.

Quantitative research — strategy simulation and backtesting on QuantConnect, with predictive modelling in Python and R.

Editalis — WhatsApp alerts for Brazilian public service exams, filtered by each subscriber's profile, with billing and LGPD consent. Python, FastAPI.

bounty and news — a GitHub bounty finder that filters out bounty farms, and a curated weekly magazine. Go and PHP.

Open source

21 pull requests merged in Binance, QuantConnect, Klever, Solana and Linux Mint, each with a test that fails before the fix and passes after it.

Currently

Software Engineer at TIIX — a health and services platform (tiix.com.br). I work on the PHP portals for clients, professionals and brokers: registration and permission flows, scheduling, payments, and the shared foundation beneath them. Legacy PHP in a WordPress-based ecosystem, with reversible MySQL migrations.
