Software developer — Python & Rust. I build production software and open-source libraries, and teach modern web technologies.

Software developer with 12+ years of experience across Python, Rust, JavaScript and TypeScript and their main frameworks — from scalable APIs and AI integrations to web, mobile and high-performance open-source libraries. I care about clean, readable code and shipping things people actually use.

A security, audit and event observability platform built on a private, permissioned cryptographic ledger — a SIEM whose events are tamper-evident and independently verifiable. Observe · Detect · Audit · Prove: the same event flows through observability, detection, audit and cryptographic proof, in a single pipeline.

• 👁️ Observability — logs & events, errors, services, environments, endpoints, timeline, search & filters
• 🚨 Detection — brute force, suspicious IPs, new country, unusual admin/root activity, 401/403 and error spikes, threat intelligence
• 📋 Audit trail — actor, action, resource, timestamp, source IP, service, request ID, timeline and CSV export
• 🔏 Cryptographic proof — SHA-256 hash chain, Merkle proof of inclusion and integrity verification on every event
• 🏢 Private by design — permissioned ledger with multi-node Proof of Authority consensus, in your environment, no public blockchain
• ⚙️ Built in Rust — ECS normalization, host agent (zero code) and SDKs for Node.js, Python, Go and Java
• 🎯 Compliance — SOC 2, ISO 27001, LGPD, PCI DSS 10.5, NIST 800-53 AU-9, EU AI Act, ISO 42001

"Know what happened. Detect what matters. Prove what happened."

A productivity-focused backend framework for Rust that removes the "day-one tax" of standing up a real-world backend — scaffolding, conventions and code generation so you ship REST APIs in minutes, not days.

• 🏗️ Project scaffolding — production-ready structure with routing, database pooling and error handling out of the box
• ⚙️ CRUD generation — models, migrations, repositories, services, DTOs, handlers, routes and tests from a single command
• 🗄️ Multi-database — works with PostgreSQL, SQLite and MySQL
• 🔍 Transparent codegen — all generated code is readable, idiomatic Rust that you fully own and can edit
• 🔋 Optional batteries — admin interface, authentication, WebSockets and OpenAPI docs as opt-in modules
• 🦀 Built in Rust — Axum + SQLx + Tokio, a 10-crate modular workspace (2024 edition)

"Batteries-included velocity, the Rust way."

An educational, in-memory key-value database written in Rust — a Redis clone built from scratch with a focus on clean, readable code.

• 🔌 Redis protocol (RESP) — works with redis-cli and existing Redis clients, no changes needed
• 🗃️ Core commands — SET/GET, DEL, EXISTS, plus TTL & expiration (SETEX, EXPIRE, TTL) with background cleanup
• 💾 AOF persistence — buffered writes, periodic sync and AOF rewrite to keep history compact
• ⚡ Fast — ~155k ops/sec basic, up to 264k SET / 1.27M GET ops/sec with pipelining
• 🧱 Minimal stack — Rust (2024 edition) + Tokio as the only dependency, single binary, dual MIT/Apache-2.0

"Python simplicity. Rust performance."
