What I've built

Production-grade systems — each one solving a real architectural challenge.

flowcore Python

Distributed, durable and observable workflow engine. Pythonic DSL with decorators, hexagonal architecture, state persistence in PostgreSQL, automatic retries with exponential backoff, and worker crash recovery.

FastAPI Celery PostgreSQL Redis Hexagonal Arch
hex-auth-service Python

High-performance IAM solution using hexagonal architecture. Features O(1) token validation, Refresh Token Rotation, rate limiting, real-time security monitoring, and breach detection.

FastAPI PostgreSQL Redis Hexagonal Arch IAM
high-performance-task-queue Python

Resilient async microservice for payments and critical operations. Strong idempotency guarantees, fault tolerance patterns, and dead-letter queue handling for zero message loss.

Celery RabbitMQ Redis Docker
async-etl-framework Python

Modern, scalable asynchronous ETL framework built with Polars and HTTPX. Designed for high-throughput data pipelines with a clean, extensible plugin architecture.

Polars HTTPX Docker ETL
dentalcloud TypeScript

Complete SaaS platform for dental clinics. Interactive SVG odontogram, patient records, appointment scheduling. Delivered and running for a real client in production.

TypeScript Supabase SaaS Production
threat-intel-dashboard Python

Real-time threat intelligence dashboard for monitoring and visualizing security events. Aggregates indicators of compromise across multiple data sources.

Security FastAPI Threat Intel
secure-auth-api Python

Secure authentication API built with FastAPI. JWT lifecycle management, role-based access control, and production-ready security middleware stack.

What I specialize in

Deliberate architectural decisions for systems that are secure, maintainable, and truly reliable.

Authentication & IAM

Identity and Access Management systems with hexagonal architecture, OIDC flows, O(1) token validation, refresh token rotation, and real-time breach detection.

Distributed Systems

Resilient architectures with async message queues, idempotency guarantees, fault tolerance patterns, and dead-letter queue handling for critical operations at scale.

Scalable Backend Systems

Production-grade APIs and microservices with FastAPI, PostgreSQL, Redis, and Docker. Clean architecture patterns that make systems maintainable as they grow.

Security Engineering

Threat intelligence, security monitoring, vulnerability analysis, and defensive tooling. Building systems with security as a first-class architectural concern, not an afterthought.
