The resilient systems behind reliable software products.
REST APIs, asynchronous queues, background workers, database architectures, and third-party integrations engineered for high reliability.
What I can build.
- ✦High-Throughput Asynchronous REST & WebSocket APIs
- ✦Relational Database Architecture & Optimization (PostgreSQL)
- ✦Asynchronous Job Queues & Background Worker Infrastructure
- ✦Secure JWT / OAuth2 Authentication & Session Management
- ✦Webhook Consumers with HMAC Signature Verification
- ✦Semantic Caching & Rate-Limiting Layers
- ✦Containerized Cloud Deployment (Docker / AWS / Linux)
What you get.
- Sub-100ms API response times with async worker delegation
- Robust relational database schemas with migrations and connection pooling
- Defensive retry handling with exponential backoff on external service glitches
- Structured JSON logging (Structlog) and distributed tracing (OpenTelemetry)
- Production Docker containerization and automated deployment scripts
From fast build to complete system.
You don't always need a massive enterprise build. We scope the software to match your exact timeline and stage.
Focused Working MVP
Design and implement a fast, secure backend service or microservice in 1–2 weeks.
Production Infrastructure
Complete backend infrastructure: API layer + PostgreSQL + Redis queues + worker clusters + observability telemetry + CI/CD automated test suite.
Keep your current tools. I'll build around them.
Decoupled, observable backend architecture built for zero-downtime operations.
Relevant working systems.
Real implementations that demonstrate this capability in production.
RealEstate AI Sales OS
Stateful multi-agent workflow engine that orchestrates the real estate sales lifecycle through a directed graph with checkpoint-based persistence, MCP tool abstraction, and human-in-the-loop interrupts.
A production-grade multi-agent system demonstrating stateful workflow orchestration with checkpoint persistence, MCP tool abstraction for integration decoupling, LLM reliability engineering (structured outputs, model fallback, guardrails), and automated evaluation—reducing per-workflow LLM calls by 40% through agent consolidation and deterministic routing.
ThreadBase
LLM-powered content scheduling platform with async job orchestration, idempotent scheduling, and full audit trail observability.
A production-grade content scheduling platform achieving reliable job execution with complete lifecycle observability, efficient LLM cost management through semantic caching, and secure media delivery via signed URLs.
SpecOS
A development platform that synchronizes architectural specifications with production code through automated GitHub integration.
A development tool achieving synchronized repository states and low-latency architectural scaffolding.
Inbound Lead Engine
Production-grade async lead processing with AI intent inference and SLA enforcement.
Full-stack containerized environment. Zero ingestion wait-time. Automated state escalation for hard failures.
Under the hood.
Architectural details and engineering decisions behind this system.
Asynchronous Concurrency
FastAPI with native AsyncIO handles thousands of concurrent requests with minimal RAM overhead.
Redis pub/sub and task queues ensure non-blocking user experiences during heavy computation.
Defensive programming with Tenacity retries and exponential backoff protects against external API outages.
