Service architecture
Boundaries, event flows, background jobs, ownership models, and migration paths that reduce operational drag.
Backend Developer
I design APIs, distributed systems, observability pipelines, and high-throughput services that stay calm under real production load.

01
API contracts
Versioned, testable, and friendly to product teams.
02
Reliability
Timeouts, queues, retries, idempotency, and alerts.
03
Performance
Measured bottlenecks, lean queries, and predictable latency.
Systems Expertise
Practical backend work across the path from product idea to durable service.
Observability
Metrics, logs, traces, dashboards, and alert rules that expose causes instead of producing noise.
Data performance
Index strategy, query plans, cache design, and consistency choices tuned to product behavior.
Selected Backend Projects
Replace these with your own work as we personalize the site.
01
Payments Webhook Platform
Idempotent processing, replay tooling, signature verification, and dead-letter recovery for critical billing events.
- Node.js
- Postgres
- Kafka
02
Multi-tenant API Gateway
Rate limits, tenant-aware routing, audit logs, and contract tests for partner-facing integrations.

03
Analytics Ingestion Pipeline
Buffered event ingestion with backpressure, schema validation, partitioned storage, and real-time health views.
- Python
- S3
- DuckDB
Built for the uncomfortable parts of production.
The strongest backend work is usually invisible: fewer incidents, clearer APIs, faster deployments, and systems other engineers can reason about when pressure is high.
