Backend engineer · Multi-tenant SaaS · Distributed systems · Data pipelines
Currently building billing infrastructure, workflow orchestration, and analytics platforms at 314e Corporation — a B2B SaaS company serving enterprise clients.
At my day job I own systems that run in production across 20+ enterprise tenants:
- Usage-based billing & metering — designed end-to-end with Lago across 8+ metering dimensions for AI workloads
- Workflow orchestration — durable tenant lifecycle automation with Temporal (onboarding: 4–5 days → 5 minutes)
- Embedded analytics — multi-tenant Apache Superset platform with per-tenant RLS and guest token architecture
- Data pipelines — Apache Iceberg + Kestra pipelines with tenant-aware partitioning on StarRocks
Outside work I build projects that push into distributed systems, AI integration, and real-time infrastructure.
