A shared agentic backend — tools, skills, and authorization — powering both a chat-based operations harness and the voice layer, in the spirit of Claude Code, built on a three-generation framework migration.

A modular-monolith platform core — multi-tenant, event-driven, with fine-grained authorization, Temporal-based workflow orchestration, and a single gRPC surface for web and mobile.

Took a financial election-processing product from 0 to 1 — architecting its ACID-compliant data layer, authentication, and authorization — then years later scaled its election-submission path for two opposite load shapes: high-concurrency retail elections and high-fan-out institutional bulk submissions.

A tenant-aware knowledge system — retrieval, ingestion, and self-serve source configuration — with an evaluation harness built in from the start.

Cross-cutting performance and reliability engineering across a four-datastore stack (MySQL, Elasticsearch, Cassandra, Redis) — from query-level fixes to pipeline redesigns that unblocked an infrastructure upgrade.

Founded and scaled a real-time financial-reporting pipeline from a v0 Airflow/Kafka/Postgres build to a pre-aggregated system of daily/quarterly/rolling Postgres tables computed asynchronously by a worker pool, handling GA-scale query traffic.

A multi-provider realtime voice architecture with dynamic routing, pre-call failover, and profile-aware behavior.

A self-serve BI layer for IMSecurities — customers compose their own queries over curated datasets and link them into dashboards, with role-based access per dashboard.
