Architectural concepts and approaches I design for elastic, scalable, multitenant applications — turning complex requirements into robust, high-throughput systems.
Scalable, elastic applications architected multitenant from the ground up — stateless services with horizontal autoscaling and strict per-merchant tenant isolation that absorb seasonal order peaks such as Black Friday and flash sales. The foundation for dispatcher solutions, shop system connectors, and ERP data-exchange strategies across the fulfillment stack.
Siloed, queue-driven processing of order, inventory, and shipment events — decoupled via message brokers with per-warehouse partitioning, backpressure, and idempotent consumers that prevent double-picks and double-shipments — delivers a well-designed throughput at maximum concurrency.
Contract-first, event-driven data exchange between shops, marketplaces, carriers, and ERP systems — real-time order and inventory sync alongside batch ETL, streaming, and change-data-capture (CDC) — with versioned schemas and guaranteed delivery that keep every sales channel consistent.
Agentic AI solutions built on LLM orchestration with tool-calling, retrieval-augmented generation (RAG), and guardrails — automating fulfillment exception handling, returns triage, and customer-service workflows end to end, with human-in-the-loop where accuracy and liability matter.
Implementation of CI/CD pipelines with Infrastructure-as-Code, automated testing, and progressive delivery (blue-green / canary, feature-flagged per merchant) for zero-downtime releases that ship safely even during peak trading hours.
An API gateway that unifies legacy WMS and ERP behind a single facade — routing, per-connector rate limiting, and centralized auth (OAuth2 / JWT) for shop, marketplace, and carrier integrations — modernizing legacy software incrementally via the strangler-fig pattern, without a full rewrite.
