Architecture Portfolio
A showcase of system design thinking. This portfolio focuses on the underlying architecture, data flows, and structural decisions that power complex systems.
Billing & Financial Ledger System
Problem Statement
Needed a reliable system to handle recurring subscriptions, usage-based billing, payment gateway integration, and financial reconciliation.
Architecture Strategy
Event-driven billing engine with idempotent payment orchestration, distributed locking, dead-letter queues, and immutable financial ledger.
IoT Data Center Monitoring Platform
Problem Statement
Data center environments required real-time visibility into sensor telemetry, environmental metrics, and operational status across infrastructure.
Architecture Strategy
MQTT-based telemetry ingestion pipeline with time-series storage, stream processing for anomaly detection, and interactive floor plan dashboards.
AI Digital Avatar Platform
Problem Statement
Real-time generation and streaming of interactive AI avatars with sub-second latency requirements for customer-facing kiosk environments.
Architecture Strategy
WebRTC streaming gateway paired with GPU-accelerated LLM/TTS inference worker pools, SSE-based response streaming, and RTMP pipeline for avatar rendering.
RAG Enterprise Knowledge System
Problem Statement
Business teams needed instant, contextual answers from internal documents, product data, and operational knowledge without manual search.
Architecture Strategy
Retrieval-Augmented Generation pipeline with chunked vector embeddings, semantic search, and LLM response generation with source grounding.
ERP & Manufacturing System
Problem Statement
Disconnected legacy manufacturing processes caused inventory discrepancies, delayed production lines, and lack of real-time shopfloor visibility.
Architecture Strategy
Modular event-driven microservices (OMS, MES, WMS) with temporal data handling, mobile-first factory workflows, and real-time production tracking.
