ENGINEERING BLUEPRINT

Architectural Philosophy & Systems Design

How Reyaz Beigh structures mission-critical platforms: bridging theoretical algorithms with commercial resilience, real-time event webhooks, and state-of-the-art AI protocols.

PILLAR 01

Autonomous AI Agents & Model Context Protocol (MCP)

Large Language Models are limited without real-time tools and deterministic external state. Reyaz has pioneered implementations of Anthropic’s Model Context Protocol (MCP) to bridge conversational AI with enterprise APIs, catalog feeds, and live databases.

Key Architecture Pattern: Stateful JSON-RPC 2.0 servers operating over standard input/output (Stdio) and Server-Sent Events (SSE). Exposes typed tool schemas validated with Zod, enabling Claude Desktop and custom agents to safely run multi-step actions (e.g. ASIN scanning, Buy Box floor calculation, automated inbound order creation).

HYBRID RAG RETRIEVAL

Dense vector embeddings (Qdrant/Pinecone) combined with BM25 sparse keyword scoring for multi-lingual UN policy search.

CITATION GUARANTEE

Deterministic paragraph-to-timestamp matching preventing hallucinations in institutional policy environments.

AUTONOMOUS EXECUTION

Self-correcting sourcing loops that simulate competitor price curves before placing purchase orders.

PILLAR 02

High-Frequency Event Loops & Amazon SP-API

In competitive Amazon arbitrage and private label markets, prices shift in fractions of a second. Reyaz’s architecture powers Insta Repricer and Internet Mastery Community, consuming millions of daily Amazon notifications without hitting API suspension rate limits.

Key Architecture Pattern: Amazon SNS fan-out dispatches into partitioned AWS SQS queues. High-concurrency worker threads evaluate AnyOfferChanged payloads against dynamic margin matrices within < 850ms, then dispatch batched pricing feeds guarded by sliding-window Redis token bucket rate limiters.

SUB-SECOND REACTION

Achieves < 850ms from competitor price shift notification to Amazon SP-API update submission.

PROFIT FLOOR PROTECTION

Strict algorithmic safeguards preventing 'race to the bottom' price cuts, protecting $45M+ in seller inventory.

TOKEN ROTATION POOL

Seamless OAuth token refresh handling 398+ SP-API and MWS endpoints across multiple marketplace regions.

PILLAR 03

Multi-Tenant Enterprise Platforms & Physical Workflows

Whether managing complex multi-currency payroll in AvatarDesk HRMS or coordinating 3PL warehouse prep lines in Internet Mastery Community, enterprise software must guarantee absolute data isolation, zero calculation error, and seamless real-world physical integration.

Key Architecture Pattern: Onion domain-driven architecture with PostgreSQL row-level security. Implements idempotent database transactions for all financial and inventory state changes, combined with hardware barcode scanning and automated pallet manifest exports.

PILLAR 04

Edge Performance, Extensions & Cross-Platform Clients

High-scale performance demands eliminating network round-trips. In Street Poller Media (serving 1.35B+ impressions), Nuxt SSR with Cloudflare Workers guarantees sub-second LCP. In Spy Rivals X, Manifest V3 isolated Shadow DOM injection protects Amazon product page speed. In Internet Mastery Mobile, Flutter native platform channels deliver sub-120ms barcode scanning.
