Rafael Sabirzanov

Chief Technology Officer — Tech & IT Transformation — Europe

• Led the end-to-end transformation of the technology function for a ~40-person Amazon portfolio company — from five years of organic chaos to a managed, value-creating system: strategy, operating model, and roadmap.
• Cut ~$40K/year in technology costs across 35 hosting providers and the SaaS stack (full inventory, scream-tests, provider consolidation) — with zero outages.
• Built the Amazon data platform: BigQuery semantic layer over SP-API & Ads data, landed-cost COGS cascade, automated gross-margin and daily sales/PPC reporting, executive dashboards on Cloud Run; re-platformed internal analytics on ClickHouse.
• Shipped the AI layer leadership uses daily: MCP servers over live Amazon data, per-department AI "brains" (RAG with role-based access), and a consumer-intelligence panel built on a 6.1M-post corpus with 160 AI personas.
• Moved 26,000+ company files from personal accounts into governed, per-business-unit Shared Drives; migrated secrets from spreadsheets to a managed vault, enforced 2FA, revoked external shares at scale, and tied access to offboarding.
• Established the IT operating model — service-desk intake, onboarding/offboarding SOPs, and an LLM-generated internal wiki distilled from 232 source documents.

Senior Product / Tech Lead (Internal Platforms, Analytics & AI) — Office, Belgrade, Serbia

• Designed, built, and shipped 5+ internal platforms used daily across Marketing, Media Buying, Ops, and Engineering — for an Amazon portfolio doing ~$4.5M/month GMV and ~$1.2M/month ad spend.
• Built full-funnel analytics (content cost → ad spend → sales), collapsing reporting latency from ~1.5 days to hours and speeding up budget reallocation decisions.
• Shipped a content auto-launch system that cut campaign launch time from ~48h to ~6h, plus an internal task tracker adopted across teams.
• Ran AI-first delivery with Claude Code + Cursor: idea → working prototype in days, shipping from validated prototypes instead of specs.

Product & Operations Lead (Marketplace, Logistics & AI) — UAE

• Built delivery operations from scratch (hiring, playbooks, SLAs, performance management); achieved 93% on-time delivery and reduced lead time by 30% after process stabilization.
• Led engineering end-to-end (roadmap, PRDs, releases) and implemented AI-enabled customer communication and parts matching; reduced response time by 65% and improved lead-to-order conversion by 9%.
• Established sourcing workflows and optimized pricing logic; reduced "item-not-available" cancellations by 18%, improved gross margin by 2 pp, and increased quote win-rate by 8%.

Founder

• Built consumer brand from zero to $20K/month revenue; owned product specs, manufacturing, marketplace go-to-market, and unit economics. Exited via sale.
