Blair Xu
Sales Engineer with backend systems depth — I run technical discovery, map requirements to architecture, and deliver credible demos/POCs for API and developer products.
- Revenue ownership: Managed a $2M+ annual portfolio
- Pipeline: Generated $200K+ qualified pipeline
- Execution: Promoted SDR → AE → AM → Director
Focus areas: APIs, WebSockets, multi-tenant architecture, background jobs, observability, and pragmatic tradeoffs.
How I Work
- Technical Discovery: clarify constraints, success criteria, stakeholders, security/compliance, and integration surface area
- Solution Mapping: propose architecture, data flow, and rollout plan with risks + mitigations
- Demos / POCs: build or tailor a working demo that proves the integration path and addresses objections
- Handoffs: align implementation + engineering to accelerate time-to-value
Projects I Demo
Nodebase — Visual Workflow Automation Platform
Demo narrative: event-driven workflow execution with authenticated triggers, background jobs, and operational visibility.
- What I demo: building a workflow → triggering → observing execution
- Integration angle: webhooks + third-party API calls + AI provider nodes
- Reliability angle: retries/failures surfaced with monitoring
Stack: Next.js 15, TypeScript, tRPC, Prisma, Neon Postgres, Inngest, Sentry, Polar, Better Auth
Funroad — Multi-Tenant E-Commerce Marketplace
Demo narrative: multi-tenant storefronts + payments with Stripe Connect, including onboarding and payouts.
- What I demo: tenant storefront → purchase → digital delivery
- Payments angle: Stripe Connect onboarding + platform fees
- Security angle: tenant isolation (routing + data access)
Stack: Next.js 15, Payload CMS, Stripe Connect, MongoDB, TailwindCSS, ShadcnUI
Real-Time Sports Broadcast Engine
Demo narrative: real-time fanout delivery over WebSockets with room-based pub/sub and reconnect behavior.
- What I demo: live updates pushed to multiple clients
- Architecture angle: room-based fanout + ingestion API
- Operations angle: rate limiting + monitoring hooks
Stack: Node.js, Express, WebSockets, REST APIs, Arcjet, APM Monitoring
Sales Engineering Artifacts
Materials I use in technical evaluations: structured discovery, architecture reasoning, and proof-oriented demos.
- Discovery checklist: API + security + success criteria template
- Demo plan: 30-min technical demo outline + objection handling
- Architecture notes: Nodebase evaluation: webhooks → job execution → observability
Technical Focus
Systems & APIs: REST, WebSockets, background jobs, multi-tenant architecture, basic observability
Languages: TypeScript (primary), Go (working), Rust (deepening)
Data & Infra: PostgreSQL, MongoDB, cloud deployment, monitoring
