AI-Native Principal Engineer · Product-to-Production Architect

Leif Taylor

I translate ambiguous business requirements into secure, scalable, revenue-producing systems — using agentic workflows to move from idea to production at exceptional speed.

More than a decade in production engineering, principal architecture, DevOps leadership, and AI-native delivery. I operate across product translation, full-stack implementation, infrastructure, testing, and observability. The new paradigm collapses the boundaries between those roles; this page is what one operator looks like in that paradigm.

NOWShipping the direct-to-supplier ordering platform at ConnectBase · Spearheading agentic dev workflows in production

How I work.

I work end-to-end. One operator across product translation, architecture, full-stack code, tests, infrastructure, and production — agentic workflows for speed, deep architectural judgment for trust.

Where a 2019 team spent a quarter coordinating handoffs across specialists, I ship a working system in weeks. Same correctness bar. Same operability bar. Aimed at the business outcome the brief actually asked for.

Outcomes

  1. $600K · 2 mo

    Azure spend reduction at ConnectBase. Same product, same headcount — architectural and operational discipline did the work, and the savings landed inside the first quarter.

  2. Distributed CPQ

    Re-architected ConnectBase’s telecom CPQ engine from a coordination-heavy monolith into a distributed, worker-driven quoting platform — concurrent quote computation, fault isolation, horizontal scale, and bulk pricing across complex multi-location connectivity scenarios.

  3. 0 → 1

    Direct-to-Supplier Ordering at ConnectBase. Greenfield concept to production in months — wholesalers and channel partners now purchase from thousands of suppliers in one interface.

  4. 1M+ products

    Architected the data and search layer for Chemveric’s B2B chemical marketplace — multi-source ingestion, CAS-aware catalog normalization, faceted discovery, and structured search across millions of products and thousands of supplier records.

  5. Email → RFQ

    Converted fragmented pharma procurement (emails, spreadsheets, vendor portals) into a structured RFQ workflow at Chemveric — buyer/supplier portals, RFQ lifecycle state, quote normalization, side-by-side comparison, and procurement audit trail.

  6. AI matching

    Built AI-assisted supplier-matching and R&D workflow primitives for Chemveric — semantic retrieval and capability scoring across chemistry expertise, scale, geography, timelines, and regulatory constraints, with structured RFQ intelligence on top.

  7. Multi-module IaC

    Built the Terraform / Kubernetes deployment substrate for Mobile Heartbeat’s modular cloud-native healthcare communication platform — repeatable provisioning, secrets, ingress, observability, and CI/CD across independently deployable clinical modules.

  8. AI moderation

    Architected the trust-and-safety layer for Imprint.live, an AI-driven social platform — OpenAI-powered content classification, moderation queues, policy enforcement, human-review boundaries, and audit trails across user-generated content workflows.

  9. Manual → Automated

    Took Actifio’s manual regression and feature testing into a fully automated platform — environment provisioning across a real data-center matrix: Oracle / MySQL / Postgres × RAC / single-node × 11g–18c × HP-UX / AIX / Solaris / Ubuntu / CentOS / Red Hat. Coverage and reporting baked in.

Selected architecture & delivery work.

A handful of named systems with the operational and business problems they solved. Implementation details are in the experience section below.

  • ConnectBase

    Distributed Pricing Engine

    Reengineered the monolithic pricing engine into a worker-driven microservice mesh — fault-isolated, horizontally scalable, concurrent. Work that traditionally required a small platform team.

    • Concurrent quote computation across heterogeneous supplier tariffs
    • Fault-isolated worker model — bad inputs no longer take down the engine
    • Horizontal scale-out path the legacy engine couldn’t support
    • Distributed workers
    • Pricing
    • Stateless
    • Scalability
  • ConnectBase

    Direct-to-Supplier Ordering

    Greenfield 0→1 — translated a multi-supplier purchasing problem into one unified interface. Chief developer and technical owner from spec through production.

    • 0→1 product, greenfield architecture
    • Multi-supplier order routing, normalization, and reconciliation
    • Foundation for the next generation of ConnectBase commerce flows
    • Greenfield
    • B2B Commerce
    • Multi-tenant
    • Domain modeling
  • ConnectBase

    AI-Driven Supplier Ingestion

    LLM-driven catalog ingestion and semantic retrieval that runs on its own — replaces what would have been an ongoing data-ops team.

    • 10K+ supplier products processed weekly with no human in the loop on the happy path
    • Semantic knowledge-base search across the entire ingested corpus
    • Foundation for downstream intelligence: TAM, gap analysis, recommendations
    • RAG
    • Semantic search
    • LLM workflows
    • Data ingestion
  • ConnectBase

    Cloud Cost Program

    FinOps-style discipline across Azure — $600K saved in 2 months through architectural and configuration choices, not headcount cuts or feature freezes.

    • $50K+ monthly spend reduction
    • $600K annualized savings
    • ~30% reduction in total cloud expenditure
    • Azure
    • FinOps
    • Operational discipline

    • Daily use of agentic dev workflows (Claude Code, sub-agent orchestration, MCP-style tool integration) across implementation, refactoring, and architecture iteration
    • Built and maintains the team operating patterns for AI-augmented delivery — when to delegate to an agent, where the human-in-the-loop boundary sits, how to validate generated work
