Birnie Technology LLC
Software Engineering
Soup to Stack
Backend-first. Full-stack capable. Production integrity.
Engineering Services
Requirements gathering, architecture decisions, implementation, and infrastructure — across the full engineering stack.
Go Backend Engineering
Domain-driven microservices, REST API design, distributed systems, and bounded-context decomposition from legacy monoliths. Production-grade, observable, and built to scale.
Kubernetes & Platform
Cluster deployment, workload scaling, pod security, and self-healing infrastructure. KCNA certified with hands-on production experience at enterprise scale.
AI/ML Infrastructure
LLM orchestration services, retrieval-augmented context assembly, and inference pipeline architecture. Currently building research infrastructure at Eli Lilly.
CI/CD & DevOps
End-to-end pipeline design with GitLab CI, containerized test environments, and release automation — from commit to production with confidence.
Frontend & UX Engineering
Component-driven interfaces in React and Vue 3 — customer storefronts, admin dashboards, and internal tools. Accessible, responsive, and integrated cleanly with the backend.
Shipped Work
Portfolio
Production systems built end-to-end — architecture, implementation, and deployment.
Superior Technology
Supply chain platform rewrite — Go microservices replacing a 20-year-old ASP monolith, plus an agentless SNMP monitoring appliance
Parts Management Platform
Replaced a 300-page ASP monolith with four bounded-context Go services: standardization (part definitions and hierarchies), inventory (stock, pricing, alternates), support (product families), and an orchestration layer that aggregates across all three domains. Each service owns its MSSQL schema with versioned Goose migrations. The live legacy system (Trakker/T2Online) was bridged via read-only SQL views — enabling an incremental cutover with formal UAT/IR sign-off before ASP pages were retired.
ExpressConnect Appliance
Agentless SNMP monitoring service deployed to customer-hosted VMs (2 CPU / 4 GB). Handles 50k+ devices via a three-stage conductor pipeline — intake, match, translate — with goroutine-bounded concurrency, atomic spool operations for zero data loss, and self-healing SQL migrations that run idempotently on every startup.
Outcomes: $31M inventory moved · $7.4M surplus sales · 98% inventory accuracy
Grain & Grit
Full-stack e-commerce platform — Next.js 15 monorepo with dual apps, shared design system, and cloud-native deployment
Grain & Grit — Customer Storefront
Public-facing e-commerce store for an artisan goods business. Built on Next.js 15 with React 19, Stripe + Square payment integration, S3/R2 image storage, and rate-limited checkout flows. Deployed on Cloudflare Workers via OpenNext.
Grain & Grit — Admin Dashboard
Internal management dashboard with GitLab OAuth authentication, product and order management, customer tracking, and custom order handling. Zod-validated forms throughout. Ships in the same pnpm monorepo as the storefront.
Shared infrastructure: pnpm monorepo · Radix UI design system · Kubernetes manifests (base/dev/prod overlays) · Docker · Vitest unit tests · Playwright E2E
AI/ML infrastructure work available on request — under NDA
Track Record
Experience
4+ years shipping production systems that move real money and serve real users.
Senior Software Engineer
Ardan Labs → Eli Lilly & Co.
Built the gateway service routing research queries from Eli Lilly's internal research portal to toxicology models, ML models, and MCPs — all communicating over gRPC with a Redis cache layer on top.
Chose Go over Python for the orchestration layer to leverage goroutine-based concurrency across high-throughput inference pipelines; added Prometheus, Grafana, and Loki for observability.
Own Helm chart authoring and rollout orchestration across Dev, QA, and Prod clusters on AWS.
Software Engineer
Superior Technologies Research
Decomposed a 300-page legacy ASP supply chain monolith into 5 domain-driven Go microservices — giving Service Express the stability, standardization, and scalability to grow into the international company they are today. Result: $31M in inventory value added, $7.4M in surplus sales at 85% margin, 98% inventory accuracy.
Lead architect on the agentless SNMP trap appliance, a subscription service supporting fleets up to 50k devices (American Airlines). Constrained to 2 cores / 4 GB VMware — engineered graceful degradation and goroutine channel semantics so misbehaving vendor firmware couldn't starve legitimate trap traffic.
Contributed to AlertHub, a multi-service alert management platform (Go, Vue 3, AWS SQS/Lambda, Microsoft SQL Server) — integrated Sentry error tracking, resolved Vue component bugs, improved CI/CD pipelines.
Built PL/SQL backends for Medicaid compliance data at Spectrum Health Care, holding 100% compliance with State of Michigan regulations on sensitive healthcare data.
