Principal framing: deeper platform seams, repeatable delivery rhythms, and integrated systems that accumulate capability thoughtfully.

  • Site: christopherhall.dev
  • Engagement: Primary enterprise engineering role + independent RazorSoft portfolio
  • Education: M.A.

Most of my career sits between application architecture and platform stewardship—enterprise workloads where resilience is mandatory, paired with RazorSoft products treated as one coherent portfolio.

Daily stacks span TypeScript/React and Node.js where integrations warrant them, disciplined .NET 8 services where that footprint already dominates, and long-running Symfony / PHP cores modernized with strangler sequencing.

Whether enterprise or RazorSoft-facing, engineering patterns stay predictable: reusable primitives, explicit APIs, Playwright-heavy browser coverage where it matters, and documentation sized for onboarding.

Current enterprise role

Durable internal platforms whose architecture teams can refactor, extend, and operate as a cohesive whole.

UniFirst Corporation

Senior full-stack engineer

Internal titles include System Applications Professional.

Breadth aligns with principal-level stewardship across interconnected UniFirst platforms and application architecture—with sustained ownership and architectural continuity.

  • Own shaping of application architectures—layering, reusable modules, integration seams, and rollout rhythms that teams inherit rather than rewriting.
  • Modernize long-running internal platforms through pragmatic Symfony adoption, reusable integrations, shared tooling, and migration strategies designed to preserve operational continuity.
  • Composable internal APIs and integrations that unwind departmental duplication, SSO-aware patterns, and operational guardrails—privileged specifics omitted deliberately.
  • Engineering hygiene: scaffolds, Playwright-aware regression rhythms, deploy checks calibrated for regulated operations and measured release cadences.
  • Partner with roadmap leaders on maintainability, observability uplift, phased refactors, and pragmatic trade-offs—respecting confidentiality.

Systems & architecture

Shapes I own end-to-end: integration seams, tenancy, retrieval pipelines, escalation-aware automation, and deploy discipline—with the maturity expected of principal ownership across enterprise and founder-led SaaS.

Application architecture

Layer boundaries for UniFirst internals and RazorSoft-backed products—contracts that survive refactors, rollout choreography, observability seams, and strangler modernization across Symfony/PHP/WordPress (and selective .NET workloads).

SaaS platforms

Tenant onboarding, seeded environments that mirror production rules, entitlement checks, rollout trains, and Stripe-backed billing paths wherever revenue rails are genuine.

APIs & integrations

Disciplined HTTP/RPC contracts, documentation with deprecation sunsets, SSO-aware flows, webhook-friendly surfaces, and shared services replacing sprawling one-off ingestion scripts.

Source-aware retrieval

Structured lookup paths, enrichment pipelines, and retrieval guardrails for source-aware systems—evaluation hooks and offline scrutiny before model-shaped features reach users.

Automation & QA

Playwright-oriented regression gates, escalation-friendly artifacts alongside CI, scripted diagnostics—repeatable scrutiny before production promotion.

Ecommerce & CMS

WordPress and Medusa-aligned surfaces orchestrating inventory, quoting, and booking workloads stitched back into Prelude-era Symfony cores—marketing velocity without sacrificing operational truth.

Developer tooling

Scaffolds and internal libraries teams actually reuse, MCP-friendly substrates when they shorten feedback loops, deploy checks calibrated for Railway/Vercel-class hosts, and documentation that survives onboarding.

Independent products & platforms

Founder-led RazorSoft portfolio: interconnected live platforms and recurring engineering discipline held to the same bar as UniFirst internals.

Independent software studio — RazorSoft

Purposefully small footprint; systems thinking dominates the roadmap. Contracts, tenancy, observability, retrieval layers, and deploy cadence matter more than isolated demos.

Postgres-aligned persistence and typed surfaces recur wherever they shorten review loops; stacks flex with concrete product constraints.

Interconnected platforms

Featured surfaces

Live stacks sharing common rigor across deterministic QA, guarded retrieval, and calibrated analytics—with integration seams where multi-tenant work demands them.

Technical defaults Typed boundaries, Postgres-shaped persistence, edge or SSR when the workload justifies it.
