Architect-owned product ecosystems—retrieval, observability, QA automation, and operational platforms—with deploy discipline enterprises and founders both expect.

About

Designing and operating software as systems: deliberate architecture, pragmatic delivery, APIs teams can reuse, and long-term maintainability over short-lived page churn.

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, editor-integrated engineering tooling with provider-independent AI integration and deterministic repository operations, 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.

Several of these products also work together. Ostuu shortens tracked links through RSI.gl. Cutfish can import SiteLens captures, and it uses TranscribeWise for transcription and narration. Valley Gate Media uses TranscribeWise too. DevFoundry exposes one capability registry through its website, CLI, MCP server, and early-preview API.

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.

  • The host page keeps its own markup. Each submission has a delivery log.
  • Built for repeatable embeds across landing pages, onboarding, ops forms.

CauseWise.io

Live

Analytics that explains what changed in site traffic by comparing events with the previous period.

Systems / stack

Postgres aggregates of site events

Open CauseWise
Operational depth
  • Each insight states the change and shows the metrics behind it, so you can check the wording against the events.
  • An insight is a plain-language account of a measured change versus the previous period, with the metrics that produced it. You can open that same insight again in CauseWise. It is computed from your events, not written by an AI model.
  • Insights are built from the events already collected for the site, compared with the previous period.
