▪ TECH STACK
How We Build
Every technology choice at Square Post Labs is deliberate. We select tools that scale across a multi-product portfolio, minimize operational overhead, and give us full ownership of our systems.
Sovereign Infrastructure
Owned hardware, owned network, full data residency
We operate on infrastructure we physically control - redundant compute, high-density storage, and multi-path network connectivity with automatic failover. For clients in regulated industries, this means real data sovereignty, not a checkbox on a shared cloud tenant.
AI & Language Intelligence
Multi-model orchestration with full provider flexibility
Our AI layer routes across foundation models dynamically, with support for bring-your-own-key configurations and local inference. Vector search powers contextual retrieval across product data, and every model interaction is logged, monitored, and auditable. No single-vendor dependency, no data leaving systems we control.
Event Architecture
Real-time message routing across products and tenants
Our products communicate through a persistent, stream-based messaging backbone. Events flow between services with guaranteed delivery, replay capability, and tenant-level isolation. New products plug into the same bus on day one, inheriting the full integration surface without custom wiring.
Data Layer
Relational, edge-native, and object storage under one roof
Our data architecture pairs a strongly-typed relational core with edge-distributed key-value stores and scalable object storage. Data lives close to where it is consumed, queries stay fast at scale, and every byte sits on infrastructure we own and operate.
Edge Delivery
Global edge delivery with zero server management
Our products deploy to the edge - served from data centers closest to the user, with serverless compute, integrated storage, and automatic scaling. No servers to patch, no capacity to plan.
Containerization
Portable, reproducible deployments everywhere
Every service ships as an isolated container with its full dependency tree. Environments are identical from development through production, deployments are atomic and rollback-safe, and the entire stack can relocate to new infrastructure without rearchitecting.
Secrets & Configuration
Centralized, rotated, and zero-touch for clients
Every secret, token, and environment variable is managed through a single encrypted control plane. Credentials rotate automatically, access is scoped per-service, and clients never see or manage configuration. The infrastructure just works.
Workflow Automation
Multi-step pipelines that run without babysitting
We build automated workflows that chain data extraction, transformation, enrichment, and delivery across systems. Pipelines self-recover from failures, log every step, and scale from a single scheduled task to complex multi-branch orchestrations.
Engineering Discipline
Type-safe from database to browser
Full-stack type safety catches bugs before they ship and makes refactoring fearless. Every function, every API boundary, every component contract is typed and verified at build time.
Delivery Pipeline
Automated testing, review, and deployment
Every code change goes through automated checks, peer review, and continuous deployment. We ship fast because we trust the pipeline - not because we skip steps.
User Experience
Lightning-fast, zero-bloat interfaces
Our front-end architecture ships minimal JavaScript to the browser. Pages load instantly, interactive elements activate only where needed, and the experience stays snappy on any device or connection.
Design Systems
Consistent visual language at scale
We build with utility-driven styling that scales cleanly across a multi-product portfolio. Every product inherits a shared design token system - colors, typography, spacing - without fighting specificity or naming collisions.
Product Intelligence
Privacy-first analytics and experimentation
We instrument every product with analytics, feature flags, and behavioral insights - all running on infrastructure we control. No third-party data sharing, full GDPR compliance, and the flexibility to self-host when needed.
Customer Operations
Open, API-first customer data
Our CRM layer is fully open-source and API-first, giving us complete control over the customer data pipeline. No vendor lock-in, no black-box integrations - just clean data flows we own end to end.
