Our Technology Stack

We choose our tools carefully — prioritizing reliability, performance, maintainability, and long-term support over chasing the latest trends. Here's what powers the software we build and why we chose it.

Technology Should Serve the Business

We don't pick technologies because they're trendy. We pick them because they're the best tool for your specific problem — and because we can find and train skilled developers who know them well. Exotic tech choices create maintenance headaches; proven choices create sustainable software.

Our stack is opinionated but flexible. We have deep experience with both open-source (React, Node.js, PostgreSQL) and Microsoft ecosystems (.NET, SQL Server, Azure), which means we can work with whatever infrastructure your business already has.

Frontend & Web

React

Our primary UI library for building dynamic, component-driven web interfaces with excellent developer experience and ecosystem support.

Next.js

The React framework we use for production web apps — offering server-side rendering, static generation, and the App Router for optimal SEO and performance.

TypeScript

We write TypeScript across all projects for type safety, better tooling, and code that's easier to maintain at scale.

Tailwind CSS

Utility-first CSS framework that lets us build consistent, responsive UIs quickly without leaving the component file.

Framer Motion

Animation library for polished, performant UI transitions and micro-interactions that improve perceived quality.

Mobile

React Native

Cross-platform mobile development framework we use to build iOS and Android apps from a single codebase — 90%+ code sharing with native-quality UX.

Expo

Managed React Native workflow that simplifies device API access, OTA updates, and App Store submission.

Redux

Predictable state management for complex mobile applications with many data sources and user interactions.

SQLite

On-device relational database for offline-first mobile apps that need to store and query data without connectivity.

Backend & APIs

Node.js

Our primary backend runtime — fast, event-driven, and excellent for building RESTful APIs and real-time services alongside JavaScript frontends.

.NET / C#

Microsoft's enterprise application framework for backend APIs and business logic — particularly for clients in the Microsoft ecosystem.

ASP.NET

Web framework used on legacy and enterprise projects, including multi-tenant SaaS platforms built on Microsoft infrastructure.

REST APIs

Standard HTTP APIs we build and consume across all projects — documented with OpenAPI/Swagger for clear contracts between services.

GraphQL

Used on projects where flexible querying and reduced over-fetching improves client performance and developer experience.

Databases

PostgreSQL

Our preferred open-source relational database — reliable, feature-rich, and excellent for complex queries, JSONB storage, and high-concurrency workloads.

Microsoft SQL Server

Enterprise relational database we use for clients in the Microsoft ecosystem — including MSSQL on-premises and Azure SQL in the cloud.

SQLite

Lightweight embedded database used in mobile apps and development environments for offline-first data persistence.

Redis

In-memory data store for caching, session management, and real-time pub/sub messaging in high-performance applications.

Cloud & Infrastructure

Microsoft Azure

Our primary cloud platform — we deploy on Azure Static Web Apps, Azure Container Apps, Azure SQL, and Azure Functions for scalable, managed infrastructure.

Azure DevOps

CI/CD pipelines, work item tracking, and artifact management for enterprise clients using the Microsoft development ecosystem.

GitHub Actions

Automated CI/CD workflows for building, testing, and deploying applications on every commit — reducing release risk and accelerating delivery.

Docker

Containerization for consistent development environments and production deployments — ensuring what works locally works in production.

Cloudflare

CDN, DNS management, and edge security for public-facing applications — improving performance and protecting against DDoS attacks.

Integrations & APIs

OpenAI API

GPT-4 and other language model integrations for AI-powered features including content generation, data extraction, and intelligent search.

Twilio

SMS and voice communication APIs used across multiple projects for appointment reminders, driver notifications, and volunteer coordination.

Stripe

Payment processing and subscription billing for SaaS platforms and e-commerce applications with complex pricing models.

Clerk / Firebase Auth

User authentication and identity management — handling login, registration, MFA, and social OAuth providers.

WhatsApp API

Business messaging API for applications requiring rich media communication with international users.

Resend / SendGrid

Transactional email delivery for notifications, onboarding flows, and system alerts.

The Right Tool for Your Project

Every project gets a technology recommendation based on your specific needs — not just what we're most comfortable with. During your consultation, we'll discuss:

  • Your existing infrastructure and any technical constraints
  • Your team's technical capabilities for ongoing maintenance
  • Hosting and licensing cost considerations
  • Your scalability requirements — today and 3 years from now
  • Third-party integration requirements and API compatibility
  • Security, compliance, and data sovereignty requirements
