Technology Stack.

A comprehensive catalog of the technologies we use to build production-grade systems. We choose tools pragmatically: the right tool for the right job.

Frontend

Modern, performant user interfaces built for scale.

React

expert

Our core UI library for building component-driven interfaces. React's composable architecture lets us deliver complex, interactive experiences while keeping codebases maintainable across teams.

SaaS dashboardsE-commerce platformsInternal tooling portals

Next.js

expert

The production framework we pair with React for every web project. Server-side rendering, static generation, and edge middleware give us fine-grained control over performance and SEO.

Marketing sites with CMS integrationFull-stack web applicationsMulti-tenant platforms

React Native

expert

Our go-to for cross-platform mobile development. A single codebase targeting iOS and Android lets us ship native-quality mobile apps at roughly half the cost of maintaining two native teams.

Consumer mobile appsField service applicationsMobile-first fintech products

Expo

advanced

The managed toolchain we layer on top of React Native for faster iteration. Over-the-air updates and pre-built native modules dramatically shorten the feedback loop from commit to user device.

Rapid mobile prototypingMVP launches with tight timelinesApps requiring frequent OTA updates

TypeScript

expert

Every line of production code we write is TypeScript. Static typing catches entire categories of bugs at compile time and makes large codebases navigable for any engineer on the team.

Enterprise-grade applicationsShared component librariesAPI contract enforcement

Tailwind CSS

expert

Our default styling system for rapid, consistent UI development. Utility-first classes eliminate naming debates, reduce CSS bloat, and make design system tokens trivially enforceable.

Design system implementationResponsive web interfacesWhite-label theming

Backend

Server-side systems designed for reliability and throughput.

Node.js

expert

Our primary runtime for API services and real-time backends. The non-blocking event loop handles high-concurrency workloads efficiently, and sharing TypeScript across the full stack reduces context switching.

REST and GraphQL APIsReal-time websocket servicesServerless function handlers

Python

expert

The backbone of our data engineering and ML pipelines. Python's ecosystem for scientific computing and AI is unmatched, making it the natural choice when a project involves model training or data processing.

Data processing pipelinesMachine learning servicesAutomation scripts and ETL jobs

Express

expert

A minimal, battle-tested HTTP framework we reach for when we need a lightweight API layer without the overhead of a full application framework. Its middleware pattern keeps request handling composable and testable.

Microservice APIsWebhook receiversAuthentication gateways

FastAPI

advanced

Our preferred Python framework for high-performance API services. Async support and automatic OpenAPI documentation generation make it ideal for ML model serving and data-intensive endpoints.

ML model inference APIsData ingestion endpointsHigh-throughput async services

NestJS

advanced

The enterprise-grade Node.js framework we use when projects demand strict architectural patterns. Dependency injection, decorators, and modular organization bring Angular-like structure to the server side.

Enterprise backend systemsMonorepo microservice architecturesComplex domain-driven applications

Data & Databases

Data layer architecture optimized for your access patterns.

PostgreSQL

expert

Our default relational database for transactional workloads. Advanced features like JSONB columns, full-text search, and row-level security let us handle complex queries without bolting on extra services.

SaaS multi-tenant data storesFinancial transaction systemsContent management backends

MongoDB

advanced

The document database we choose when schemas are evolving rapidly or data is inherently hierarchical. Flexible document models accelerate early-stage development without sacrificing query power.

Product catalogsContent-heavy applicationsIoT event logging

Redis

advanced

Our in-memory data store for caching, session management, and real-time features. Sub-millisecond reads make it indispensable for rate limiting, leaderboards, and any hot-path data access.

Application-layer cachingSession and token storageReal-time pub/sub messaging

DynamoDB

advanced

AWS's managed NoSQL service that we deploy for workloads requiring single-digit millisecond latency at any scale. Its pay-per-request model keeps costs proportional to actual usage.

Serverless application backendsHigh-velocity event streamsUser profile and preference stores

Pinecone

proficient

A purpose-built vector database we integrate for semantic search and AI-powered retrieval. It handles the heavy lifting of nearest-neighbor lookups so our RAG pipelines stay fast and accurate.

Retrieval-augmented generationSemantic document searchRecommendation engines

Cloud & Infrastructure

Production-grade infrastructure with enterprise reliability.

AWS

expert

Our primary cloud platform for production deployments. Deep expertise across Lambda, ECS, S3, and the broader ecosystem lets us architect solutions that balance cost, performance, and operational simplicity.

Full-stack cloud deploymentsServerless architecturesMulti-region high-availability systems

GCP

advanced

Google Cloud is our choice when projects lean heavily on BigQuery analytics, Vertex AI, or tight integration with the Google ecosystem. Its networking and ML infrastructure are best-in-class.

Data analytics platformsAI/ML model training and servingKubernetes-native workloads

Azure

proficient

We deploy on Azure when clients have existing Microsoft enterprise agreements or require Azure AD integration. Its hybrid cloud capabilities serve organizations transitioning from on-prem infrastructure.

Enterprise hybrid cloud migrationsMicrosoft 365 integrated solutionsGovernment and compliance-heavy workloads

Docker

expert

Containerization is a non-negotiable part of our delivery pipeline. Docker ensures that every service runs identically from a developer's laptop through staging to production, eliminating environment drift.

Application containerizationLocal development environmentsCI/CD build pipelines

Kubernetes

advanced

The orchestration layer we use for complex, multi-service deployments. Auto-scaling, rolling updates, and self-healing give operations teams confidence in managing large distributed systems.

Microservice orchestrationAuto-scaling production workloadsMulti-service platform deployments

Terraform

advanced

Infrastructure-as-code is how we manage every cloud resource. Terraform's declarative syntax and state management let us version, review, and reproduce entire environments with a single apply.

Infrastructure provisioning and drift detectionMulti-cloud resource managementEnvironment replication for staging and QA

AI & Machine Learning

Frontier AI capabilities integrated into production systems.

OpenAI

expert

We build on OpenAI's GPT models for natural language processing, content generation, and intelligent automation. Fine-tuning and function calling let us tailor model behavior precisely to each client's domain.

Conversational AI assistantsAutomated content generationIntelligent document processing

Anthropic/Claude

expert

Claude is our preferred model for tasks demanding nuanced reasoning, long-context analysis, and safety-conscious outputs. Its extended context window makes it exceptional for code review and document synthesis.

Code analysis and generationLong-document summarizationComplex reasoning workflows

LangChain

advanced

The orchestration framework we use to build multi-step AI pipelines. Chains, agents, and retrieval components let us compose sophisticated workflows that go far beyond single-prompt interactions.

RAG pipeline orchestrationMulti-agent AI systemsTool-augmented LLM workflows

PyTorch
