Boring on purpose: a stack your future hires already know

We choose technologies for ten-year futures and deep talent pools — React, Next.js, Java, Spring Boot, Node.js, and proven cloud infrastructure — plus modern AI where it earns its keep.

Our stack, and why

Every technology here was chosen for a reason

We don't chase trends. We standardize on technologies with deep talent pools and long-term futures — and pick the right tool for each job rather than forcing one to do everything.

Frontend

We standardize on React and Next.js for their massive talent pools and long-term support — your product never becomes a hiring problem. Server rendering keeps things fast and search-friendly.

  • React
  • Next.js
  • Angular
  • Vue
  • TypeScript
  • Tailwind CSS

Backend

Java and Spring Boot anchor our backend work for regulated, high-reliability systems; Node.js and .NET cover the rest. We design around clean service boundaries so systems stay maintainable as they grow.

  • Java
  • Spring Boot
  • Node.js
  • .NET
  • Python
  • Microservices

Database

We pick the right store for the job — relational for integrity, document for flexibility, in-memory for speed, search for discovery — rather than forcing one database to do everything.

  • PostgreSQL
  • MySQL
  • MongoDB
  • Redis
  • Elasticsearch

Cloud

AWS, Azure, and GCP, deployed as infrastructure-as-code so environments are reproducible and auditable. We architect for scale and right-size for cost.

  • AWS
  • Azure
  • Google Cloud
  • Vercel
  • Hetzner

DevOps

Automated CI/CD, containerization, and observability make releases routine and rollbacks one click — so shipping is boring and predictable, even on complex systems.

  • Docker
  • Kubernetes
  • Jenkins
  • GitHub Actions
  • Terraform

AI & Data

We build on OpenAI and LangChain with RAG and vector databases to ground AI in your data — accurate, secure, and evaluated, not just impressive in a demo.

  • OpenAI
  • LangChain
  • AI Agents
  • RAG Systems
  • Vector DBs

How we make technology decisions

Principles that keep your software cheap to own

Boring on purpose

We choose proven technologies with ten-year futures and deep talent pools over whatever's trending — so your product is easy to hire for and cheap to maintain.

Built to scale, sized for now

Architecture that handles growth without over-engineering the first version. You don't pay for scale you don't have yet, and you don't hit a wall when you do.

Documented and testable

Code is read far more than it's written. Every system ships with automated tests and documentation good enough for any team to take over.

Secure by default

Least-privilege access, encrypted secrets, dependency scanning, and security reviews are part of the build — not a bolt-on afterthought.

How we work

A delivery process with no black boxes

Seven stages, weekly demos, and a live project board. You always know what shipped, what's next, and what it costs.

  1. Discovery

    Week 1

    We map your goals, users, and constraints into a clear problem statement and success metrics — before a line of code.

  2. Planning

    Week 2

    Scope, architecture, milestones, and a transparent estimate — signed off before development begins.

  3. Design

    Weeks 2–4

    Wireframes to high-fidelity prototypes, validated with real user flows before development.

  4. Development

    Weeks 4–12

    Sprint-based engineering with weekly demos, code review, and CI/CD from the first commit.

  5. Testing

    Continuous

    Automated, manual, performance, and security testing — release candidates, not surprises.

  6. Deployment

    Launch week

    Zero-downtime releases with rollback plans, monitoring, and launch support.

  7. Support

    Ongoing

    SLA-backed maintenance, observability, and a roadmap for what comes next.
