Production software, built by senior engineers.

No offshore handoffs, no junior churn. A small team of senior engineers designs, builds, and ships full-stack web, mobile, and cloud-native systems you’ll actually want to maintain.

FULL-STACK ARCHITECTURE·0/5 LAYERS ASSEMBLED

Every layer, engineered to fit together.

From interface to infrastructure — one coherent system, assembled as you scroll.

LAYER 01

Frontend

React · TypeScript · Next.js

Renders the interface users touch — server-rendered, type-safe, fast.

LAYER 02

API Layer

REST · GraphQL · tRPC

The contract between clients and services — authenticated and rate-limited.

LAYER 03

Services

Domain logic · Queue workers

Where business rules live — orchestration, jobs, and domain logic.

LAYER 04

Database

Postgres · Redis · S3

Durable state — transactional writes, caching, and object storage.

LAYER 05

Infrastructure

Terraform · K8s · AWS

The ground it all runs on — reproducible, scaled, and observable.

What we do

Software built to be owned, not just shipped.

We design and build full-stack web, mobile, and cloud-native applications with a small team of senior engineers. No offshore handoffs, no rotating juniors — the people who scope your project are the ones who write the code.

Every engagement ships working software on a short cycle, with tests, observability, and documentation built in. You get a system your own team can extend and maintain long after we’re gone.

What we deliver

From greenfield builds to legacy rescue.

Full-stack web applications

Typed, tested web apps with clean APIs and a front end your team can extend.

React · TypeScript · Node

Mobile applications

Native and cross-platform apps with CI, crash reporting, and store delivery handled.

iOS · Android · React Native

APIs & integrations

Versioned REST and GraphQL APIs, plus resilient integrations with third-party systems.

REST · GraphQL · Webhooks

Cloud-native architecture

Containerized services designed for horizontal scale, with infrastructure defined as code.

Docker · K8s · Terraform

Legacy modernization

Incremental migration off brittle codebases — strangler-fig, not risky big-bang rewrites.

Refactor · Migrate · Strangler

QA & automated testing

Unit, integration, and end-to-end suites wired into CI so releases stop being scary.

Problems we solve

Signs it’s time to bring us in.

“The MVP works but won’t scale.”

We re-architect the parts that matter — data model, services, deploys — without a from-scratch rewrite.

“Every release is a fire drill.”

We add CI, automated tests, and safe deploy pipelines so shipping becomes routine.

“No one wants to touch the codebase.”

We pay down the riskiest debt, add test coverage, and document the paths your team fears.

“Integrations break and customers tell you first.”

We build resilient, observable integrations with retries, monitoring, and alerting.

How we engage

A clear path from scope to a maintainable system.

Scope & architecture

We define the system, data model, and interfaces before writing code.

Iterative delivery

We ship working software every two weeks with demos, not status decks.

Hardening & tests

We add coverage, observability, and performance work before launch.

Handoff & docs

We document the system and hand it to a team that can own it.

Example engagements

Recent work, lightly anonymized.

Marketplace

Monolith to services

Decomposed a strained Rails monolith into typed services with CI and observability — deploys went from weekly to on-demand.

Healthtech

Mobile app in 14 weeks

Designed, built, and shipped a HIPAA-aware React Native app to both stores in a single quarter.

Logistics

Legacy PHP modernized

Migrated a brittle PHP system to typed Go and React, with a test suite that made changes safe again.

Why Avago

Senior engineers who stay accountable to what they ship.

A practitioner, not a slide deck

The person who scopes your work is the person who does it. No bait-and-switch staffing, no juniors learning on your time.

Senior by default

Every engagement is led by an engineer who has run production systems for 15+ years — across software, infrastructure, and operations.

We leave you self-sufficient

We document, train your team, and hand off cleanly. Success is measured by how little you need us afterward.
