We Build Software That Ships.

A freelance software development agency. Senior engineers, direct communication, production-ready code. No fluff.

Who We Are

Senior developers who actually deliver.

We're a freelance software development agency built by senior engineers with 10+ years of experience each. No project managers in between, no outsourcing to juniors. You get direct access to the developers building your product. We've shipped SaaS platforms, mobile apps, internal tools, and APIs for startups and enterprises across fintech, healthcare, e-commerce, and logistics.

What We Do

End-to-end software development services.

01

Full-Stack Web Apps

React, Next.js, Vue, Node.js, Python, Go. Production-grade web applications from database to deployment.

02

Mobile Development

React Native and native iOS/Android. Cross-platform when it makes sense, native when it doesn't.

03

API & Backend Systems

REST, GraphQL, microservices, event-driven architecture. Backends that handle scale without falling over.

04

Cloud & DevOps

AWS, GCP, Azure. CI/CD pipelines, Docker, Kubernetes, Terraform. Infrastructure that runs itself.

05

UI/UX Design

User research, wireframes, prototypes, and design systems. Interfaces that convert and make sense to real users.

06

Technical Consulting

Architecture reviews, code audits, tech stack decisions, scaling strategy. Honest advice from people who build.
