Senior Engineering Studio
Building Software That Ships
CodesSavvy is a senior engineering studio building production-ready Next.js web apps, multi-tenant SaaS platforms, mobile apps, and AI integrations for startups and businesses in the US, UK, Canada, and Australia. Fixed pricing. Weekly demos. MVPs ship in 4–8 weeks.
Our Latest Work
We have shipped web apps, AI tools, mobile platforms, and SaaS products for clients across five countries.
What We Build
We focus on a short list of services where our team has real, proven experience. We are not a generalist agency. We do web development on Next.js, multi-tenant SaaS, mobile apps, MVPs, and AI integrations — and we do them well.
Web Application Development
If your web app takes more than 2 seconds to load, half your visitors leave. We build dashboards, SaaS platforms, portals, and internal tools on Next.js and React. Clean architecture. Load times under 1 second. Built to scale from day one.
MVP Development
A real MVP is the smallest version of your product that real users can pay for. Not a prototype. We scope it down to 4-5 core features, build it properly, and ship in 4-6 weeks. Fixed price. Production-ready. No rebuilds needed.
SaaS Product Development
SaaS needs multi-tenancy, Stripe billing, role-based access, and admin dashboards from day one. Most agencies bolt these on later. We build them in from the start so you are not re-architecting at 10,000 users.
Mobile App Development
One React Native codebase. Two app stores. Half the cost of separate native apps. We handle everything: UI design, device integrations, App Store and Google Play submission.
UI/UX Design
Most design problems are not aesthetic — they are functional. Users leave because they cannot figure out what to do next. We design interfaces that are clear, fast, and built around what users are actually trying to accomplish.
Cloud Infrastructure & DevOps
Blue-green deployments. Automated rollbacks. CI/CD pipelines. Zero-downtime releases. We have taken a fintech client from 47 seconds of downtime per deploy to zero.
AI Integration
Add AI features to your existing software. OpenAI, Anthropic Claude, or Gemini integration. RAG implementation, semantic search, copilots, and document intelligence. We embed AI into product workflows that users actually use.
AI Agents for SaaS
Custom AI agents that automate real workflows inside your SaaS — customer support, internal ops, research. Function calling, tool use, multi-step reasoning. Built on the same agent patterns we ship to production.

Why Startups and Founders Choose Us
There are thousands of dev agencies. Most have the same pitch. Here is what actually makes us different.
Senior Engineers. Not a Sales Team.
The engineers who scope your project are the engineers who build it. No account managers. No junior handoffs. Every engineer has 5+ years of production experience.
Fixed Price. No Surprises.
Hourly billing is a blank check. An estimate of 200 hours becomes 400. We give you a fixed price based on a detailed written scope. If we scoped something wrong, that is on us.
You Own Everything From Day One.
Your code lives in your GitHub from the first commit. Your app deploys to your cloud accounts. Every credential is yours. Your code is never a hostage with us.
MVPs in 5 Weeks. Not 5 Months.
We scope ruthlessly. Your 20-feature wishlist becomes 4-5 features that prove your idea. Then we ship fast. Production-ready, not a prototype. The record is 3 weeks.
A Simple, Transparent Process
Most dev agencies are a black box. You sign a contract, wait months, and hope what comes out is what you asked for. That is not how we work.
Discovery Call
30 minutes. You tell us what you are building and who it is for. We ask hard questions. By the end you will know if we are the right fit — we will tell you honestly if we are not.
Written Scope & Fixed Price
Within 48 hours you get a detailed spec — every feature, every exclusion, a fixed price. No hourly billing. No scope creep. We do not write a line of code until you approve it.
Build & Weekly Demos
Every Friday you get a staging URL with working software — not a progress report. You test it, give feedback, and we adjust. Problems caught in week 2, not week 10.
Launch & Clean Handoff
We deploy, configure monitoring, document everything, and hand over every credential and repo. We do a walkthrough session. When we are done, you own everything.
