Custom software, SaaS platforms and mobile apps for companies that have outgrown spreadsheets and off-the-shelf tools — designed, built and maintained by a small senior team.
Trusted by companies across
Three things, done properly. If your project doesn't fit one of them, we'll tell you honestly and point you somewhere better.
Internal platforms, admin systems, integrations and automations built around how your company actually works — not around what a template allows. When the off-the-shelf tool almost fits but never quite does, this is what replaces it.
Custom softwareMulti-tenant products built to be sold, not just used. Tenant isolation, billing, roles and permissions are defined in week one, not retrofitted after your second customer complains.
SaaS platformsiOS and Android applications connected to real backends, real data and real business logic. Built to ship to the stores and to survive the updates that come after.
Mobile appsThree systems companies run their operations on. Each one has its own page with the problem, what we built and what came of it.
Bilingual property platform for a coastal agency
A real estate agency on the Oaxacan coast was invisible to Google: its listings rendered in the browser, so search engines saw empty pages where the inventory should be, and half its market searches in English. We rebuilt it server-rendered and bilingual, every property indexable in both languages.

Operations platform and mobile apps for a multi-sport event
A multi-sport event moves thousands of people between venues, hotels and airports every day, and it was being run on disconnected spreadsheets and radio calls. We built one platform for the whole operation, plus the mobile apps that reach the people who never sit at a desk.

Custom ecommerce platform for medical distribution
A dental and medical supply distributor had outgrown WooCommerce, which could not express how the business actually sells. We built the platform around its real rules: approved professional pricing, lots and expiry dates, partial shipments and returns that land back in the ledger correctly.
See the caseHiring a development team usually means losing visibility for three months and hoping for the best. We work the opposite way.
We map what the system has to do, who uses it and what it connects to. You leave this stage with a written technical plan, a scope and a fixed number, whether or not you continue with us.
The person who scopes your project is the person who builds it. There are no juniors billed at senior rates and no handoffs between a sales team and a delivery team that never spoke to each other.
Let's build yoursWe use AI models across the build to move faster: scaffolding, test coverage, refactors, documentation. Every line of it is reviewed, tested and signed off by a senior developer before it reaches your repository.
The distinction matters more than the buzzword. AI without supervision produces code that works on the demo and collapses on the third change request — we know, because rescuing that code is a service we offer. Speed is worth something only if what you're left with is maintainable.
Make it real, properlyCode, repositories, infrastructure, accounts. No proprietary frameworks you can only maintain through us, no licensing traps. If you want to bring development in-house next year, everything is documented and ready to hand over.
Own what we build youTyped code, real test coverage, written documentation and a modern, widely-adopted stack. The measure of good software isn't how fast it launched — it's how cheap it is to change eighteen months later.
Build something that lastsBased in Chile, working across LATAM and North America with overlapping business hours. Meetings in Spanish or English, documentation in whichever you prefer.
Let's get startedA developer disappeared. An agency delivered something that works until you touch it. A codebase generated with AI that nobody on your team can read, extend or deploy with confidence.
We take these on. It starts with a technical audit: what's salvageable, what has to be rewritten, what it will cost and how long it will take. You get that assessment as a written document — and the honest answer, including when the honest answer is that starting over is cheaper.
Modern, widely adopted and boring in the best sense — so any competent team can pick up where we left off.
And whatever else your operation already runs on.
CeleryDev was founded in 2024 as the engineering arm of Celery Agency, and it exists to separate two businesses that kept getting confused with each other. Celery Agency does marketing, websites and online stores. CeleryDev does the heavy work: software platforms, SaaS products and mobile applications.
Behind it is Rafael Azuaje, founder and technical director — a computer engineer who spent years in UX/UI design for companies in the United States before settling in Chile in 2019. Small by design. Growing on purpose.
A defined system, a written scope, a closed number and a delivery date. Best when you know what you need built.
A reserved block of senior engineering hours each month for products that keep evolving. Best for live platforms with a roadmap.
One or more senior developers working exclusively on your product, integrated into your process and your tools. Best when you have a technical lead in-house and need capacity.
Not sure which one fits? Tell us what you're building and we'll recommend the model — including when the answer is that you don't need us yet.
Talk to usYes. Most of our work is remote, across LATAM and the United States, with overlapping business hours and meetings in Spanish or English.
You do, from day one. Code, repositories, infrastructure and accounts are yours, documented and transferable at any point.
We use it to accelerate parts of the process — scaffolding, tests, refactors, documentation. Every line is reviewed and approved by a senior developer before it's merged. We don't ship code nobody on our team fully understands.
A focused platform typically runs 8 to 12 weeks; a SaaS product with billing and multi-tenancy, 3 to 6 months. You get a real estimate after discovery, not before — anyone who quotes you a timeline in the first call is guessing.
It usually does. Changes are quoted separately with their own impact on cost and schedule, in writing, before anything gets built. No surprise invoices.
Yes, through a monthly agreement. It's optional: everything is documented so another team could take over if you'd rather.
Send us a short description of your project. You'll get a real answer from an engineer — a first read on feasibility, approach and rough range — not an automated reply and a sales sequence.
Tell us what you're building and you get a first read on feasibility, approach and rough range — from the engineer who would build it, not from a sales sequence.
