Each part of this device is one practice. We design, build and run every layer, and we own how they fit together.
Security and reliability
We make your product hard to break into and hard to knock over.
Hire us to
Find and fix the riskiest gaps in your app and AWS account
Lock down sign-in, data and access before launch
Set up alarms and runbooks for when something fails
How we build it
We encrypt data with keys you control, issue file links that expire in minutes and give each service only the access it needs. We check uploads by their bytes, and add retries, timeouts and alarms.
The part: Enclosure and fasteners. What holds it together.
EnclosureEnclosure
Cloud and platform
We design, build and run your AWS foundation, so releases are routine and costs stay readable.
Hire us to
Set up AWS for a new product, with infrastructure in code
Move an existing app onto AWS one piece at a time
Make deploys routine, with approvals where they matter
Get a cloud bill you can read and predict
How we build it
We define infrastructure in code with the AWS CDK and deploy from GitHub Actions without long-lived keys. Serverless first: Lambda, Step Functions, DynamoDB and S3. Production waits for an approval.
The part: Chassis. What everything else is built on.
ChassisChassis
Back end and APIs
We build the services, APIs and billing your apps depend on.
Hire us to
Build the API your web and mobile apps share
Add sign-in, payments and subscriptions
Move slow work, like file processing, into background jobs
How we build it
We write back ends in TypeScript, on Next.js or AWS Lambda, with DynamoDB, Cognito for sign-in and Stripe for billing. Every request is checked on the server; slow work runs as background jobs.
We build web apps that load quickly, work with a keyboard and stay easy to change.
Hire us to
Launch a web product, from sign-up to billing
Rebuild a slow or dated front end
Bring your site up to WCAG 2.2 AA
How we build it
We build with Next.js, React, TypeScript and Tailwind CSS, rendered on the server or shipped as static files so pages load quickly. We test by keyboard and name every control for screen readers.
We build 3D product views, games and interactive scenes for the browser and for phones.
Hire us to
Turn a launch into a film that plays as people scroll
Show your product in 3D on your website
Build a browser game or an interactive story
How we build it
We pick the lightest 3D that does the job, from a pre-rendered film to a live scene. Films and product shots are modelled, lit and rendered in Blender from a script, so any frame can be made again.
The part: Display, showing a 3D scene. The same screen, in motion.
DisplayDisplay
Mobile apps
We build native iOS apps that share one back end with your web product.
Hire us to
Launch an iOS app
Add a native app beside your web app, on the same back end
Add sign-in, offline use and notifications to an app
How we build it
On iOS we write native SwiftUI, split into Swift packages so each feature builds and tests on its own. An iOS app calls the same API as your web app, so a business rule changes in one place.
We design the product people touch: the flows, the screens and the system that keeps them consistent.
Hire us to
Design a new product’s first version, from flows to screens
Simplify a flow people find confusing
Build a design system your developers use as code
How we build it
We design each screen around its job, using real content. Type, colour and spacing become tokens and components in code, so design and build stay in step. We check contrast, keyboard use and motion.
The part: Cover glass. The surface people meet first.
Cover glassCover glass
AI and data
We add AI that does a real job in your product, on data you control.
Hire us to
Add an AI feature that does one job well inside your product
Answer questions from your own documents and data
Review or sort what people submit, with a person in the loop
Get your data clean and in one place first
How we build it
We call hosted models, such as Anthropic’s, from your cloud account and send only the data a task needs. We check answers before users see them, log what the model did and test it on your real cases.
Convert images, PDFs and documents between formats, and keep every file private.
The approach
Files go straight from the browser to an encrypted S3 bucket by a signed link. A Step Functions workflow runs a container Lambda that does the conversion.
Today
A free guest demo at soltani.org/test: five conversions, no account.
Takes images, PDFs and Word or Pages files. Images convert to 12 formats.
Layers involved
Security and reliability, Cloud and platform and Back end and APIs
We learn what your product must do, read what already exists and agree on the scope.
You get: A written scope, the main risks and a plan for the build.
2Design
We design the flows, the screens and the architecture, and test the riskiest ideas first.
You get: Designs and an architecture you can review before we build.
3Build
We build in short cycles and show you working software as it comes together.
You get: Working software in your own repository and cloud account.
4Launch
We ship to production with alarms, logs and a way to roll back.
You get: A live product, and the notes your team needs to run it.
5Run
We keep it healthy, fix what breaks and keep improving it, or hand it over to your team.
You get: A product that keeps working, on a retainer or in your team’s hands.
Ways to work with us
Start with a discovery sprint, or go straight to a build when the scope is clear.
Discovery sprint
We study the problem with you, shape the scope and plan the build.
A fixed price, agreed up front.
You keep everything it produces, even if you stop there.
Fixed-scope build
We build and launch an agreed scope.
The scope is agreed before work starts.
The code and the cloud accounts are yours.
Ongoing retainer
We keep running and improving your product for as long as you need.
For a product we built, or one you already have.
Who you’ll work with
Silicon X is a lean team. You work directly with the people who build your product.
Will Soltani
Co-founder. Leads architecture and delivery.
Will co-founded Silicon X in 2022. On your project he plans the architecture, runs the build and supports what ships after launch. You work with him directly.
He built the serverless file converter and the scroll-film pipeline shown in our work.
