Native Swift & SwiftUI for Apple platforms
iOS and macOS applications built with Swift 6 strict concurrency, offline-first sync for the field, and on-device machine learning for features that cannot wait on a network round trip.
Software
Custom Enterprise Software & Native Applications
Stop bending your operations to fit off-the-shelf software. We engineer custom internal platforms that map perfectly to your business logic.
Overview
Off-the-shelf software forces your operations to fit its assumptions: the workflow bends, the workaround spreadsheet appears, and the licence bill grows anyway. Lexylon engineers custom internal platforms that encode your actual business logic, so the software works the way your operation does.
Users do not experience your architecture. They experience the 300 milliseconds between tap and response. We build server rendered Next.js platforms that score green on Core Web Vitals, and native applications for iOS, macOS, and Android built with the platform's own tools: Swift and SwiftUI on Apple hardware, Kotlin on Android.
Every build is engineered as a system, not a screen: typed API contracts shared between client and server, accessibility as a requirement rather than a retrofit, and observability wired in from the first deploy. The same discipline applies whether the audience is fifty warehouse operators scanning stock or five hundred thousand consumers.
Delivery works the way your organisation already does. Lexylon engineers blend into your environment, from Jira boards and Confluence pages to your Git repositories and deployment pipelines, on cloud or on-prem servers, under a security-first Agile process that follows your access rules. Behind them stands an Australian on-site engineering team with hybrid overseas capacity, and accountability that always stays in Australia. When the build ships we do not leave: maintenance and 24/7 system support keep the platform healthy for years, not sprints.
The proof
Architecture & tech stack
Sub-second Next.js portals
React Server Components by default, TypeScript with no escape hatches, and performance budgets enforced in CI rather than discovered in production.
Secure API middleware
A typed contract layer between your clients and your systems of record, shared between client and server so the two can never disagree about a field again. The services behind it are built in Java, .NET, or Python, matching whatever your team already runs.
Kotlin Android for the enterprise fleet
Rugged device and warehouse deployments in Kotlin and Jetpack Compose, engineered for scanning workflows, intermittent connectivity, and eight hour shifts.
On-device machine learning
Core ML features that run on the handset: barcode intelligence, document capture, and predictions that keep working in a network black spot.
Rescue and takeover of existing codebases
Inherited a platform nobody fully understands? We audit what exists, stabilise it, document it, and give it a future, whether we built it or not.
Embedded delivery
Your environment, our engineers, one team
Great platforms are not thrown over a fence. Lexylon works inside the systems your teams already trust, follows a security-first Agile process shaped by your rules, and stays accountable long after go-live.
Inside your tools from day one
Our engineers pick up tickets in your Jira, write pages in your Confluence, commit to your Git, and ship through your deployment pipelines, on cloud or on-prem servers. Access is granted by you and revocable by you.
Australian accountability, hybrid scale
On-site engineers in Melbourne and Sydney, extended by a hybrid overseas team when a programme needs to move faster. Ownership, decisions, and accountability never leave Australia, and clients anywhere in the world engage on exactly the same terms.
Maintenance and 24/7 system support
Launch is the midpoint, not the finish line. We maintain what we build, offer 24/7 system support for platforms that cannot stop, and the people who wrote the code are the ones who answer.
Execution methodology
01
Product and performance definition
We define what the software must do and how fast it must feel, with explicit budgets for page load, API response, throughput, and offline behaviour set before design begins. Performance is a constraint, not an aspiration.
02
Type safe, platform native build
Next.js App Router on the web, Swift 6 and Kotlin on device, and Java, .NET, or Python services behind them, with offline-first sync and message driven integration where the architecture demands it. Shared typed contracts end client and server disagreements.
03
Ship to the infrastructure that fits
Web platforms ship through Vercel CI/CD with preview deployments and Cloudflare DNS security in front. Backend systems and advanced workloads land on AWS, Azure, or your own on-prem servers, provisioned with Terraform and released with zero downtime. Real user and system metrics arrive from day one.

FAQ
Custom software questions we hear most
Can your engineers work inside our systems and processes?
Yes. We operate in your Jira, Confluence, Git, and deployment pipelines, on cloud or on-prem infrastructure, under your security protocols and sprint cadence. You control the access, and every change is reviewed and traceable.
Who owns the code you write?
You do. Work lands in your repositories from the first commit, intellectual property is assigned to you, and documentation ships with the code so no knowledge is locked inside our heads.
Do you support the software after launch?
Yes. Ongoing maintenance is part of how we engage, with 24/7 system support available for platforms your business cannot afford to pause. The same team that built it looks after it.
Is the work done in Australia?
Engineering is led on-site from Melbourne and Sydney, with a hybrid overseas team adding capacity where it helps. Accountability, architecture decisions, and your point of contact always remain Australian.
Can you take over an existing codebase?
Yes, and it is common. We audit the code and infrastructure, stabilise what is fragile, document what was never written down, and then agree a roadmap, whether the original authors are available or long gone.
Do you work with clients outside Australia?
Yes. We build and support platforms for clients worldwide, with the same engineering standards, security-first process, and 24/7 system support. Delivery is led from Australia, and the hybrid team can place capacity in your time zone where it helps.
How do you price the work?
Three models: a dedicated team reserved for your roadmap, time and materials at highly competitive hourly rates, or a fixed project or module price built from an effort estimate in hours. Whichever you choose, the cost structure is transparent from the first conversation, with no surprises after signing. Talk to us and we will recommend the model that fits.
Engagement models
Three ways to engage, one transparent cost structure
Most platform builds start project based, then settle into a dedicated team once the product becomes part of daily operations.
Dedicated team
A stable squad of Lexylon engineers reserved for your roadmap, month after month. Predictable capacity, a predictable invoice, and a team that compounds knowledge of your business.
Time and materials
Pay only for the hours worked, at some of the most competitive rates in the Australian market. Ideal when scope moves, with timesheets you can read and question line by line.
Project or module based
A fixed price built up from an honest effort estimate in hours, module by module. You see exactly how the number was reached before you sign, and it does not move unless the scope does.
