Spreadsheets have hit their limit
Your business runs on spreadsheets and shared drives that crack as the team and data grow.
Web Application Development
Web Applications Built for Real Business Work
Customer portals, internal tools, dashboards, and SaaS platforms — fast, secure, scalable web applications designed around your workflows and built in Singapore.
Custom web applications, not just websites
A website tells people about your business. A web application runs it — secure logins, live data, workflows, dashboards, and transactions, all in the browser. When your operations have outgrown spreadsheets and the off-the-shelf SaaS only does 60% of what you need, a custom web app is usually the answer.
We design and build web applications around how your business actually works — customer portals, internal operations tools, reporting dashboards, and full multi-tenant SaaS platforms. It’s the same kind of software we build and run as our own products, for Singapore SMEs and the government-linked organisations we serve.
Every build is PDPA-compliant, hosted on AWS, and architected to scale and to be maintained — by us or your team — without a rewrite down the line. And because qualifying projects can be part-funded by the EDG, going custom often costs less than it first appears.
Sound familiar?
Generic SaaS doesn’t fit
You pay for software that does 60% of what you need and fight the other 40% with workarounds.
Your systems don’t talk
Data gets re-keyed between tools because nothing is actually connected.

Cloud Hosting & DevOps
Deployed and maintained on AWS with monitoring, backups, and CI/CD.
What We Build
From customer portals to full SaaS platforms
If it runs in a browser and does real work, we build it. Common projects:
Customer Portals
Self-service portals where customers book, order, pay, track, and manage their account — branded and wired to your back office.
Internal Operations Tools
Replace fragile spreadsheets and shared drives with proper tools for operations, admin, inventory, and reporting.
Dashboards & Reporting
Live dashboards that pull from your systems, so management sees the real numbers without exporting a single CSV.
SaaS & Multi-Tenant Platforms
Full products with tenants, roles, billing, and analytics — we build and run our own SaaS, so we know what it takes.
Workflow & Approval Systems
Digitise approvals, intake forms, and multi-step processes, with audit trails and automated notifications.
Legacy System Replacements
Modernise ageing software incrementally — keep what works, replace the parts that hold you back.
How We Work
How a web app gets built
- 1
Discovery & scoping
We map your current workflow and define an MVP — the smallest version that delivers real value — then give you a fixed, milestone-based quote.
- 2
UX & architecture
We design the screens and the system architecture together, so the app is intuitive to use and sound under the hood.
- 3
Agile build
We build in short iterations with working demos, so you see progress and can steer the product as it takes shape.
- 4
Integration & testing
We connect your payments, CRM, accounting, and existing systems, and test thoroughly across devices and edge cases.
- 5
Launch on AWS
We deploy on scalable AWS infrastructure with monitoring, backups, and CI/CD — and hand over clean documentation.
- 6
Support & evolution
After go-live we monitor, maintain, and iterate — most clients grow their app with us over years.

Why AppTech
Why businesses build their web apps with us
We build our own software
Automiq, BooknGo, and DispatchOps are our products — you get a team that ships and supports real software, not a project shop.
Enterprise architects
Our systems are trusted by government agencies and corporations, built by people with decades of large-scale experience.
Built to scale & maintain
Modular, documented, clean code on cloud infrastructure — extensible without a rewrite when you grow.
Singapore-based & PDPA-ready
Local accountability, same time zone, and compliance built in from day one.
EDG-fundable
Qualifying projects can be co-funded by the Enterprise Development Grant — we provide the scope and documentation you need.
Connected, not siloed
We integrate with the tools you already run, so your data flows instead of being re-keyed.
Frequently Asked Questions
What’s the difference between a website and a web application?
A website presents information; a web application does work — logins, data, workflows, dashboards, transactions. We build the second kind: software that runs in the browser and runs your operations.
What technologies do you build with?
Modern, well-supported stacks — typically React on the front end, Node.js and proven databases on the back end, hosted on AWS. We pick the stack that fits your project’s longevity and your team, not the trend of the month.
Can it integrate with our existing systems?
Yes — payments, CRM, accounting, government services, and legacy systems. Connecting tools so data flows automatically is one of the most common things we’re asked to build.
Will it scale as we grow?
It’s built to. Modular architecture, cloud infrastructure that scales with demand, and clean code that the next developer (or our team) can extend without a rewrite.
How long does a web application take to build?
A focused first version typically takes a few months; larger platforms are delivered in phases. Because we start from proven platform foundations rather than a blank page, you usually see a working version far sooner than a build-from-scratch timeline.
Who owns the code, and can the EDG help fund it?
You own the application and its source code. Qualifying custom-software projects can also be part-funded by the Enterprise Development Grant for eligible Singapore SMEs — we produce the scope and quotation your application needs.
