CUSTOM SOFTWARE DEVELOPMENT

DECODE has been delivering enterprise-grade software since 2012. A few examples include:

• Security enhancement for a US telco leader: Conducted penetration testing on mobile hardware and OS to ensure enterprise-grade security.
• Carrier-grade unified communications app: Partnered for 8 years, growing our team from 5 to 17 engineers while scaling the platform.
• Mobile version of a market-leading web SDK: Delivered with a team of 10 engineering experts for a long-term client.
• Banking apps for an Italian banking group: iOS and Android apps for a client with a market value of over €30 billion.
• Railroad reservation system: Delivered complex railroad asset allocation software within 4 months and built a team of 20 engineering experts in 6 weeks.

Our track record proves we can handle scale, complexity, and long-term partnerships.

We’ve already shipped in most of the specialized areas clients ask about. Some examples:

AI. We launched a complete AI business platform for Decidr, a $50M-funded AI startup, in 5 months. We’ve also built an AI voice assistant with sub-800ms response times and an AI health platform for Supplentia, now used by 100+ practitioners.

Industrial and logistics. We built the real-time reservation system a Class I US railroad now runs on: it processes 400,000+ reservations a day and saves them over $100M.

Telecom. We scaled Metaswitch’s mobile engineering from a small team to 21 engineers delivering production software.

Regulated or sensitive data. For fintech, healthcare, and other regulated industries, we can run AI models locally on Spark, our in-house AI infrastructure, so your data never touches a public API.

If your project sits somewhere we haven’t named here, ask us directly. We’ll tell you straight if it’s a fit.

We work across the full spectrum of software development, from native mobile apps and cross-platform solutions to web applications, backend systems, and complex integrations.

We’re at our best on projects where our senior expertise can make a strategic difference.

• Enterprise collaboration: We often integrate with large in-house engineering teams to accelerate delivery and bring niche expertise. For example, we partnered with a US $12B company, joining a 200-engineer team with a small team of 10 high-quality experts, solving complex engineering challenges at scale.
• Greenfield projects: We also work with experienced founders to build products from discovery to launch. In these cases, we guide product strategy, design, and architecture while delivering high-quality, scalable code.

In short: Whether we’re strengthening an enterprise engineering team or building a product from scratch, we focus on projects where our expertise makes the biggest difference.

We look at your needs and see how they match our services. We’ll discuss:

• Project status – Where you are right now, whether it’s just an idea, a prototype, or an existing product.
• Technologies – The tech stack you’re considering or already using.
• Timeline – When you want to start and how quickly you need to start the project.
• Budget – How much you’re planning to invest in development.
• Technical feasibility – Whether the product can be built with the chosen technologies and within the timeline and budget.
  

Our best fit is usually when a client needs a full-time dedicated team for 6+ months.

And if we’re not the right fit, we’ll tell you openly.

Yes. All code and documentation belong to you from day one. No hidden clauses. No fine print.
