Senior engineers embedded in your team backed by architecture, PM, and DevOps. .NET, React, Python, Node.js. Cloud native on Azure and AWS. From SaaS platforms to enterprise systems, we ship production software, not prototypes.

Why teams bring us in

You’re 3 months in, the agency missed every deadline, and your board wants answers.
Senior engineers take 3–6 months to hire in Ireland. Your roadmap can’t wait.
Your freelancer has no architect reviewing their code and no PM managing scope.
The codebase is undocumented, untested, and the agency moved on to their next client.
You don’t need another agency pitch. You need senior engineers who ship production code with architecture oversight.

What is Custom Software Development?

Custom software development is the process of designing, building, testing, and deploying software applications tailored to a specific organisation’s business requirements, rather than using off-the-shelf commercial products. Unlike packaged software, custom solutions are built to fit exact workflows, integrate with existing systems, and scale with the business. Common examples include enterprise platforms, SaaS products, internal tools, customer portals, and API-driven applications.

Here's How We Do It

Our job is to understand your business needs, your idea, and your vision. We help you to formalize these into product requirements, which we implement with your best interests at heart.

During Discovery Phase, a team of dedicated HST Solutions experts will help you validate your product concept, define project scope and business goals, formulate precise product requirements, create a user-oriented experience and estimate the projects budget and development timeline.

Our Ul/UX experts perform user research and competition analysis, create wireframes and prototypes to bring the product vision to life. They also make sure that the future product will be user centred and easy to use.

We know how to solve your challenges by applying right technologies to your specific business environment. We dive deep into technical details and determine the right methodology fit to reach measurably higher scalability, performance and cost optimisation.

Our development team will help you reach your business goals by applying the right technologies and custom integration of different 3rd party services and APIs to your product. Key technologies we use are C-Sharp, Java, PHP, Angular, React, AWS, Microsoft Azure.

Our QA team ensures exceptional quality, security and stability of your product. So we can reduce your products’ time to market, scale business and deliver an outstanding experience to your audience.

Any custom software requires further maintenance and support services after being developed and released to the market. You can rely on HST’s specialists in covering all your technology based issues.

COMMON QUESTIONS

Frequently asked questions

HST builds custom software using .NET/C#, Python, Node.js and Java on the backend, React, Angular and Vue.js on the frontend, and React Native for mobile — all deployed cloud-native on Azure and AWS. Technology choice depends on your existing stack. Our architect recommends the best fit during discovery.

HST provides a complete delivery pod — senior engineers plus solutions architect, PM, QA, and DevOps — embedded in your team under one contract, rather than an external agency working in isolation. Your engineers join your standups, your Slack, your sprint ceremonies. The architect reviews every sprint.

A typical HST software pod (1–2 senior engineers with shared architecture, PM, QA, and DevOps) starts from €5,000–6,000 per month per engineer. Dedicated teams start from €15,000–25,000/mo. This is significantly more cost-effective than hiring individually. A senior engineer in Ireland commands €80K–€120K salary before overhead.
Yes — HST regularly takes over codebases from agencies, freelancers, and internal teams. We start with an architecture audit to assess code quality, technical debt, and deployment practices. Common scenarios include rescuing stalled projects, modernising legacy systems, and scaling codebases.
HST works with both. Clients range from funded startups (Series A–C) to enterprise organisations like Waystone managing €1.3T in assets under administration. Startups engage a managed pod (1–2 engineers). Enterprise clients need dedicated teams (3–6+). Same quality.
For managed pod engagements: 7–10 business days. For dedicated team builds: 2–4 weeks. For fixed-price projects: technical blueprint within week 1, development within 2–3 weeks. If urgent, talk to us — we’ve scaled teams within days for existing clients.
