How we develop web portals

Here’s how we bring your product to life:

Discovery: Starting with solid ground

We map out how the portal should work, what it should do, and what it needs under the hood. That means aligning it with your business goals, defining detailed scope and requirements, picking the right tech stack, identifying risks (and how to mitigate them), and building a clear development plan with estimates.

Learn more

Design: Shaping the user experience

We design web portals around your goals and user roles. Every screen, flow, and interaction is built to keep the portal intuitive, scalable, and aligned with the logic we shaped during discovery.

You’ll get wireframes and a clickable prototype so that you can walk through the experience, feel how it works, and we’ll refine anything that feels off before dev begins.

Learn more

Development: Focused & flexible

We develop in sprints, using Agile to stay flexible and focused. You’ll get regular demos, updates, and full transparency into what’s done and what’s next. Our project manager tracks progress continuously to stay on course and within budget. And if priorities shift, a flexible approach helps us find the optimal way to adapt without throwing timelines or costs off track.

Testing: QA that matches your product

We don’t believe in one-size-fits-all testing. Your project will get a tailored QA strategy based on your quality expectations, product type, and risks. We define the right mix of manual and automated testing early on, so we take all necessary steps to ensure stability and performance, but without wasting time or budget on overkill.

Learn more

Deployment: Smooth release

We plan deployment early to avoid a last-minute rush or downtime. Everything’s tested, monitored, and rolled out in a way that fits your operations, whether it’s a soft launch, phased rollout, or go-live day. You’ll know exactly what’s happening and when, while we’ll make sure the release goes with minimal disruption to users and your operations.

Growth: Supporting what’s next

We’re ready to support your portal long-term: improving it with new features, updates, or whatever’s next on your roadmap.

But if you’d rather take things in-house, no problem. We have a smooth handover process to transfer all the knowledge your team needs to manage the product without any hiccups.

No-surprise web portal development

Staying on schedule

Sticking to the budget

Complete transparency

Managing risks proactively

Deadlines you can trust

We plan with both optimistic and pessimistic estimates, track SPI throughout development, and manage scope carefully. Across 100+ web projects, our delivery variance stays under 10% — so you can be confident you’ll get your portal when we said you would.

Clearing up your concerns

How do you ensure the scalability of our web solution?

We plan your portal with scalability requirements in mind: choose the right architecture, database setup, and deployment approach based on your traffic and growth plans. Whether it’s 500 users or 50,000+, we build with load balancing, stateless services, and async processing where needed.

Plus, the cloud services we usually use (AWS, Google Cloud Platform, Azure) provide autoscaling of resources, leading to less rework or manual support later — and a more reliable app, even under high load.

How do you ensure optimal web portal speed and performance?

We focus on both backend efficiency and frontend speed: optimized queries, lightweight APIs, caching, and lazy loading where it makes sense. During web portal development, we test performance under real load conditions, not just locally, to make sure your users don’t wait.

Can you integrate the new portal with our existing software?

Yes, our web portal development services cover integration with CRMs, ERPs, internal tools, and anything else that’s already part of your workflow. We start by mapping data flows and checking what’s technically possible with your existing stack (APIs, DB access, legacy formats). If APIs have some limitations, we’ll discuss them with you and find an optimal way to implement the necessary functionality.

Can you meet our quality standards?

We define quality goals early on and track them throughout the project. You’ll see demos and reports, and we’ll have regular check-ins where we align on what meets your expectations and what needs adjusting. Plus, our QA isn’t one-size-fits-all either: we tailor it to your product and business needs to keep a web portal stable and high-performing

How do you keep us in control throughout the process?

You’ll have full visibility: access to project boards, codebase, and documentation. We do regular demos, flag risks early, and never make scope or budget decisions without your sign-off. Basically, you stay informed and in control but without needing to manage every small task yourself.

How will you help us retain expertise over the parts we outsource?

Everything we build is documented and shared — code, architecture, decisions, the whole product. When we’re done, we walk your team through how it works and can run training to get them confident managing it. You’ll have the knowledge to run and scale your app without us in the room.

How can we be sure you’ll deliver exactly what’s agreed on?

We document and approve every feature before development starts, then track progress using CPI/SPI metrics and provide weekly reports to you. You’ll see regular demos and get full transparency on what’s done and what’s next. If your priorities change, we evaluate the impact together before making any changes to the scope. This approach is how our web portal development company maintained a work acceptance rate of 99.89%

Will the team be consistent so they understand our product and code?

Yes, most of our team stays for the long haul, with an average employee tenure of 3.8 years. You get people who understand your product and code. If someone does need to leave your project and a new specialist joins, our onboarding and documentation make sure they’re up to speed fast, so there’s no disruption and no lost knowledge.

Will language barriers affect communication?

Not a chance — our team speaks fluent English and works with international clients daily (98% from the US and UK). You’ll have direct access to the developers and leads, and we’ll adapt to your preferred tools and style to keep communication smooth and easy.

Will we retain full IP ownership of the product?

Yes, you own 100% of the code, architecture, and documentation. The goal of our web portal development services is to deliver a product that you’ve envisioned — once the project’s done, everything we’ve built is yours. No strings attached.

How do you handle continuity and stability, given the situation in Ukraine?

We’ve built our operations to stay resilient, no matter the circumstances. Our team works from multiple locations across Ukraine and abroad, so we’re never reliant on a single office or region. We’ve invested in strong remote infrastructure, backup power, and contingency plans to ensure uninterrupted delivery. Since 2022, our web portal development company has consistently delivered complex projects on time and signed long-term contracts with international clients, all without disruption.

How do you keep estimates accurate and our budget on track?

We rely on our experience with similar functionality to shape estimates, keeping them as realistic as possible. Throughout development, we track CPI to catch deviations early and send weekly budget reports to you. If the scope shifts, we flag the impact and get your approval first, so you won’t get unexpected invoices.
