Application modernization services

An outdated system costs more than teams often account for — in maintenance budgets, security vulnerabilities, compliance risks, and features competitors ship while yours wait in the backlog. The longer the decision is delayed, the more expensive the problem becomes.

Our application modernization services start with an honest assessment of what your system actually needs. At Brights, we protect what works, resolve what doesn't, and give you a clear path to software that supports growth rather than limits it.

Less legacy debt. More growth opportunities

Our software modernization services.

Software audit & modernization roadmap

Before any work begins, you get a full picture of where your system stands. Through application modernization consulting, we map your architecture, score your technical debt, and define the right approach for your situation. This gives you the clarity you need to make an informed decision on next steps.

Code refactoring & technical debt reduction

If your system is slowing your team down but a full migration feels premature, code refactoring is where software modernization should begin. Our application modernization agency restructures your codebase, eliminates inefficiencies, and reduces the debt that's been accumulating — leaving you with software that's faster, leaner, and easier to build on.

Cloud migration & replatforming

Moving your application to a modern cloud environment like AWS or Azure gives your infrastructure room to grow alongside your business. When providing software modernization & migration services, we ensure minimal disruption to daily operations, so you come out with elastic scaling, reduced infrastructure costs, and a setup built for where you’re heading.

Re-architecture: monolith to microservices

When a rigid system makes it hard to ship features without breaking something else in the process, re-architecture gives your team their momentum back. We break your monolith into independent, deployable services so your team can move faster, release more confidently, and scale individual components on demand.

API modernization & system integration

In a market where your ability to adopt new tools quickly defines how fast you can move, integration bottlenecks are a serious competitive liability. Our application modernization company overhauls your APIs and connects your existing system to the platforms and internal products your business depends on, without disrupting what's already working.

UI/UX audit & redesign

A slow, dated interface is the first thing your users notice — and often the last thing internal teams prioritize. As part of our custom software modernization design services, we transform your front end for speed, clarity, and usability, delivering one of the most immediately visible returns for your business stakeholders.

How we did it for our clients.

Yasno, a leading provider of electricity, gas, and energy efficiency solutions, serves over 3.5 million customers. The company needed an architecture that could handle high-traffic events like power outage announcements. We refactored the codebase, split the monolith into independent services, and implemented serverless automatic scaling. The platform now handles up to 2 million concurrent users per hour, with API performance improved tenfold.

Architecture rebuilt for 2M concurrent users

5 signs you need to update your software.

Rising operational costs

Maintenance spending grows year over year with no performance gains
Infrastructure costs scale poorly relative to actual growth
Developer time goes to workarounds, not new features

System instability

A single failure point can take the entire system down
Incidents are frequent, and root causes are hard to isolate
Your team manages risk through caution, not confidence

Delivery bottlenecks

Releases take significantly longer than they used to
Connecting to modern tools requires custom development every time
Small changes require disproportionate effort to test and ship

Security and compliance risks

Patches are difficult to apply, delayed, or inconsistently implemented
Vendor support for your core technology has ended or is ending
Meeting current compliance requirements is increasingly manual

Knowledge lock-in

Only a few people understand how the system truly works
Knowledge lives in people's heads, not in documentation
Onboarding new developers takes far longer than it should

When we'd recommend against full modernization.

"Before we scope any modernization engagement, we look for the simplest intervention that would solve the underlying problem. A system that is slow to deploy might need a CI/CD pipeline rather than a rewrite. A system with high maintenance costs might have one or two components driving most of the overhead.
Full modernization is the right call when those targeted fixes would only delay a larger, inevitable problem. But that is a conclusion we reach through comprehensive assessment."

— Dmytro Umen, Brights’ co-founder and CEO

FAQ.

In most cases, yes. When providing app modernization services, we structure work in incremental phases using blue-green releases, canary deployments, and feature flags to keep your system operational throughout. The right approach depends on your architecture and scope of changes, which is why we assess migration risk explicitly before any work begins.
