Fix What's Slowing You Down. Build for What's Next.

At bytecrafters, we help modernise, refactor, and rebuild legacy applications so they perform, scale, and evolve. We don’t start from scratch unless we have to — we re-engineer what works, improve what doesn’t, and create a foundation for growth. Our approach combines deep technical insight with pragmatic delivery, tailored to real-world business needs.

What We Re-Engineer

Legacy SaaS Platforms
We update ageing applications with modern architectures and frameworks — without disrupting your customers.
Slow, Fragile Codebases
We audit, refactor, and stabilise existing systems to improve performance, reliability, and testability.
Monolith to Modular
We break down tightly coupled systems and introduce clean boundaries using services, domains, or modular architecture.
Infrastructure Modernisation
We containerise, deploy to cloud platforms, and integrate monitoring — bringing operational maturity to legacy apps.

How We Work

Architecture-Driven
We start by understanding the system — its bottlenecks, risks, and opportunities — before writing a single line of code.
Preserve What Works
Not everything needs rebuilding. We keep what adds value, upgrade what doesn't, and avoid unnecessary rewrites.
Minimise Risk
We re-engineer incrementally, using clear testing, observability, and staged rollouts to avoid disruption.
