What we do

What our .NET modernization covers

.NET Framework to modern .NET

Projects and libraries moved to current .NET, with incompatible APIs replaced.

Web Forms and MVC to ASP.NET Core

Old web apps rebuilt on ASP.NET Core, or with a React front end where that serves users better.

WCF to modern APIs

WCF and SOAP services replaced with REST or gRPC APIs, keeping existing clients working during the move.

Cloud and containers

IIS and Windows Server hosting moved to Azure, AWS or containers on Linux.

Database modernization

SQL Server upgrades, Entity Framework updates and migration to managed cloud databases.

CI/CD and testing

Automated builds, tests and deployments so every release is safe and repeatable.

Working with us from Tokyo

How we work with Tokyo clients

Time-zone overlap

Japan is three and a half hours ahead of India, so our working days overlap for most of your afternoon, with a stand-up and same-day replies.

Japan's Act on the Protection of Personal Information (APPI)

We design to the APPI: clear purpose of use, security controls, rules for third-party and cross-border transfers, and data hosted in Japanese cloud regions when required. We sign NDAs before work starts.

Billing

Invoices in Japanese yen (JPY) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

Process

How it works

1. Free assessment

We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.

2. Plan and safety net

We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.

3. Migrate in small steps

Module by module, with both versions running side by side where needed. You see progress in a demo every week.

4. Cut over and support

A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
