Expletech specializes in modernizing legacy systems, code refactoring, and migration to modern cloud architectures to eliminate technical debt.
Escape the trap of legacy code.
Stop wasting 80% of your budget on maintenance. We migrate your outdated systems to modern, fast stacks, eliminating technical debt and unlocking rapid feature delivery.
Legacy code costs too much
Outdated technology isn't just slow β it's a strategic liability that prevents you from competing in a modern market.
Legacy System
Adding even small features takes weeks because of brittle code and hidden dependencies that break everything
End-of-life frameworks and libraries are magnets for exploits that no longer receive security patches
You're paying a premium for rare developers who know old tech, while hosting costs more on non-cloud infrastructure
Top-tier engineers don't want to work on 10-year-old spaghetti code, making it impossible to build a high-performing team
Modernized System
Modular architecture allows adding new features in hours rather than weeks
Modern stacks with automated security updates and enterprise-grade protection
Optimized cloud infrastructure reduces maintenance and hosting costs by up to 65%
A modern stack (Next.js/Node.js) attracts top talent and accelerates engineering hiring
Full spectrum of modernization services
We ensure a smooth transition to modern technologies at every layer of your system.
Cloud Migration (AWS/Azure)
Moving your infrastructure to the cloud with Docker/Kubernetes containerization for automated scaling and resilience.
Refactoring & Optimization
Cleaning up the codebase, removing duplication, improving readability, and adopting TypeScript for long-term type safety.
Monolith to Microservices
Decomposing large, rigid monolithic systems into independent modules that can be developed, tested, and deployed separately.
UI/UX Modernization
Creating a fast, modern frontend built on Next.js and Tailwind, ensuring Lighthouse 95+ and instant user responsiveness.
Database Migration & Tuning
Migrating legacy, slow relational databases to modern cloud architectures with zero downtime and optimized performance.
Security & Compliance Audit
Eliminating vulnerabilities in end-of-life frameworks, upgrading libraries, and encrypting sensitive user data.
Predictable evolution
We use a 'Strangler Fig' pattern to migrate your systems piece by piece, ensuring 100% uptime throughout the transition.
Deep Audit & Discovery
We map out dependencies, identify 'rotten' code, and create a comprehensive list of all business rules hidden in the legacy system.
Bridge Architecture
Setting up the infrastructure where old and new code can coexist safely using proxies and shared databases.
Iterative Migration
We migrate modules one by one. Each new module is modern, tested, and fully functional, slowly replacing old parts.
Final Switch-Off
The legacy system is retired completely. You are now 100% on a modern stack with a team trained in the new technology.
Why you can trust us
Years of modernizing legacy systems across various industries β we resolve technical debt reliably.
Transparent pricing
Starting prices for fixed scope. Every project receives a detailed assessment after a free discovery session.
Blueprint / Audit
Deep technical audit, vulnerability check, step-by-step migration roadmap design.
MVP Migration
Migration of a single critical module (Strangler Fig pattern) to a modern stack for proof-of-concept.
Core Refactoring
Full code refactoring, TypeScript migration, database optimization, and CI/CD pipeline setup.
Enterprise Transformation
Large-scale architecture overhaul: monolith-to-microservices, cloud migration, and complete UI/UX refresh.
What determines your price
- Codebase size, age, and technical debt level
- Number of active database entities & migration complexity
- Integration coverage & test suite completeness requirements
- Strategy type (incremental Strangler Fig pattern vs. full monolith-to-microservices migration)
Your risk β removed
What is included by default in every legacy modernization project.
Fixed budget
No hidden fees. The price is locked in the contract after the Discovery phase.
Zero data loss
100% preservation of database, transactions, and client history using dual-write sync.
Zero downtime
Your users won't notice the transition. The legacy system runs in parallel with the new one.
Code guarantee
3 months of free post-launch support and full ownership transfer of the clean codebase.
