The Problem
Feature Development Taking Months
Our Solution
Your team is spending more time fighting the codebase than building new features. Simple changes require touching dozens of files. New developers take 6+ months to become productive.

Why Legacy Modernization Projects Fail
We've seen these problems destroy modernization initiatives. We built our approach to eliminate them.
The Problem
Skyrocketing Infrastructure Costs
Our Solution
Your on-premise data center or legacy cloud setup is eating 40% of your engineering budget. License renewals keep increasing. You're paying for capacity you don't use 90% of the time.
The Problem
Can't Hire Modern Developers
Our Solution
Junior developers don't want to work on legacy tech. Senior developers who know your stack are retiring. Recruiters laugh when you mention your tech stack. You're stuck.
"The biggest risk in modernization isn't technical—it's business disruption. We've developed an approach that keeps your systems running while we transform them underneath."— Gautam Thapa, Founder & CEO

Common Modernization Scenarios
Typical legacy challenges we solve, and the outcomes a well-run modernization targets.
Financial Services
Monolith to Microservices
Problem
15-year-old Java monolith causing 2-week deployment cycles and frequent outages.
Solution
Strangler fig migration to microservices on Kubernetes, starting with user authentication.
Target Outcome
Daily deployments, fewer outages, and lower infrastructure costs.
Insurance
Mainframe Replacement
Problem
COBOL mainframe costing $2M/year with no developers under 55.
Solution
Phased migration to cloud-native .NET Core, preserving business logic.
Target Outcome
Lower running costs, a modern tech stack, and a far larger hiring pool.
Healthcare
Data Center Exit
Problem
Physical data center lease ending with $5M infrastructure investment needed.
Solution
Full AWS migration with containerized workloads on ECS/EKS.
Target Outcome
No new hardware capex, pay-as-you-go costs, and global availability.
E-commerce
Database Modernization
Problem
Oracle database license costs growing 20% YoY, poor scalability.
Solution
Migration to PostgreSQL on RDS with read replicas and caching layer.
Target Outcome
Lower licensing costs, faster reads, and no database vendor lock-in.
Logistics
API Platform Overhaul
Problem
SOAP APIs blocking mobile app development, poor partner integration.
Solution
New REST/GraphQL gateway wrapping legacy systems, rate limiting, OAuth2.
Target Outcome
Mobile app unblocked, faster partner onboarding, higher API throughput.
SaaS
Security & Compliance Upgrade
Problem
Legacy system failing SOC 2 audit, no encryption at rest.
Solution
Implemented zero-trust architecture, secrets management, audit logging.
Target Outcome
Audit-ready controls to support SOC 2 and HIPAA assessments.

Modernization FAQ
Common questions about enterprise system modernization.
Most modernization projects take 6-18 months depending on system complexity. We use an incremental "Strangler Fig" approach, so you start seeing benefits within the first 2-3 months. Unlike big-bang rewrites that take 2+ years and often fail, our phased approach delivers value continuously while keeping your business running.
No. We design migrations to run in parallel with your existing system using the Strangler Fig pattern. We gradually route traffic to new components while keeping the old system running. Only at the very end, when we're 100% confident, do we switch over - typically with less than 1 minute of planned downtime during a maintenance window.
While modernization requires upfront investment, companies typically save 40-70% annually on infrastructure and maintenance costs. Most clients achieve ROI within 12-24 months. We provide detailed cost-benefit analysis showing exact investment requirements and break-even timeline before you commit. The specific investment depends on your system complexity, data volume, and integration requirements.
We de-risk projects through incremental delivery and our money-back guarantee. If we don't deliver measurable value in the first phase (2-4 weeks), you get a full refund. We also maintain feature parity with your legacy system and comprehensive testing, so there's no loss of functionality. Plus, we have $5M E&O insurance for additional protection.
We need ~10-20 hours/week from key stakeholders for requirements, reviews, and knowledge transfer. Your team continues their regular work - we don't require them to stop feature development. We deliberately design migrations to minimize disruption while ensuring knowledge transfer so your team can maintain the modern system afterward.
We choose technologies based on YOUR context: team skills, hiring market, operational maturity, and business requirements. We avoid resume-driven development. For example, if your team knows Java, we might recommend Spring Boot microservices rather than forcing them to learn Go. The goal is sustainable technology that your team can own long-term.
