Deep Perl Expertise
for Business-Critical Systems

Some of our team have written books on Perl. We contribute to core and build CPAN modules. That depth means we can optimize at a level most firms can't reach and give you an honest assessment of what's worth doing.

Many enterprises run on Perl systems that handle millions of transactions, manage telecommunications infrastructure, or process payments. These systems work, often brilliantly.

But they need to evolve: handle more volume, integrate with modern tools, migrate off expensive infrastructure.

We make that evolution happen without the enormous risk and cost of ground-up rewrites. We've seen too many expensive rewrite projects fail when careful modernization would have worked.

WHAT WE DO

Performance Optimization

High-volume Perl applications processing millions of transactions. Database query optimization, caching architecture, code-level optimization.

Modernization Without Rewrites

Add type safety with modern Perl practices (Moose/Moo, type systems). Improve architecture and testability. Implement async programming. All while maintaining production stability, because your business can't afford downtime. This approach works because it's lower risk, lower cost, and you see incremental value throughout instead of waiting 18 months for a big-bang deployment that might not work.

Database Migrations

Oracle to PostgreSQL migrations with Perl applications. Schema evolution, data migration, application updates. Zero-downtime transitions for business-critical systems. Lower licensing costs, easier maintenance.

CPAN Module Development

Custom module development and maintenance. Contributing to the Perl ecosystem while solving your specific problems. Because sometimes the right solution is building something that doesn't exist yet.

AI and Vector Database Integration

Yes, AI integration into Perl systems. Vector databases, LLM APIs, a provider gateway with automatic failover, and evaluation that proves a model works before you depend on it. Practical implementation that respects your existing architecture and business rules. Tools change weekly. Good process lasts. And when AI isn't the right tool, we'll tell you.

Compliance & Security

PCI and HIPAA compliance for payment and healthcare systems. Code audits, security reviews, architectural assessments. Because regulated industries have requirements that can't be compromised.

WHY CHOOSE WATAJIS FOR PERL WORK

Perl, Inside Out

We know Perl from the language itself to the CPAN modules your system depends on. So we fix problems at the source instead of working around them.

Complete Solutions

We handle the Perl backend, database migrations, DevOps and frontend integration. Your Perl system doesn't exist in isolation, and neither do our solutions.

Production-Safe Approach

We change your system in phases, test at every stage, and always keep a way back. Because hope is not a strategy.

Modern Practices Your Team Keeps

We introduce modern Perl practices that fit the architecture you already have. We explain and document every change, so your team can carry on without us.
