Perl Expert Development

$25/hr Starting at $400

Unlock the full potential of Perl for mission-critical web applications, automation pipelines, and system scripting with a developer who has 10+ years of hands-on expertise in CPAN modules, legacy code modernization, and performance-critical debugging. Specializing in robust, maintainable Perl solutions for finance, DevOps, and enterprise data processing.

Core Offerings:

  • Web Development: Build scalable web apps using Catalyst, Dancer, or Mojolicious with PSGI/Plack integration, REST APIs, and templating (Template Toolkit, Mason).

  • Script Optimization: Refactor legacy Perl scripts for 10x speed gains via XS/C, parallel processing (MCE), or async workflows.

  • Debugging & Maintenance: Resolve memory leaks, race conditions, and compatibility issues in Perl 5.x codebases.

  • System Automation: Craft cron jobs, log analyzers, and ETL pipelines with CPAN modules (DBI, JSON::XS, LWP).

  • Security Hardening: Patch vulnerabilities (SQLi, XSS), implement OAuth2/JWT, and encrypt data with Crypt::CBC.

  • Legacy Upgrades: Migrate Perl/CGI systems to modern frameworks (Mojolicious) with zero downtime.

Technical Expertise:

  • Performance Tuning: Profile scripts with Devel::NYTProf, optimize regex efficiency, and reduce memory footprint.

  • Database Integration: Connect to PostgreSQL, MySQL, or SQLite via DBIx::Class, Rose::DB, or raw DBI.

  • Cloud Deployment: Containerize Perl apps with Docker, deploy to AWS/GCP, and automate with Ansible.

  • Testing & CI/CD: Write unit tests (Test::More, Prove), and integrate with Jenkins/GitLab CI.

Industries Served:

  • Banking/Finance (transaction processing, risk modeling)

  • Telecom (log analysis, network monitoring)

  • Healthcare (HL7 data parsing, HIPAA-compliant scripts)

  • E-commerce (inventory sync, payment gateways)

Why Partner With Me?

  • Proven Results: Reduced script runtime by 92% for a Fortune 500 client using XS and parallelization.

  • Legacy Mastery: Upgraded 15+ Perl 5.8 systems to Perl 5.36 with backward compatibility.

  • Full-Cycle Support: Code reviews, documentation (POD), and post-deployment monitoring (Nagios integration).

  • Cost Efficiency: Slashed annual server costs by 40% for a client by optimizing Perl-based batch jobs.


Share your project requirements for a detailed technical proposal, including benchmarks and delivery timelines. Initial code assessments delivered within 48 hours.
