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.

    Bringing the Just30Fit Shopify store to life has been a journey fueled by purpose, passion, and partnership. I couldn’t have done it without the incredible team at Pioneers Tech. From day one, they didn’t just offer technical support, they leaned in as true collaborators. They understood my vision to empower wellness journeys through curated, inclusive products, and they helped transform that dream into a digital reality. Together, we built more than a store. We built a platform for impact. Thank you, Pioneers Tech, for believing in the mission and showing what it means to be a true partner in innovation. Just30Fit is live, and this is only the beginning!! #Just30Fit #ShopifyLaunch #TechWithPurpose #PioneersTech #WellnessJourney #Gratitude #EcommerceEmpowerment

    Working with Zameer and his team was great - did what they said they would in a timely manner, and didn't give any pushback to changes, etc. - I can't wait for a new project to send them!
