Infopraca

Infopraca.pl is a leading Polish employment platform that connects companies with qualified professionals across diverse industries.
With a strong reputation built on trust and reliability, it has become a key player in Poland’s online recruitment landscape.

Ecler Cloud

Infopraca.pl is one of Poland’s most established job boards, serving job seekers and employers for nearly two decades. When their internal IT team was reduced to just a few members and the platform began suffering frequent downtimes, MarsBased stepped in to take full control of their digital operations, from DevOps and backend development to UX/UI and ongoing maintenance.

We rebuilt the entire platform from the ground up, migrating it from a fragmented and outdated technology stack (Python, PHP, C++) to a modern, scalable Ruby on Rails architecture. This modernization eliminated years of accumulated technical debt and positioned Infopraca.pl for long-term growth, innovation, and operational stability.

Project duration:

  • First phase: February 2021 – October 2022.

  • Ongoing development: October 2022 - Present.

Tech stack

The technologies we used in this project

Kubernetes on AWS EKS

Enhances reliability and security, optimizes cost, scalability and performance on multi-environment.

Ruby on Rails

Full-stack, server-side web application framework that enables rapid development.

Data & AI

MySQL, Redis, Elastic Search (OpenSearch) Hadoop & Spark and OpenAI integrations.

Impact

MarsBased provided a lifeline to Infopraca.pl at a critical time. With their IT operations nearly paralyzed, we took over and stabilized a platform that had been experiencing multiple shutdowns per week.

Key results achieved:

  • Full technical debt removal: Migration to Ruby on Rails unified and modernized the platform.

  • Operational stability: Eliminated downtime incidents, restoring reliability for millions of users.

  • Increased conversions: AI-powered features improved conversion rates by 10%.

  • Boosted visibility: Organic traffic rose by 25% within six months of launch.

  • Reduced costs & dependency: Streamlined infrastructure reduced internal maintenance overhead.

Challenges

Modernizing Infopraca.pl meant transforming a well-established platform while keeping its services fully operational. Together, we tackled a series of technical challenges that required both precision and innovation:

  • From legacy to modern architecture: We seamlessly migrated a diverse technology stack (Python, PHP, C++) into a unified, future-proof Ruby on Rails platform, setting the stage for faster development and long-term scalability.

  • Performance during growth: Throughout the live migration, we maintained top-tier performance and SEO visibility, even as traffic continued to increase through ongoing organic and paid campaigns.

  • Optimizing core automations: We mapped, refined, and modernized critical background jobs and automations to ensure efficiency and reliability across the platform.

  • Stability through innovation: Our team ensured uninterrupted service while upgrading the entire infrastructure and integrating new, modern technologies.

Key wins
