Aklamio Case Study Referral Program Rule Builder

As Aklamio continued to scale their platform and expand into new markets, they faced several strategic technical challenges:

  • Legacy Architecture Constraints. Aklamio's core platform was built on a Ruby on Rails monolith that, while functional, was becoming increasingly difficult to scale and maintain as the business grew and new features were added.
  • Enterprise Client Integration. PayPal, one of Aklamio's largest clients, required a sophisticated integration to track conversions of customer referrals that came through Aklamio's hosted referral program. Similar integration was needed for eBay, another significant client.
  • Performance at Scale. With their rapid growth across Europe, certain features of Aklamio's platform were experiencing performance bottlenecks that impacted user experience as transaction volumes increased.
  • Technical Team Growth. Aklamio needed to expand their development team while maintaining cohesion and technical standards, requiring both mentorship for new team members and support in the hiring process.

effizient provided a senior product engineer who worked closely with Aklamio's team to address these challenges:

  • Monolith Modernization. Rather than pursuing a risky complete rewrite, the effizient engineer helped Aklamio begin the process of carefully extracting key services from their Ruby on Rails monolith. This approach allowed for progressive improvement while maintaining system stability and business continuity.
  • Enterprise Client Integration. The engineer built performant custom integrations for major clients including a sophisticated tracking system for PayPal's referral program that accurately attributed customer acquisitions and custom integration with eBay's systems to monitor and track the effectiveness of their referral campaigns.
  • Feature Optimization. Working collaboratively with Aklamio's team, the effizient engineer identified performance bottlenecks in critical platform features, implemented targeted optimizations to improve response times, and rearchitected data flows for better efficiency at scale.
  • Team Development. Beyond direct technical contributions, the effizient engineer provided mentorship to junior team members, participated in code reviews to maintain quality standards, supported the hiring process, and shared best practices for Ruby on Rails development at scale.

Throughout the engagement, the effizient engineer functioned as both a hands-on developer and a strategic technical advisor, helping Aklamio navigate their growth challenges while developing sustainable technical solutions.

The collaboration between effizient and Aklamio delivered significant positive impacts:

  • Architectural Improvement. The initial extraction of services from the monolith established a pattern for ongoing modernization, improving system maintainability while preserving the stability of the core platform.
  • Enterprise Client Success. The custom integration solutions for PayPal and eBay enabled accurate tracking of referral conversions, strengthening Aklamio's relationship with these key enterprise clients and demonstrating the effectiveness of their referral programs.
  • Enhanced Performance. The optimized features delivered improved response times and better handling of increased transaction volumes, supporting Aklamio's continued growth across European markets.
  • Strengthened Team. Through mentorship and knowledge sharing, the engagement helped Aklamio build a stronger internal technical team with improved practices for managing their growing codebase.

By bringing in specialized expertise from effizient at this critical growth stage, Aklamio was able to address immediate technical challenges while establishing foundations for sustained technical excellence. This strategic partnership supported Aklamio's position as a market leader in the incentive marketing space while enabling their continued expansion across European markets.

Case Study

HomeRun - Emilia App

HomeRun is a proptech startup based in Hamburg, Germany, developing Emilia – a mobile application designed to simplify property management for private homeowners. In an industry dominated by complex professional systems, HomeRun identified an opportunity to create an intuitive digital solution for individual property owners who struggle with time-consuming administrative tasks.

HomeRun Case Study Emilia App Dashboard and Statistics

HomeRun, with its strong technical team, faced the common startup challenge of delivering an ambitious minimum viable product (MVP) with limited resources:

  • Development Velocity. With a technically sophisticated product vision and approaching market launch deadlines, HomeRun needed to accelerate development of critical features for their MVP without compromising on quality.
  • Specialized Feature Development. Two complex features - document management and financial data integration - required focused attention to implement properly, drawing resources away from other critical development areas.
  • Performance Optimization. As the MVP evolved, certain database operations were showing signs of performance constraints that needed to be addressed before they could impact user experience.
  • Resource Allocation. HomeRun needed to carefully balance their strong in-house technical resources across multiple development priorities while maintaining momentum on all fronts.

HomeRun augmented their technically strong team with a single product engineer from effizient, who seamlessly integrated into their existing development workflow:

  • Strategic Resource Allocation. The effizient engineer took ownership of specific high-impact features, allowing HomeRun's core team to maintain focus on other critical development areas.
  • End-to-End Document Solution. Working alongside HomeRun's team, the effizient engineer implemented a complete document management system spanning React Native components, GraphQL API endpoints, secure cloud storage architecture, and comprehensive permission systems.
  • Financial System Integration. The engineer developed key components of the financial tracking system including integration with banking APIs for secure financial data access, reliable data ingestion pipelines, and initial classification algorithms for transaction categorization.
  • Database Performance Optimization. Leveraging specialized PostgreSQL expertise, the engineer analyzed and optimized critical database queries, implemented strategic indexing, and enhanced overall database efficiency.

The effizient engineer worked as a true extension of HomeRun's team, participating in their development processes and knowledge-sharing sessions to ensure seamless integration of the newly developed features.

The strategic augmentation of HomeRun's technical team with effizient's product engineer delivered significant benefits:

  • Accelerated Development Timeline. The additional high-level technical expertise allowed HomeRun to progress multiple development tracks simultaneously, accelerating their path to market.
  • Feature Completeness. Critical features including document management and financial data integration were fully implemented for the MVP, enhancing the product's value proposition at launch.
  • Technical Excellence Maintained. The collaboration maintained HomeRun's high standards for code quality and architectural integrity across all developed features.
  • Performance Foundation. The database optimizations ensured the application would maintain responsiveness as user data grew, preventing potential scaling issues as the user base expanded.

This targeted approach to team augmentation demonstrated the effectiveness of bringing in specialized expertise at precisely the right moment in a product's development lifecycle. By temporarily expanding their team with a single, highly skilled engineer from effizient, HomeRun was able to maintain their development momentum across all aspects of their product vision, bringing a more complete and robust MVP to market faster than would have otherwise been possible.
