Leon Rališ
7+ years building reliable, maintainable backend systems at scale. I ship clean code, optimize delivery pipelines, and use AI to multiply my output.
A bit about me
I'm a software engineer with around 7 years of experience building backend systems, internal platforms, and product features across both agency and product environments.
Most of my experience is in .NET, but I'm comfortable working across different technologies and I don't see myself as tied to a single stack. I'm language-agnostic by mindset and care more about choosing the right tool for the problem than forcing a familiar one.
I enjoy learning new technologies, solving complex problems, and building systems that are reliable, maintainable, and practical to evolve over time. My work has included invoicing, document processing, automation, internal tooling, professional certification workflows, and legacy modernization.
I also use AI tools as part of how I work, especially when exploring unfamiliar areas, speeding up execution, and extending what I can do independently. I see them as a practical way to move faster and solve problems more effectively, while still relying on engineering judgment and strong fundamentals.
What I bring to your team
Not just code, but engineering ownership, delivery velocity, and the judgment to build systems that last.
Systems at Scale
Designed and built production systems handling document processing pipelines, invoicing workflows, and real-time data ingestion across enterprise environments.
10x Delivery Speed
Reduced deployment time from 30 minutes to under 3 minutes. I don't just write features. I optimize the entire delivery pipeline to move the team faster.
Cross-Stack Versatility
Primary in .NET, production experience in Ruby on Rails and Python. I pick the right tool for the problem, not the one I'm most comfortable with.
AI-Augmented Engineering
I leverage AI tools daily to explore unfamiliar domains, accelerate development, and extend my individual impact while maintaining strong engineering judgment.
Where I've worked
Productive
Software Engineer
Contributed to backend product development within a SaaS platform, working primarily on invoicing-related functionality in a Ruby on Rails environment.
GlobalLogic
Software Engineer
Worked on backend services, integrations, and internal platforms across enterprise-focused .NET projects.
bonsai.tech
Software Engineer
Worked primarily on backend development in .NET 6, while also contributing to delivery improvements and engineering workflows.
Innovez
Software Engineer
Worked with .NET Core and WPF on desktop and backend solutions, building a strong foundation in application development and structured engineering practices.
Things I've built
Legacy COBOL Modernization Platform
Built a modular transformation tool for converting legacy COBOL-85 code into a more modern and maintainable structure.
Insurance Document Processing Platform
Worked on the core backend platform for managing scanned insurance documents and coordinating their processing across downstream systems.
Automated Invoicing Workflow
Built an invoicing capability that automatically created invoices based on budget-related rules, with the implementation structured for future scheduling support.
Professional Certification Management
Worked on a platform for managing exams, applications, and background processes related to professional certification workflows.
Energy Trading Data Pipeline
Built a Python-based pipeline for collecting, transforming, and storing publicly available market and trading data from multiple sources.
Invoice Processing & Campaign Platform
Worked on a platform that processed multiple types of invoices and supported participation flows for sweepstakes and prize campaigns.
What I work with
Backend Development
APIs, background jobs, integrations, process-heavy systems, and business-critical backend workflows.
Architecture
Maintainable system design, modular application structure, clear separation of concerns, and long-term extensibility.
Delivery
CI/CD, deployment automation, and reliability-focused engineering practices.
Technologies
Let's build something together
I'm actively looking for my next role. Whether you need a backend engineer, have a contract project, or just want to connect, I'd love to hear from you.
