AI Prototype to Production • Software Architecture • Distributed Systems

Haris Agic

I solve difficult production engineering problems.

From distributed systems and cloud platforms to AI-enabled products, I help companies design, build, and harden software that needs to perform reliably in the real world.

Hands-on across TypeScript, Node.js, React, .NET, AWS, Kafka, Docker, Kubernetes, SQL, GraphQL, REST APIs, and modern integration architecture.

Based in Vienna, working with clients across Europe and worldwide remote teams.

Available for software contractor and consulting engagements across Austria, the DACH region, Europe, and worldwide.

Professional Summary

I work at the point where engineering complexity meets production responsibility. With 20 years of experience, I help companies scale distributed systems, modernize platforms, improve reliability, and move promising AI prototypes toward production-ready systems. I contribute directly in code, while bringing the technical judgment needed for real production environments.

How I Help

AI Prototype to Production

I help teams move AI work beyond the prototype stage by designing the surrounding production architecture: integration workflows, observability, reliability, security, and operational delivery.

Distributed Systems and Integrations

I design and deliver services, APIs, and event-driven workflows that need to perform reliably across multiple systems, teams, and business-critical processes.

Platform Modernization

I help modernize legacy applications, delivery pipelines, and platform architecture without losing sight of continuity, maintainability, or long-term system health.

Reliability and Scale

I improve performance, resilience, and production readiness for systems operating under real traffic, uptime expectations, and operational pressure.

Hands-On Technical Leadership

I work directly in implementation while helping shape architecture, technical direction, cross-team delivery, and difficult engineering decisions.

Technical Skillset

Frontend: React, Next.js, Angular, TypeScript, JavaScript, HTML5, CSS3, Bootstrap, MUI.

Backend: Node.js, Express.js, .NET, .NET Core, C#, REST APIs, GraphQL, OpenAPI, Swagger, microservices, and event-driven architecture.

Data, cloud, and platform: SQL, PostgreSQL, MongoDB, AWS, Kafka, Docker, Kubernetes, Elasticsearch, GitHub Actions, and GitLab CI/CD.

Testing and delivery: Cypress, production hardening, integration workflows, observability, and reliable delivery practices.

AI Systems in Production

Many teams can prototype with AI. Far fewer can move that work toward production successfully. I help bridge that gap by building the systems around the model: architecture, integration, observability, reliability, security, cost awareness, and production delivery.

The challenge is rarely just connecting to a model API. The real work is making AI useful inside production software, business workflows, and existing platforms in a way that can be supported, measured, and improved over time.

Selected Engagements

Selected work across operational platforms, distributed systems, real-time products, and production-facing software delivery.
