A selection of products I’ve designed and built, and the problems each one solved.
Making human-rights knowledge easier to navigate with a multi-agent advisory system.
The Human Rights Advisory System uses LangGraph supervisor-worker orchestration and a retrieval pipeline over UN Human Rights documents. ChromaDB provides the knowledge store, with Python, FastAPI, and a Next.js interface connecting the experience.
Stack: Python, LangGraph, FastAPI, Next.js, ChromaDB, RAG.
A retrieval-powered chatbot that brings automotive knowledge into the conversation.
A production-ready AI chatbot platform for automotive knowledge. The pipeline combines LangGraph orchestration, hybrid search with pgvector and BM25, cross-encoder reranking, and semantic caching. The published project supports more than 100 AI models through a unified LLM interface.
Stack: Python, FastAPI, LangGraph, LangSmith, Next.js, Angular, pgvector.
An admissions and enrolment CRM for schools and universities. It tracks each prospective student from first inquiry through application, review, decision and enrolment, with duplicate detection, campaigns, events, lead scoring, an audit log and a RAG assistant for staff. Layered Go services sit behind an Angular admin portal, with PostgreSQL and a separate FastAPI RAG service.
Stack: Go, Angular, PostgreSQL, Python, FastAPI, RAG, Docker, Kubernetes.

I’ve built enterprise platforms, helped growing products mature, and improved the systems teams use to deliver software.
Download full résuméPioneered Angular applications for branch-level customer data management, cutting page load times by 60% through NgRx state management. Engineered a configurable architecture reused across five subsidiaries, reducing deployment time by 40% and maintenance effort by 30% across more than 20 developers.
Built Go document-management APIs secured with AES-256 encryption within a two-week deadline. Standardized a shared UI library that accelerated development by 30% across 10 subsidiary apps, and brought automated linting, static analysis, and TDD into code review and CI/CD.
Engineered a modular platform enabling more than 2,000 artists to manage their work, lifting user satisfaction by 70%. Designed an AWS CI/CD pipeline that reduced deployment time by 99%, and adopted Material UI to cut UI-related bug reports by 40%.
Extended the Python Flask RESTful API with HTMX pages, migrated the database to PostgreSQL with indexed queries, consolidated release notifications through AWS SNS, and ran hiring that onboarded two developers in three weeks.
Drove development of Verathread, a cross-border trade automation platform that reduced trade-related errors by 30% through automated data validation. Delivered it for the Manifest 2023 event, helping secure five potential government clients.
Built Angular micro-frontends in an Nx workspace integrating Go gRPC microservices processing 500 transactions per second, and migrated the data layer to GraphQL with Apollo Client caching for a 70% responsiveness gain.
Made an internal PrimeNG UI library Ivy-compatible and publishable, and migrated an Angular 8 application to an Nx monorepo with Angular 12.
Delivered Croatian/English translation, push notifications, and browser-based file management while maintaining a 100% on-time delivery record.
Built GG-Garage in an Nx monorepo with Angular and Go microservices to manage job cards and improve communication across departments.
Deployed the API to Kubernetes on AWS EC2 through GitOps and GitHub Actions, with the frontend hosted on AWS Amplify.
Built GG-GarageRAG, a retrieval chatbot combining LangGraph orchestration, hybrid pgvector and BM25 search, cross-encoder reranking, and semantic caching, and HRAS, a supervisor-worker multi-agent advisory system over UN human-rights documents.
I’m interested in the space between a promising idea and a system people can genuinely use.
Over the years, I’ve worked across multiple industries from logistics, e-commerce, consultancy, to Financial building enterprise software, AI products deployed in customer owned cloud infrastructure, while improving the developer experience. That includes Angular and Next.js interface, Go, Python or NodeJS services, knowledge-grounded AI systems, Kubernetes deployments, and blockchain experiments.
Whatever the technology, my priorities remain the same: understand the real problem, keep the architecture clear, deliver efficiently, and leave behind software that teams can confidently maintain.
