I’m a Software Engineer with 8+ years of experience building scalable product systems. Currently open to freelance, contract, or remote opportunities.

My background is frontend-heavy (Angular), but over time I’ve moved into full-stack development with a strong focus on AI-integrated systems and production-grade architecture.

What I’ve built

• Product catalog platform handling millions of SKUs with fast faceted search (Typesense)
• Taxonomy and classification systems with dashboard-driven workflows
• Schema-driven UI systems that adapt to dynamic data structures
• LLM-powered assistants integrated into real product interfaces
• Workflow and automation tools built around API-driven architectures

Architecture experience

• Scalable frontend architecture using Angular and React/Next.js
• Backend services with FastAPI (modular, maintainable design)
• Search-driven systems using Typesense for low-latency filtering
• Schema-driven platforms for flexible product data modeling
• LLM integrations with validation layers (AI for intent, backend as source of truth)
• Real-time/streaming interfaces using WebSockets
• Multi-tenant design patterns for SaaS platforms

Deployment and infrastructure

• Docker-based environments for consistent builds and deployments
• CI/CD pipelines using GitLab Runner
• Cloud deployments on AWS and GCP (VMs and containerized setups)
• Reverse proxy and service orchestration for production systems
• Performance optimization for search indexing and large datasets

AI-focused work

• Building LLM-integrated applications (chat + structured workflows)
• Prompt design for consistent and reliable outputs
• Hybrid architectures combining AI with deterministic systems
• AI-assisted development workflows to accelerate delivery
• Working with large-scale datasets alongside AI interfaces

Tech stack
