Full Stack Development
Expertise in building end-to-end web applications using TypeScript, React, Next.js, Remix, Nest.js, and Prisma, covering everything from data ingestion pipelines to frontend UX with high-performance retrieval and secure file management.
AI & RAG Architecture
Deep knowledge in designing and implementing Retrieval-Augmented Generation (RAG) architectures, integrating LLMs, vector databases such as Qdrant, and semantic search pipelines with query rewriting and re-ranking for production-grade AI applications.
Search & Data Engineering
Proficiency in Elasticsearch and PostgreSQL for building advanced search pipelines, managing large document corpora, and engineering automated data workflows including web-scraping and real-time PDF generation.
Python & Automation
Strong skills in Python for web-scraping, pipeline automation, and AI-powered content generation, including integration with image generation models and automated email parsing workflows.
Java & Backend Development
Experience with Java, Hibernate, and JAX-RS for backend development, including database migrations, rule-based heuristic algorithms, and integration with tools like Jira.
DevOps & Tooling
Practical experience with Git, Docker, n8n, Jira, and Figma for version control, containerization, workflow automation, project management, and UI design collaboration.
Computer Vision
Hands-on experience implementing computer vision systems using face detection with DNN, color masking, OCR text recognition, and speech recognition within autonomous robotic systems.
tRPC & API Design
Experience using tRPC and Effect-TS for type-safe API design and communication between frontend and backend in modern TypeScript-based full stack applications.
Workflow Automation with n8n
Automation of business processes such as sales pipelines using n8n, replacing manual data entry with dynamic, real-time workflows triggered by inbound client communications.
