I build web apps end to end from API to AI agents

Arcane Library

Upload your technical documents, ask questions about them and get answers with evidence. Every claim cites the passage it came from, and when the documents don't cover a question, the app says so instead of inventing an answer.

• Full RAG pipeline: text extraction from PDF, Markdown and TXT, chunking, embeddings and vector search in pgvector
• Grounded answers from Claude with numbered citations; below a relevance floor the model is never called
• Multilingual E5 embeddings running locally, so Armenian and Russian documents work too
• Auth with password reset, bookmarks for saved answers, tests for chunking, extraction, search and chat

FinanceBot

A Telegram bot that tracks spending. Send it “4.50 coffee with milk” and it saves the entry; ask for /today or /month and it replies with a recap.

• Automatic daily digest with a link to a full web report page
• Month view: last 7 vs previous 7 days, typical day and top 3 categories
• Polling or webhook mode, command handlers wired as keyed services

AI-Powered Fleet Maintenance API

A REST API for a logistics company to manage trucks, mechanics, incidents and repair workflows. An LLM recommends the best mechanic for every incident.

• JWT auth, CRUD, pagination, search and soft deletion
• LLM via Groq API picks a mechanic with a confidence score, plus retry logic for bad output, rate limits and API failures
• Dynamic mechanic performance scoring and Cloudinary photo storage

Cashew

“Where does the money go?” An expense tracker that reads bank statement exports and turns them into a report, right in the browser.

• Spending by category, top places and a day-by-day chart
• Savings goal panel that predicts how long a target will take
• Excel statement parsing with SheetJS, light and dark themes

Lutea

An AI-focused product built at the Hack Nation AI Hackathon. Combined software engineering and AI to ship a working prototype under a tight deadline.
