LangLearn — The Adaptive Language Course
Adaptive language course that re-reads your level after every answer, weaving theory, exercises, spaced review, vocabulary and CEFR tests into one path that never wastes your time.
StatMed — Mortality Risk & Survival Analysis
Clinical prediction system for seriously ill hospitalized patients (SUPPORT cohort). Combines classical survival analysis (Kaplan-Meier, Cox PH) with ML baselines, focusing on calibration, fairness, and reproducibility. Served via FastAPI with an interactive risk predictor and a risk-stratified triage panel.

Master Thesis — Stable Diffusion for Vector Graphics
Developed a full AI generation system from text prompts with complete data pipeline. Fine-tuned Stable Diffusion on a custom dataset, deployed inference endpoint, and implemented AI-assisted prompt refinement with a user-friendly interface.
Movie Recommendation App
Conversational recommendation application using generative AI for personalized movie suggestions through natural language. Showcases RAG architecture and multi-source data integration.
Large-Scale Movie Reviews Analytics
Conducted large-scale data analysis on movie reviews using big data technologies. Demonstrated distributed computing and cross-platform processing.
Cloud Computing — Scalable Distributed App
Developed a distributed, scalable, elastic, and fault-tolerant application leveraging AWS cloud services. Production-grade microservices with serverless architecture and infrastructure automation.
Professional Projects
Projects I worked on professionally
the code isn't public as it contains sensitive company data.
AI-Powered Logo Generation Tool
Implemented an AI-powered tool for automated logo generation at Reply, including fine-tuning a deep learning model on a logo dataset and integrating a vectorization pipeline to convert raster images into resolution-independent SVG formats.
Skill Agent — Conversational Profiling Tool
Developed a conversational profiling tool for SDLC work at Produkto using cloud-friendly services. Built with PostgreSQL + SQLAlchemy/Alembic for multi-user support, GPT-4 via LiteLLM, delivery flow tracking, and Angular frontend.
Proposal Validation Agent
Built a full AI pipeline for automated checking of business proposals. Implemented specialized agents for rules validation, tag extraction, conflict detection, and proof-of-work using Python, FastAPI, OpenAI, LangChain, LangFuse, and RAGAS for evaluation.
Business Analyst Chatbot
Created an intelligent chatbot with a hybrid memory system combining short-term and long-term storage for smooth, context-aware conversations. Designed for business analyst workflows with persistent context across sessions.
File Processor & Parser Pipeline
Built a document classification and parsing system that handles PDF, DOCX, and PPTX files using PyMuPDF, python-docx, and Pillow. Features meaning-based document sorting with flexible GPT model selection (Vision or Text mode).
