SUMMARY

Backend-focused software engineer (B.S. Software Engineering, 2026) with hands-on experience building
production-style systems in Python: RAG/LLM pipelines, asynchronous task processing, and REST APIs with FastAPI.
Strong in PostgreSQL (incl. pgvector), Docker-based deployment, and API design. Seeking a junior backend
developer role.

EXPERIENCE

Freelance Frontend Developer | Alfa Food Trade Mar 2024 – Jun 2024
● Designed and delivered a responsive corporate website (HTML, CSS, JavaScript) from client brief to launch,
working directly with the business owner on requirements.
● Built interactive UI components (product cards, catalog sections) and ensured consistent rendering across
desktop and mobile devices.
● Optimized page load performance through asset compression, lazy loading, and layout refactoring.

PROJECTS

RAG Knowledge Assistant — FastAPI, PostgreSQL + pgvector, MCP, SSE
● Architected and built the complete backend of an intelligent knowledge-base assistant from scratch, from data
ingestion to streaming answers.
● Implemented a full RAG pipeline: semantic & contextual chunking, hybrid (BM25 + vector) search, Multi-Query
and HyDE query expansion, cross-encoder reranking, and SSE streaming with citation filtering to reduce
hallucinated references.
● Exposed the system as an MCP server over SSE and built a provider-agnostic LLM layer supporting OpenAI
and NVIDIA endpoints.
LogiGlobal — Logistics Management Platform (Team Project) | FastAPI, Celery, Redis, PostgreSQL
● Developed the backend of a route-management platform for drivers and dispatchers; owned API design, auth,
and the async processing layer.
● Integrated the OSRM routing API and offloaded route computation to Celery workers with Redis as the task
broker, keeping API responses fast under load.
● Implemented JWT authentication with access/refresh token rotation and concurrency-safe route assignment
via optimistic locking.
AgriTech Vision — Plant Disease Diagnosis System | Django, PyTorch, Docker
● Built a backend for real-time plant disease detection from leaf images, serving PyTorch model inference
through a Django REST API.
● Containerized the full stack (Django, PostgreSQL, Redis, Celery) with Docker Compose for reproducible
deployment.
● Designed a normalized PostgreSQL schema and optimized upload/inference endpoints for high-resolution
image payloads.
FlickCove — Cinema Management System (Coursework) | Django, React, MySQL
● Built an end-to-end ticket booking system: relational MySQL schema for movies, sessions and tickets, plus
RESTful endpoints for sales and real-time seat inventory.
