## About

```text
At SLEEPROPE LTD, I built CarConnect’s vehicle service and maintenance module from scratch, including service history, cost calculation, filtering, and maintenance-schedule recommendations.

I integrated Gemini through Firebase Genkit in Go to extract structured data from uploaded documents, and worked on chatbots, text and image generation, and image classification using Gemini, OpenAI, and Recraft.

I co-developed vehicle-data API features, including v2 endpoints, and helped reduce response time of a legacy production service by about 30%. I also designed MongoDB schemas, ran data migrations, and optimized queries with indexes and aggregation pipelines.

I built scraping pipelines in Go and Python and worked on backend services using Redis, WebSocket, Docker, and DigitalOcean. I’m comfortable joining existing codebases and taking features from requirements to completion in collaboration with a tech lead.
