Full-Stack Developer | Python, FastAPI, React.js, Node.js | RAG & LLM Integration | SDE Intern / Junior Engineer

About

I am a Full-Stack and Backend Developer focused on Python (FastAPI, Django), JavaScript/TypeScript (React.js, Next.js, Node.js), and production LLM integrations. Recent Projects & Architecture: • Vextral AI (Document Q&A Platform): Built a multi-format document parser (PDF, DOCX, CSV) using FastAPI and Next.js. Integrated Gemini, Groq, and NVIDIA NIM with automatic fallback handling, using FastAPI worker threads to drop health-check latency to under 1ms. • Mandi Mitra (Agri-Tech Platform): Developed a responsive web portal for live mandi commodity rates and crop disease diagnostics. Implemented NodeCache for location-based weather data, reducing average API response times from 1.2s to <3ms with 94% diagnostic availability. • MindGuard AI (Wellness App): Built an async FastAPI backend using parallel inference (asyncio.gather) across Hugging Face transformer models (RoBERTa, GoEmotions), cutting response latency by 71% (down to <800ms). Core Technical Stack: - Languages: Python, JavaScript, TypeScript, SQL - Frontend: React.js, Next.js, Tailwind CSS - Backend & APIs: FastAPI, Node.js, Express.js, Django, REST - AI/ML: NLP, Hugging Face, Transformers, RAG, LLM, scikit-learn, Pandas, Machine Learning, LangChain - Databases & Tools: PostgreSQL, MongoDB, Qdrant, Docker, Git, Vercel Actively looking for full-time Software Development Engineer (SDE), Full-Stack, or Backend Developer roles in Bengaluru or Remote.

Work experience

Python Full Stack Intern at Ethnotech Academy, Dec 2025 - Jan 2026 · 2 mos, Bengaluru, Karnataka, India, During my internship at Ethnotech Academy, I gained hands-on experience in full-stack development and AI-powered applications. I strengthened my foundation in: Python fundamentals Django FastAPI REST APIs HTML, CSS & JavaScript SQL I also built a Vextral AI RAG-based AI API. This internship helped me develop practical skills in building end-to-end web applications and integrating AI capabilities using modern Python frameworks.

Python [AI/ML] at Dotch Endeavours Pvt Ltd, Nov 2024 - Jan 2025 · 3 mos, Mysuru, Karnataka, India, Completed an intensive internship focused on Python development and applied AI/ML fundamentals. Worked on data preprocessing, supervised learning workflows, and backend logic while contributing to real-world projects. Developed a Twitter Sentiment Analysis system using NLP techniques and machine learning algorithms, gaining practical exposure to model development and deployment concepts. Key contributions: ✦ Completed an intensive 3-month AI/ML-focused internship, applying Python to build a Twitter Sentiment Analysis system from raw data collection to model deployment — end-to-end. ✦ Developed a Twitter Sentiment Analysis pipeline using NLP (text preprocessing, tokenization, TF-IDF) and supervised classification models, achieving functional accuracy for real-time sentiment categorization. ✦ Contributed to a cross-functional development team building AI-powered backend solutions — gained practical exposure to model evaluation, data preprocessing pipelines, and integrating ML outputs into real applications. ✦ Worked within a structured Agile-style workflow, delivering weekly milestones on data preprocessing, model training, and results analysis — building professional habits in code quality and documentation.
