Containerizing a Machine Learning App With Flask and Docker

Added Jun 2025 3 design docs

The models that matter are the ones other people can run, and containerization is how modern teams guarantee that. This project is a focused first encounter with Docker in a machine learning context: take a working model, wrap it in a web service, and make it run identically on any machine.

The intern trains a simple scikit-learn model in Python and serves it through a small Flask application with a prediction endpoint. They then write a Dockerfile from scratch — choosing a base image, installing dependencies, copying application code, and defining the startup command — and build and run the container locally, verifying that the service responds correctly from inside its isolated environment. Clear written instructions for building and running the image round out the project, because reproducibility includes the documentation, not just the artifact.

Though deliberately small, the project delivers one of the most transferable skills in the field. The intern finishes understanding images versus containers, how dependencies get frozen into a build, and why containerized services behave consistently across machines — knowledge they will reuse in nearly every deployment task of their career.

Crop Disease Classification Service Using Transfer Learning

Crop diseases are often identified too late for effective intervention because farmers and field agronomists rarely have quick access to plant pathology expertise. A photograph of a diseased leaf contains enough signal for accurate diagnosis, but turning that signal into a dependable, scalable service is a genuine engineering challenge for agricultural research groups. The intern builds a full diagnostic platform around transfer learning: pre-trained ResNet and MobileNet backbones are fine-tuned in PyTorch on crop disease imagery, with OpenCV and NumPy handling preprocessing and a data augmentation pipeline improving robustness to lighting and orientation. A Streamlit interface lets users upload leaf photos and receive ranked disease predictions alongside explainable AI visualizations that highlight the image regions driving each classification, while a FastAPI service exposes a batch inference endpoint for research workloads and pandas powers summary reporting. The entire system is containerized with Docker so it can be deployed consistently across lab and cloud environments. The project demonstrates end-to-end applied computer vision: adapting pre-trained networks to a specialist domain, communicating model reasoning to non-technical users, and packaging research code as a deployable, reproducible service.

Lightweight Text Generation API Built With LangServe

The gap between a working LangChain script and a service other software can call is deployment, and LangServe exists to close it: it turns chains into REST APIs with typed endpoints, streaming, and an interactive playground almost for free. Knowing this path from notebook to network service is essential for any developer who wants their AI work used by anyone other than themselves, and this project walks it end to end at a friendly scale. The intern builds a FastAPI project in Python that exposes a text generation chain through LangServe. The intern first constructs the chain itself with LangChain, a prompt template feeding a language model with configurable parameters such as topic and style, then mounts it as a LangServe route, gaining automatically generated endpoints for invocation, batching, and streaming. Around this core the intern adds a health check, request logging, and clear API documentation, then exercises the service from the built-in playground and from an external client script to prove the full round trip works. The project teaches deployment fundamentals for LLM applications: how chains become HTTP services, how FastAPI and LangServe divide responsibilities, what streaming responses look like on the wire, and how to structure a small AI service so that adding the next endpoint is easy, foundations the intern will reuse in every production AI role.

Prompt Template Design and Testing Workbench for Educators

Teachers and instructional designers increasingly build AI-driven learning modules, such as quiz generators, explanation assistants, and feedback tools, and every one of them lives or dies by its prompts. Yet educators typically iterate on prompts by trial and error in a chat window, with no way to save what worked, compare variations, or enforce consistent output formats. Prompt engineering needs a workbench, the way code has an IDE. The intern builds that workbench as a Streamlit application in Python, using LangChain as the engine. The tool lets users create parameterized prompt templates with variables such as subject, difficulty, and student level; run them against OpenAI models; and compare outputs across template variations side by side. Output parsers enforce structured results, so a quiz template reliably yields well-formed questions and answers rather than loose prose, and chain sequencing lets users compose multi-step flows in which one prompt's output feeds the next, mirroring how real learning modules are assembled. The intern implements template storage, the comparison runner, and the parser configuration interface. The project demonstrates systematic prompt engineering as a discipline: template design, structured output enforcement, chain composition, and building a tool that turns an ad hoc craft into a repeatable process for a non-technical audience.
