Household Energy Usage Tracker with Goal Setting and Insights

Added Nov 2025 3 design docs

Households and small businesses only discover their energy waste when the bill arrives, weeks after the behavior that caused it. A tracker that turns meter readings into visible trends, goals, and concrete efficiency tips shifts energy management from an annual shock to a daily habit. The intern builds the product as a mobile application backed by a full server side. In the React Native app, users log meter readings, browse usage trends across weeks and months, set consumption targets, and receive efficiency tips tied to their own patterns. A Spring Boot backend aggregates the readings, computes trend and comparison analytics, generates periodic reports, and produces the actionable insights the app surfaces, such as flagging a month tracking well above target. Core flows include reading entry with validation, goal creation and progress tracking, and report generation, all synchronized between backend and mobile client. The project exercises backend data aggregation, mobile data visualization, and the engagement mechanics that keep users returning. The intern completes it with hard evidence of full-stack mobile development skill applied to a sustainability problem with obvious real-world value.

Mobile Collaboration Platform for Dataset Annotation Teams

Every supervised machine-learning effort and many research studies depend on humans labeling data, and coordinating a distributed annotation team quickly becomes the bottleneck: who labels what, whose work gets reviewed, and how far along the dataset is. Purpose-built annotation platforms solve this, and building one exercises nearly every full-stack skill. The intern creates a mobile-first platform where teams upload datasets, split them into annotation tasks, and work through them collaboratively. A Spring Boot backend manages user roles, task assignment and distribution, submission review queues, and data integrity guarantees so that no item is labeled twice or lost. The React Native app gives annotators a fast interface for tagging and validating items, while leads monitor real-time progress, reassign work, and review submissions. Key flows include dataset upload, task claiming, annotation submission, reviewer approval or rejection, and live progress tracking across the team. The project teaches mobile development against a substantial backend, careful workflow and state modeling, and the operational realities of data quality. The intern finishes with a genuinely useful tool and demonstrable full-stack range.

Cross-Platform Project Dashboard for Research Teams

Distributed research teams juggle literature, datasets, drafts, and deadlines across email threads and scattered drives, and progress becomes invisible the moment a collaborator is in another time zone. A dedicated workspace that combines project boards, shared resources, and discussion in one place keeps multi-site research moving. The intern builds that workspace as a full-stack product. A Node.js backend with PostgreSQL manages user accounts and roles, project and milestone records, uploaded documents, and threaded discussions, and pushes real-time updates so boards stay current for everyone. A React Native mobile app gives researchers the same boards, uploads, and conversations on the go, while the web dashboard supports richer visualization of milestone progress and team activity. Core flows include creating a project board, assigning tasks, attaching documents to milestones, and tracking completion across the team. The project demands careful relational data modeling, secure file storage, role-based authorization, and synchronized state across web and mobile clients. Completing it demonstrates genuine full-stack range: backend workflow management, mobile development, and the discipline of building collaboration software people rely on daily.

Multi-Device Playlist Sync Service for Music and Podcasts

Anyone who listens to music on a phone, podcasts on a commute, and videos on a laptop knows the annoyance of playlists trapped on one device. Keeping a media library consistent everywhere is a deceptively rich engineering problem involving sync, conflicts, and shared state, which makes it an excellent full-stack training ground. The intern builds a service where users create and manage playlists of music, podcasts, and videos and access them from any device. A Node.js backend with PostgreSQL stores user libraries, playlist contents, and ordering, and implements the synchronization logic that reconciles edits made on different devices, including added items, reordering, and deletions. A React Native mobile app and a web interface both consume the same backend, so a playlist edited on the phone appears updated on the laptop moments later. Key flows include library management, playlist creation and reordering, and cross-device state refresh. The project teaches cross-platform development against a shared API, relational modeling of ordered collections, and the practical realities of synchronization, giving the intern a portfolio piece users instantly understand.
