Spring Boot Jobs

I’m building a back-end platform in Java that relies on Spring Boot and a fully event-driven microservices architecture. Every service publishes and consumes events through our internal broker, so the code must be cleanly decoupled and highly testable. Data persistence will live in MySQL, so each service should expose its own schema and handle migrations automatically. For cloud resources I already have an AWS account configured; the main integration you’ll work with is Amazon S3 for object storage (user uploads, logs, and occasional data exports). What I need from you is a set of production-ready microservices together with the infrastructure scripts that allow me to spin up the environment quickly. Deliverables • Source code for each Spring Boot microservice, wi...

I want a lightweight Kotlin-based Android app that lets me test SMS delivery through our own workflow. The interface can stay basic and functional: a single screen for server settings and a task list, another for simple settings where I can type or paste the whitelisted numbers myself. Typical flow I have in mind • I key in the server’s IP and port. • The app calls my REST endpoint (Retrofit / OkHttp) and pulls any pending test messages. • Each task shows the destination number and the body text. • Tapping Send launches the system SMS composer with ACTION_SENDTO—no background sending at all. • When I come back, I tap Sent, Skipped, or Failed and the app pushes that status back through another REST call. Login is not strictly required, yet ...

Proof Of Concept for the mobile app for this lending platform is already live, and every middleware endpoint has been built and tested in Spring Boot. Now I need the browser-based front end. Your task is to turn my finished Figma designs into a production-grade Angular application that mirrors the mobile experience and runs flawlessly on modern browsers. As part of this POC, around 3-4 screens are required to be developed based on Figma designs we have already ready. Entire project (around 20 Screens) will be outsourced after initial due diligence You will build responsive components, hook them into our existing REST and WebSocket endpoints, implement JWT authentication (including silent refresh), and deliver a fully tested codebase. Pixel-perfect fidelity with the designs, smooth real-t...

I need an Android-based ticketing ecosystem built end-to-end for a public-transport rollout in Mumbai. The core mobile app must allow commuters to create their own user profiles, purchase or recharge tickets, and share trip activity on social channels. Real-time notifications (e.g., low balance, journey start/finish, disruption alerts) are mandatory. Behind the scenes I also need a full Automatic Fare Collection (AFC) stack: • Fare Management Engine that applies zone-based or distance-based pricing in real time. • Secure QR Server to generate and validate dynamic codes both online and offline. • Single-Sign-On so passengers can move seamlessly between mobile, web portal and station devices. • Equipment Management module covering TOM, TVM and ECU terminals—...

Our high school needs a web-based platform that unifies three core functions—maintaining detailed student records, tracking daily attendance, and managing gradebooks—so staff, students, and administrators can all work from the same, up-to-date data set. The Student Information System module should store and edit personal details, enrollment status, contact information, and any support notes faculty might need. Attendance Tracking must let teachers mark each period quickly, surface absences or tardies in real time, and generate summary reports for administrators. Gradebook Management has to handle assignment scores, weightings, final grade calculations, and produce printable or downloadable report cards. Role-based access is essential: • Teachers enter attendance and gr...
