Build and maintain prompt engineering strategies, chain-of-thought patterns...

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. Around 20 screens are required to be developed based on Figma designs we have already ready 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-time updates throughout the onboarding flow, and clean, maintainable TypeScript are critical. Deliverables • Complete An...

Experience with Agentic AI and LLM integration (Claude experience strongly preferred, Gemini or other models also acceptable)

I’m just getting started with IBM API Connect and would like to master the entire workflow—from writing OpenAPI YAML files right through to exposing them on a working gateway. To get there, I need a mentor who can walk me through the platform in an interactive, hands-on way rather than simply pointing me to documentation or videos. The areas I want to cover include API design and creation, securing and managing those APIs, and finally monitoring, analytics and troubleshooting once everything is live. Live screen-sharing sessions, practical lab exercises and real-world examples are the teaching methods that work best for me. Deliverables • A series of interactive remote sessions that build progressively from beginner concepts to deployment on a gateway • Step-by-st...

I need a compact micro-service written in Go that reaches out to our external hotel-inventory supplier, pulls down hotel name and location data, current room availability, and live pricing, then surfaces that information through a clean set of REST endpoints. Core behaviour • Fetch and refresh data from the supplier API on a configurable schedule, respecting their rate limits. • Expose a /search endpoint that lets callers filter results by city, hotel name, and amenities (all three must work in any combination). • Return concise JSON with the matching hotels, available rooms, and prices, ready for direct use by our front-end team. • Handle errors, time-outs, and partial failures gracefully so the API never blocks a request thread. Implementation notes Please...

I’m building a mobile platform that lets our NBFC’s direct selling agents create loan applications on the go while giving loan officers a pocket-sized console to review and approve them. The tech stack is fixed: React Native on the front end, Spring Boot micro-services with PostgreSQL 13 on the back end, all traffic funneled through Kong as the API gateway. Here’s the flow I need: an agent signs in, opens a guided form, attaches documents, and submits. The request lands in a Spring Boot service, is stored in Postgres, and appears instantly in the loan-officer view for approval or rejection. Push or in-app notifications should alert both parties at every status change, and every action must be logged for audit. I will supply wireframes, the provisional DB schema, and acc...

I need a small, well-structured REST call that receives basic product details and a U.S. delivery address, then returns the correct sales-tax code in JSON. The third-party tax provider’s documentation and keys are already available; the job is to create the wrapper endpoint (or lightweight micro-service) that talks to that provider, forwards the request parameters, parses the response, and hands my application only the tax code we need. Key points • Data handled: product details supplied in the request body or query. • Action required: fetch the appropriate U.S. tax code from the existing tax API for the given destination. No create, update, or delete operations are needed. • Response format: strictly JSON. Deliverables 1. Clean, commented source (Node.js, ...

I need a seasoned backend engineer to partner with me in shaping, building, and shipping a production-grade API service that can grow effortlessly while staying rock-solid online. AWS is my chosen cloud, so every architectural decision—from VPC layout to IAM policies—must align with best-practice patterns in that ecosystem. Scalability and reliability are the two absolutely critical pillars. The system should sustain heavy, spiky traffic without degradation and recover gracefully from failure scenarios. You’ll guide the high-level design (microservices vs. modular monolith, service-to-service communication, fault isolation) and drill down into concrete AWS components such as ALB, ECS / EKS, Lambda, DynamoDB or other NoSQL options, SQS, EventBridge, and appropriate cach...

I am looking for an experienced software engineer who actively conducts system design interviews and have experienced with payment system. PLEASE do not waste your and mine time if do not have real experience in system design. What I need: • A 60–90 minute mock system design interview session • After the interview, a walkthrough of how you were thinking as the interviewer .what you were looking for, where I lost points, and what a strong answer looks like. * Challenge my design on core areas such as idempotency, retries, high-volume transaction processing etc. related concerns • Direct feedback My current level: • 2 years of development experience • I have studied and can discuss basic system design concepts message queues, databases, caching, API gateway...

Practical experience in designing and implementing Microservices architecture, along with relevant documentation and portfolio 2. A precise, complete, transparent proposal aligned with the project re...

I’m setting up centralized authentication on our Kong API gateway and want to enable the built-in JWT plugin. The goal is straightforward: every request to our protected routes should be validated through Kong’s native JWT support, then routed onward to our existing internal microservices once the token checks out. Here’s the current state and what I need from you: • Kong is already running in our staging Kubernetes cluster, fronting several REST services. • No auth is active yet—routes are open. • I have a list of internal consumer apps that will need their own key pairs or shared secrets. • Our services already issue JWTs; payload and signing algorithm follow the standard RFC, so we only need Kong configured to recognise and verify them...
