I’m building and maintaining a series of backend services and I need an experienced Python developer who feels at home in FastAPI. The day-to-day work centres on designing clean, scalable REST endpoints, wiring them to a PostgreSQL database, and keeping the Dockerised environment tidy for smooth deployments. Most of the upcoming tasks involve integrating external providers: think payment gateways for transaction flow and AI/ML services that power in-app intelligence. Beyond those, you’ll help craft automation scripts, refine existing business logic, and keep an eye on performance as traffic grows. Here is what a typical assignment looks like: • create or extend a FastAPI micro-service • expose secure endpoints, including user auth where required • conne...

This project centres on replacing a monolithic, legacy insurance platform with a clean, high-performance .NET Core API designed around Domain-Driven Design. The first bounded contexts to rebuild are User Authentication & Authorization and Policy Management; Claims Processing may follow once the new foundation proves stable. The current system struggles with sluggish response times, can’t scale when new brokers come aboard, and is painful to extend or refactor. I therefore need an API layer that is fast, horizontally scalable and, above all, maintainable. No usable documentation exists, so part of the assignment is to reverse-engineer the relevant business rules directly from the running application and stakeholder interviews. You will model the core insurance domain into aggreg...

The goal is to turn my vision into the most recognised online destination for buying physical electronics worldwide. I already know the store will sell only tangible tech products—phones, laptops, smart-home gear, accessories—so every part of the build should feel purpose-built for that niche. Core experience • Lightning-fast catalogue browsing and an advanced yet intuitive search so visitors can jump from product idea to checkout in seconds. • A rock-solid checkout that supports multiple payment options out of the box—major cards, PayPal, local wallets, and room to plug in new gateways later—without ever compromising security or PCI compliance. • Scalable architecture (micro-services or modular monolith, whichever achieves high traffic toleran...

I’m ready to move our Kubernetes workloads on AWS into a fully automated production-grade release flow and need an expert who can stand up Spinnaker via the Spinnaker Operator to make that happen. Here’s what I’m after: • Install and configure the Spinnaker Operator on an existing AWS-hosted Kubernetes cluster, ensuring all CRDs, accounts and namespaces are in place. • Define a clean, repeatable deployment pipeline that promotes images straight to production once tests pass, complete with rollback logic and automated approvals where necessary. • Wire Spinnaker to the AWS services it needs (ECR, IAM roles, load balancer annotations, etc.) so artefacts and infrastructure are discovered without manual steps. • Document the setup: Helm/​kubectl...

I want to demonstrate provable data consistency across a geographically distributed Hyperledger Fabric network by persisting the blockchain ledger in CockroachDB instead of the default back-end. The work centres on two Fabric layers: chaincode and the ledger itself. Chaincode reads and writes must be routed so that every block committed by a peer is durably stored in CockroachDB, and peers must replay that data with no divergence even under node failure or network partitions. The scope includes mapping Fabric’s block and state data structures to a CockroachDB schema, wiring the peer so that commit and endorsement steps call the database seamlessly, and validating the design with a small multi-region testnet. CockroachDB will act strictly as the ledger store; MSP and other services r...

I’m looking for a skilled technical writer who can turn our complex platform into clear, structured system architecture documentation. This is strictly technical writing for software documentation, with a focus on mapping out how each service, module, and data flow fits together. What I need from you: • A high-level architecture overview diagram showing all core components, services, and external integrations. • Detailed written descriptions of each component, including purpose, key technologies, dependencies, and failure considerations. • Data-flow and sequence diagrams that explain how information moves through the system during typical use cases. • Deployment topology outlining environments (dev, staging, prod), hosting details, and scaling strategy. &...

I am building an enterprise-grade, stealth monitoring solution dedicated to Android 14 devices and I need a senior security engineer who can take it from proof-of-concept to a production-ready SaaS platform. What the agent must do The core of the job is a lightweight background service that captures user activity—specifically app-usage timelines, every keystroke, and continuous location—even under the new Android 14 background-execution limits. All data has to be streamed in real time, encrypted end-to-end (AES-256 at rest, TLS 1.3 in transit), and made available for remote access from a web console. Zero-root, zero-popup, and zero-battery-drain are non-negotiable. How the platform should feel Think managed SaaS: multi-tenant, horizontally scalable, sub-second ingest for ...

I’m building a product, not a demo and not a quick MVP. I’m looking for a a small and strong team who wants to help build something foundational and stay involved, not someone who just wants to close a ticket and move on. The work is split into two tightly connected parts: 1) Code name - RAYA This is the core platform. RAYA is an AI orchestration system — basically the “brain” that handles AI workflows, task routing, logic, decision layers, and integrations. It’s not tied to one product. The idea is to build this once, properly, so it can power multiple products over time. Think platform first, product second. 2) Code name - LEO LEO is the first real product built on top of RAYA. It’s focused on jobs, talent, hiring workflows, 6 other field niche a...

I’m building a full-scale e-commerce solution and I want every piece—web store and mobile apps—running on a clean microservice architecture. The core idea is to separate catalog, cart/checkout, payments, user management, and notification services so they can scale independently and be deployed through containers without downtime. For the customer-facing side, I need: • A responsive web application that feels fast on desktop and mobile browsers, complete with product search, detailed pages, real-time inventory, shopping cart, secure checkout, and an admin dashboard for product and order management. • Native (or high-performance cross-platform) iOS and Android apps. Both apps must include secure user authentication and push notifications for order updates, prom...

I’m looking for a senior systems architect to design the technical foundation for a payment-gated booking network that controls access to real-time, high-demand service slots. From the user’s perspective, the flow is simple: select a slot → pay → receive instant confirmation. Behind the scenes, the platform must reliably handle concurrency spikes, subscription validation, atomic booking, and fast payment settlement, while guaranteeing zero double-booking. This is an architecture-first engagement. No UI or app build is required at this stage. Core Objectives Model the end-to-end flow for payment-gated real-time bookings for high-demand services. Design a subscription layer that wraps booking access. At launch we will offer a single monthly plan; the architecture m...
