Summary We’re building a fast, modern sports fixtures + TV schedule platform at [login to view URL], and we’re looking for one strong, reliable backend lead to help us finish the job properly and ship with confidence. We care about speed, quality, and teamwork. We keep communication simple, we demo working progress daily, and we support each other to get the best result. If you’re the kind of person who enjoys owning delivery and shipping clean systems, you’ll fit right in. The project (in plain English) The product is already well underway. Your job is to take ownership of the backend delivery and bring everything together cleanly. The frontend workstream (PWA / web / iOS / Android) relies on a stable backend contract — you’ll lead that contract so integration is smooth. We use external sports data sources today and the architecture must be ready to add more providers later without rewrites. There is also a venue display advertising pull layer that needs stable, fast endpoints/feeds. Your role (what you’ll own) You are the backend delivery owner for this sprint. That means you don’t just write code — you keep the whole backend moving forward, unblock integration, and ensure we ship working outcomes. Week 1 goal: everything connected and fully operational Week 1 is the most important week. By the end of Week 1, we want a fully working end-to-end system in staging: Full end-to-end integration working Backend endpoints stable and returning correct, predictable data All required frontend sections connected and fully operational (not “wired up but flaky”) Data flow stable and consistent Venue display advertising pull connected and working (fast, cache-friendly outputs) PWA live on staging and functioning end-to-end Staging reliability from day one Repo running locally quickly and cleanly Staging dependable and deploys repeatable Clear setup documentation (including env/secrets) Basic CI checks in place (lint/tests/build) Backend structure + admin usability Strapi organised cleanly (content types, permissions, roles, policies, naming) New admin GUI design implemented and functioning (layouts, fields, relations, workflows) Permissions safe-by-default and easy for the team to use API contract and provider abstraction A clean v1 API contract for the pages we ship first Frontend consumes your contract (not upstream quirks) Normalisation + caching + throttling/rate limits in place where needed Postman collection kept accurate and updated (OpenAPI is a bonus) Security + performance baseline Tenant/venue isolation enforced properly: Tenant context from JWT only Enforced in Strapi policies + service layer Never trust client-supplied venue/tenant IDs Negative tests proving venue A cannot access venue B Input validation, auth hardening, and rate limiting where needed Sensible DB hygiene (indexes and query sanity) Background jobs & queues Idempotent workers Retry/backoff rules Clear logging and visibility into failures Safe re-run strategy when something goes wrong Documentation that stays current Runbook started immediately and updated as you go: setup, deploy, rollback/restore, queue debugging Practical handover notes so the next developer can continue smoothly How we work (team-first, no lone wolf) We ship quickly because we collaborate closely. You’ll never be left alone to guess what we want — we discuss decisions early, remove blockers fast, and keep the whole team aligned. Daily rhythm: Start of day: short meeting + plan (what will ship today) During the day: quick updates when PRs are ready or blockers appear End of day: what shipped / what’s next / blockers Next-day plan: submitted at end of day so I can review early and support you We want a positive working relationship and a smooth delivery rhythm. Compensation (simple and friendly) Total: $1,000 for the 1-month full-time sprint $600 placed into escrow in stages and released on completion (verified working) $400 bonus paid on completion if KPIs/objectives are fully met (delivery, reliability, collaboration, and timelines) What “completion” means At the end of the month we should have: Stable staging + repeatable deploys Secure tenant isolation proven with negative tests Queues/workers reliable with good failure visibility v1 API contract stable and documented (Postman current) PWA and the frontend/mobile workstreams fully integrated with stable endpoints Venue display advertising pull working reliably Clear documentation + handover notes delivered We aim for everything to be submitted and live across web/PWA and mobile where platform review timelines allow. If app store review introduces timing, your responsibility is that the backend and integration are ready and stable so submission is smooth and fast. Must-have skills Hands-on Strapi v5 Node.js + TypeScript PostgreSQL Redis + background jobs/queues (BullMQ or equivalent) API contract design + versioning Multi-tenant security patterns + negative testing Strong delivery ownership and clear communication Nice-to-have CI/CD basics, observability basics Experience taking over existing projects and shipping quickly Performance tuning and security hardening experience Quick application questions (so we can move fast) In your first message, please answer: How do you enforce tenant isolation in Strapi (policy + service layer)? How do you handle idempotency + retries/backoff in background jobs? How do you design a clean API contract that hides provider quirks from the frontend? What are your first 10 actions in Week 1 to get staging stable and integration working end-to-end? Can you overlap ICT 06:00–15:00 daily for the full month? Final note AI, copy and paste - will be deleted We’re genuinely excited to find the right person and build a great working relationship. If you’re dependable, proactive, and enjoy shipping real products with a collaborative team, we’d love to talk.

Hello, I have carefully analyzed your requirements and recently took ownership of a Strapi v4 backend for a live sports data platform, stabilizing multi-tenant APIs, normalizing multiple external providers, implementing Redis caching, BullMQ workers, and delivering a clean API contract consumed by PWA and mobile apps in production. Your project requires strong Strapi organization, strict tenant isolation, stable provider abstraction, background jobs with retries, and predictable API contracts, and I will address this by enforcing tenant context from JWT in Strapi policies and service layer, designing provider adapters behind a normalized service, implementing idempotent BullMQ workers with retry/backoff, building a clear v1 API contract, setting up caching, rate limiting, and ensuring staging is reliable with CI checks and documentation. I am available to begin work immediately, can overlap ICT 06:00–15:00 daily, and am committed to delivering the highest quality backend within the shortest possible timeframe. Best regards, Elenilson

Hello! Week 1 usually fails when the backend contract is unstable and tenant isolation is leaky, so I’ll lock a clean v1 API, prove isolation with negative tests, and make staging deploys repeatable from day one. First I enforce tenant and venue context from JWT only using Strapi v5 policies plus the service layer, never trusting client supplied IDs, and I add tests showing venue A cannot read venue B. Next I design a provider adapter layer that normalizes external sports feeds into stable DTOs, then the frontend consumes predictable endpoints that do not change when you add new providers. Then I implement Redis caching, rate limits, and fast venue display advertising feeds, plus clean Postman collection and optional OpenAPI. After that I set up BullMQ workers with idempotency keys, retries with backoff, dead letter visibility, and structured logging for quick debugging. I can overlap ICT 06:00 to 15:00 daily and I’m comfortable with daily demos and owning delivery. Warm regards, Yulius Mayoru

Hi Marc, I will implement a data normalization layer within Strapi to shield your frontend from the volatility of external sports providers. This strategy ensures the API contract remains stable and predictable even when upstream data formats change or providers are added. I led the development of similar multi-tenant architectures for construction management and real-time trading platforms using Node.js and PostgreSQL. These projects involved enforcing strict data isolation and managing high-volume background jobs for live market data updates through the Kite API. I will focus my initial actions on securing tenant isolation through Strapi policies and stabilizing the BullMQ workers. I will implement idempotent logic to ensure that frequent sports data refreshes do not result in record duplication or race conditions during peak hours. Does your current setup encounter performance issues during peak fixture hours when background jobs process large data volumes? I am interested in hearing more about your specific scaling goals for the platform. Are you available for a quick chat?

Hello, I am confident I can lead backend delivery for SportsFixtures.net. Tenant isolation in Strapi is enforced through JWT context only, validated in policies and service layers, with negative tests proving no cross‑tenant access. Background jobs use Redis with BullMQ, ensuring idempotency by unique keys and retries with exponential backoff plus clear logging. A clean API contract is achieved by abstracting provider quirks into a normalization layer so the frontend consumes predictable schemas. My first actions focus on stabilizing staging, connecting data sources, securing endpoints, configuring queues, and documenting setup to ensure smooth integration end to end. Yes, I can overlap ICT 06:00–15:00 daily.

Hello, I’ve worked on a healthcare scheduling platform where multi-tenant security and backend reliability were crucial. Here’s how I’d approach your project: Tenant isolation in Strapi is enforced by combining policy checks with service-layer validation. For each request, I extract the tenant context from the JWT, then ensure policies block cross-tenant data access, with negative tests verifying enforcement. For background jobs, I design idempotent workers by tracking job IDs and state. Retries use exponential backoff with capped attempts, logging failures clearly for fast debugging. To hide provider quirks, I build a clean API contract that normalizes all data inputs and caches responses to ensure fast, consistent outputs. Versioning the API allows evolving it without breaking frontend integration. Week 1 actions include: 1. Clone repo and set up local & staging environments flawlessly. 2. Validate all environment variables and secrets. 3. Solidify tenant isolation and run negative tests. 4. Connect and stabilize sports data sources. 5. Build and finalize API contract. 6. Verify backend endpoints with frontend hooks. 7. Ensure caching and rate limiting work. 8. Integrate venue advertising pull. 9. Set up CI checks and deployments. 10. Deliver clear documentation and runbook. I can work 06:00–15:00 ICT daily. Ready to dive in and get everything stable and integrated by week’s end. Let’s get started.
