The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I ne...

...between users. Users will be able to register, see their balance, send/receive funds, and request withdrawals. There will be an admin side to review users, approve/reject transactions, and manage settings. Current status Basic bot is already started using Node.js, Telegraf and PostgreSQL. Some database tables and commands are implemented, but the project is not production-ready yet. Code needs review, cleanup, and completion of missing features. Main tasks Review the existing Node.js / Telegraf code and PostgreSQL schema. Fix bugs, optimize structure and make the code easy to maintain. Complete core flows: user registration and referral (if needed), deposit / balance update logic, send / receive / internal transfer flow, withdrawal request and admin approval,...

...product. The core idea is simple: users open the app and immediately see fresh, well-structured content that I publish through an admin dashboard. Clean navigation, quick load times, and an intuitive layout are critical. Here is what I have in mind: • Cross-platform build using Flutter or React Native so we keep a single codebase. • A lightweight backend (Firebase, Supabase, or a Node + PostgreSQL stack) that lets me log in, create articles, tag them, and push updates instantly. • Push notifications the moment new content goes live. • Basic user analytics so I can track reads, session length, and popular topics. • Solid offline caching so articles remain viewable without a signal. • Store-ready assets: app icons, splash screens, and scre...

SCOPE AND ARCHITECTURE ADHERENCE The published technical requirements and stack (Python, PostgreSQL as source of truth, Redis for locking, Binance integration, Docker deployment) are the priority baseline for this project. If you propose architectural changes (e.g., different database, alternative execution model, third-party services, or different infrastructure), you must provide clear technical justification explaining: • Why the change improves robustness or reliability • How it preserves deterministic state and idempotency • What trade-offs are introduced • Why it is superior to the baseline stack "Unjustified stack substitutions or generic alternatives will not be considered" OPTION A – Hybrid (Binance + 3Commas) Senior Python Enginee...

...reconcile it continuously. • Track every offer, update the user’s balance in real time and flag failed or stale trades for manual review in an admin panel. Admin / Back-office A lightweight dashboard is needed for live game monitoring, user bans, bot status and manual item adjustments. Tech & Delivery I’m comfortable with common stacks such as Node.js, TypeScript, React, MongoDB or PostgreSQL, but I’m open to alternatives if they keep latency low and the interface snappy. Please outline your chosen stack, timeline and any hosting requirements when you reply. Acceptance criteria 1. Site replicates Bloxybet’s UX/UI closely (no original copywriting required). 2. Unlimited simultaneous coin-flip rooms run without lag. 3. Jackpot a...

...growth I’m restructuring the entire infrastructure and codebase for true horizontal scale, bullet-proof uptime, and lightning performance. Here is the current landscape you’ll step into: • Native iOS & Android codebases that need profiling, refactoring where necessary, and tighter CI/CD. • A Laravel monolith that must be modularised, cached with Redis, and tuned for very high concurrency. • PostgreSQL instances approaching their limits; we’re ready for partitioning, read replicas, and autoscaling. • Alibaba Cloud services (ECS, RDS, OSS, SLB) underpin everything, though I’m open to architectural suggestions, even hybrid or multi-cloud, if they offer measurable benefit. • Real-time websockets for live video, chat, not...

...already in place, but the UI needs a visual and usability upgrade before we move forward. Beginning tomorrow, I’d like you to step in, take ownership of the codebase, and carry the project all the way to production. On the backend I’m leaning toward Node.js, yet I’m flexible on the stack if you can justify clear benefits. Our database is still open for discussion—feel free to propose SQL (MySQL, PostgreSQL) or NoSQL (MongoDB, etc.) solutions that best fit a live-service game. Whichever route we pick, clean schema design, migration strategy, and security best practices are essential. Core scope • Fix and polish the existing frontend, focusing specifically on user-interface design so it looks and feels like a modern game portal. • Architect and...
