...projects—they actively collaborate in real time. The core of this phase is a live coding environment that lets multiple users share and edit the same file, jump into true pair-programming sessions, and enjoy the creature comforts of modern editors such as syntax highlighting and auto-complete. Think Google Docs fluidity, but for code. Here’s what I need delivered: • A browser-based editor (Monaco, CodeMirror, or similar) wired for simultaneous multi-cursor editing. • WebSocket or WebRTC infrastructure that keeps sessions in sync with minimal latency, even when several participants are connected. • Built-in pair-programming mode—one user drives while another follows, with quick role-swap. • Robust syntax support (at minimum J...
...and scanned financial records into clean, searchable data inside my PostgreSQL database. All source documents are organised by month in shared cloud folders; your job is to review each file, capture every relevant field, and insert it directly into the tables I specify (or propose a tighter schema if you spot improvements). Accuracy matters more than speed—balances must tie out and numeric formats must stay consistent with the existing data. I’ve already set up secure, limited-privilege access to the database, and can supply ER diagrams plus sample rows so you see the conventions to follow. If you prefer to stage the work in a local instance before pushing to production, that’s fine with me. Deliverables • Populated PostgreSQL tables reflecting all...

My heating installation is already wired with motorised valves and PT-100 temperature sensors; what it still needs is a clean, reliable control program running on a Schneider Electric PLC. All field devices will communicate over Modbus TCP/IP, so the job centres on writing and testing the logic that opens or closes each valve, reads every sensor, and enforces the temperature set-points and safety limits I will provide. You’ll work directly in EcoStruxure Control Expert (Unity Pro), mapping the correct holding/input registers, building the sequence logic (ladder or structured text—your choice), and setting up alarms and manual-override modes. Once the code is ready, I’ll load it on site; remote commissioning support through VPN is essential to fine-tune timing and confirm...

I’m currently working through the “BCA topic” section of my Bachelor of Computer Applications course and have reached the data-structure unit that falls under the Programming Languages module. Everything is being assessed in C++, and I need focused help turning theory into clean, working code. What I’m looking for is straight-to-the-point guidance that covers the core ideas behind each structure and then shows how to implement, test, and analyse them in modern C++. I learn fastest when I can read well-commented source, step through it, and ask a couple of follow-up questions afterward, so please be comfortable explaining your choices as you code. Deliverables (all discrete): • C++ source and header files that compile with g++ 11 or later • In-co...

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...

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...
