I'm developing a mobile and desktop app using React, TypeScript, Vite, Tailwind CSS, Supabase, and PostgreSQL. I need custom chat bubbles that act like expressive avatars. The outer shell of the bubble should communicate body language. A shy or nervous speaker might have a softer border, faded edges, smaller presence, slight trembling, or hesitant pulsing. An authoritative speaker might have a thicker border, sharper shape, stronger contrast, steadier animation, and more visual weight. An intimidated speaker might shiver, compress slightly, or flicker at the edges. An injured speaker might crack, glitch, drip, or destabilize. The text itself should communicate vocal cues. Words can shake when scared, stretch when strained, enlarge when emphasized, fade when whispered, blur ...

... v14, NestJS, PostgreSQL, , and Stripe. The immediate, highest-priority task is a thorough refactor of the existing legacy codebase so we can eliminate the high server response times that are slowing checkout and catalogue pages. Once the worst bottlenecks are gone, the roadmap continues with clean REST/GraphQL APIs and a hardened Stripe integration, all built with TDD and modern best practices in mind. You’ll be working inside a GitHub repo with CI already wired for Jest and ESLint; every merge must keep tests green and Lighthouse scores healthy. Key context you should know: • Current pain point: performance inefficiencies, specifically high server response times. • Tech already in place: 14 on the front end, NestJS services layer, PostgreSQL ...

The immediate focus is on the CRM, Inventory Management and Accounting modules, where I’d like new features built, existing logic adjusted and persistent bugs resolved. The end goal is seamless integration with several external systems—most urgently a WhatsApp API—but I also have other data sources waiting in the wings. You’ll be diving into Python code, PostgreSQL queries and the Odoo framework itself, so rock-solid experience with v16 or v17 is essential. Part of the job is troubleshooting errors as they pop up, then packaging fixes into clean, reusable modules that survive upgrades. I also rely on your guidance for server deployment and routine maintenance; automation scripts or Docker know-how are a plus because I ...

I need a clean, scalable backend drafted from scratch, starting with a solid PostgreSQL schema. The heart of the project is a referral module that pays out cash rewards when invitees convert, so the data model, triggers, and calculation logic must revolve around that requirement. Here’s what I’m expecting: • Database design in PostgreSQL, including all DDL scripts and a concise ER diagram. • Core API endpoints (or documented stored procedures) that record a referral, verify the qualifying event, and trigger the cash-reward payout. • Clear unit or integration tests demonstrating the reward rules in action. While tracking links or status updates are not mandatory right now, structure the tables so those features can slot in later without rewr...

The integration must talk directly to the Charles Schwab API, so proven experience with that specific broker is essential. What’s left to build • State logic: every open position and pending order must be tracked continuously, with status updates saved to my PostgreSQL instance and pushed to Telegram in real time. • Complex orders: the flow has to create, monitor, and — when required — cancel OCO (One Cancels Other) orders using Schwab’s REST endpoints. • Kill switch: a single flag in n8n (manual boolean, plus an optional webhook) should immediately cancel every open order and stop ...
