    FIREBASE TO MongoDB
    6 dias left
    Verificado

    Hi, I’m looking for an expert who can help me replace my current Firebase backend with MongoDB on my server. The migration involves about 2 GB of data and there are around 10 collections such as products, categories, pages, etc. I need to keep a similar structure so it continues to work with the existing project. The website is currently working perfectly and I want it to continue working the same way after the replacement without breaking anything. Thank you.

    Overview I’m building an AI-powered wedding planning platform and need a senior-level full-stack engineer to take over integration and evolution of the product. This is not a simple embed task. The core AI product already exists in and is deployed. A Webflow marketing site has also been built. The next stage is to properly integrate the two, refine the architecture, and continue evolving the product into a scalable SaaS platform. I’m looking for someone who can think beyond implementation and help shape a production-ready system. ⸻ Current Architecture Application Layer • 15 (App Router) • React 19 • Hosted on Vercel • OpenAI integration (AI wedding planner) • Clerk authentication • Stripe billing • Supabase / Postgres database...

    Looking for a full-stack developer to build Stitchin from scratch. Every creator gets a branded subdomain () with a bio builder, stories blog, digital products storefront, mini CRM inbox, and email subscriber list. Tech stack is fixed: 14 (App Router) + TypeScript + Supabase (auth, DB, storage) + Razorpay + Resend + Vercel. No WordPress, no Laravel, no custom backend. What exists already: A fully designed HTML/CSS/JS prototype of the entire builder UI (all screens, interactions, phone preview) — you are converting this to , not designing from scratch. Complete technical blueprint provided on day one: database schema (7 tables), middleware code for subdomain routing, API route patterns, RLS policies, environment variables, and a 14-week delivery timeline broken into weekly milestone...

    I need a full-stack partner to turn my idea into a polished, hosted site that combines three core experiences in one place: a concise bio page, a “story” feed for regular updates, and a storefront where I can sell my own e-books directly to readers. Here is what I have in mind. Visitors land on a sleek, mobile-first profile that feels as simple to navigate as Linktree, yet is entirely custom. From that hub they can: • jump to any external link I choose, • browse short, Instagram-style stories I post, and • purchase my digital titles without leaving the site. To make that happen you’ll take care of both the front end (modern, aesthetic templates that I can swap or tweak later) and the back end (a clean database schema for user accounts, product files...

    I have a live feed packaged as MPEG-DASH (.mpd plus segments). I need a lightweight bridge that ingests that stream in real time and simultaneously publishes it as adaptive HLS and as an RTMP push to any endpoint I specify. You have to use FFmpeg and nginx whichever keeps latency low and the workflow stable on a Linux server. Deliverables • A script or systemd service that pulls the MPD, repackages to HLS/MPEG-TS/ MKV/ MOV, and pushes RTMP to a configurable rtmp:// URL • Minimal transcoding: only re-encode if absolutely required for compatibility • Clear setup notes so I can replicate the solution on another machine • Acceptance: output should be rtmp and hls or http stream * kidkey ivkey , select type quality type when url synched, select option to stream push to x s...

    I have a production site that already looks and functions well, yet still feels sluggish in places and under-delivers on SEO metrics. I’ve gathered a clear, itemised list of problem areas—slow initial paint on key pages, Core Web Vitals warnings, and inconsistent behaviour on smaller screens—and I’m ready to hand that list over the moment we start. Your main brief is performance optimisation, with three targets in mind: • Lightning-fast page-load speed • Noticeable gains in SEO performance (especially Core Web Vitals) • Rock-solid mobile responsiveness The codebase is React 18 / 13. You’ll have access to the repo, build pipeline, and my Lighthouse/GTM data. If you prefer TypeScript, you’ll fit right in; the project already uses i...
