Hi Freelancers,

We are looking for an experienced Frontend Developer to help us implement UI enhancements and fix several UI-related bugs for our web application, "Story Stream" (built with React, Next.js, Tailwind CSS, and Supabase). Story Stream is a tool designed to help writers analyze and structure their books.

This project involves tackling a specific list of UI-focused tasks derived from our GitHub issues. While backend familiarity (Supabase) is a plus, the core work is frontend implementation and refinement.

Project Scope & Key Tasks:

We have a list of approximately 14 specific tasks defined in GitHub issues (access will be provided). These tasks primarily involve:

UI Implementation from Figma: Updating key pages/components (like the Book Home Page and Roadmap views) to match provided Figma designs.
Component Enhancements: Improving existing UI elements (e.g., using Character Cards instead of table rows, adding Breadcrumbs, fixing navigation display issues).
Data Display & Status Updates: Implementing UI elements to show background task processing status and fixing issues with data display (e.g., colors, labels, categorization on the Roadmap).
User Experience Improvements: Addressing issues like empty states (no books), fixing logout functionality, handling browser back button issues after Stripe interaction, and re-enabling purchase checks.
Bug Fixing: Resolving specific UI bugs detailed in the GitHub issues (e.g., markdown display errors).
Required Skills:

Proven experience with React
Strong proficiency in Next.js
Expertise in Tailwind CSS for styling
Solid understanding of JavaScript/TypeScript
Experience with Git/GitHub workflow (pull requests, issue tracking)
Ability to translate requirements (GitHub issues, Figma designs) into clean, functional UI code
Strong communication skills
Bonus Points:

Experience with Supabase
Experience directly implementing Figma designs
Previous work on SaaS applications
Budget & Payment:

This is a fixed-price project.
Our budget is approximately $2000 USD for the completion of the defined list of tasks.
We prefer a fixed-price structure to ensure clarity on deliverables and budget, rather than hourly tracking. Please bid based on delivering the completed tasks.
To Apply:

Please submit your proposal and include:

A brief summary of your experience with React, Next.js, and Tailwind CSS.
Links to 1-2 relevant projects in your portfolio that showcase your UI development skills.
Confirmation that you are comfortable working on a fixed-price basis for the scope outlined.
(Optional) Any initial thoughts you have on tackling these types of UI tasks.
We are looking for someone who can dive into the existing codebase, understand the requirements from the GitHub issues, and efficiently deliver high-quality UI updates.

We look forward to hearing from you!

How comfortable are you with the occasional ping to put out a fire on the weekends? (only happens with an enterprise client of mine but worth noting it's a possibility)

I set up an "agency" website to help solidify this collaboration as a tangible thing. As my partner in this venture I'm hoping we can help each other gain and retain clients. I'm also looking for a designer to add to the team down the line. Working on developing a business plan and setting up and LLC. Here's the agency website: https://bluenebula.dev/

What I need from you:
- Short intro about yourself with a description of your experience and your most notable skills and impact.
- Your portfolio of projects
- Highlight 2-3 of them and provide a description of what you did and what your impact was.

I'm building a consumer-facing service where users receive curated sets of multi-step tasks to be completed in preparation for an occasion. These tasks are unrelated but are all meant to be completed by the same person in a time-efficient way.
I need a developer to build an algorithm that takes several independent, structured task lists each with multiple steps and merges them into one time-optimized step-by-step plan. The goal is to minimize wasted time and maximize flow, so that the user can execute all tasks efficiently from start to finish.
Content creators will input these tasks into a structured format dictated by your algorithm, and end-users will select which ones they want to complete. The algorithm will then generate a combined, streamlined sequence that considers step timing, dependencies, and logical ordering.
I’ll be happy to share more details privately, but I’m keeping the broader concept discreet here as it includes some unique elements.
What I’m Looking For:

● Someone who can design and build an algorithm that sequences steps from unrelated tasks into one optimized flow

● Comfortable working with structured data, basic time estimates, and step dependencies

● Can produce clean, well-documented code that integrates with a structured database

● Can translate high-level functional descriptions into code and work collaboratively with a non-technical founder

Nice to Have:
● Experience with scheduling, sequencing, or optimization problems

● Familiarity with Python or JavaScript/TypeScript

● Bonus if you have experience thinking about user flows or task orchestration


This Project Is:
● A one-time contract with potential for additional work

● Part of a larger project that blends content curation, personalization, and user-driven customization

● Ideal for someone who enjoys creative logic puzzles and clean, modular problem-solving

If this sounds like something you’re interested in working on, please reach out.

I need someone to build an MCP server for me using the HTTP streaming method using the MCP SDK Typescript. This only needs to only have one tool for the Featurebase (create post), and I need to be able to deploy it immediately on Vercel. This MCP server will be used in an OpenAI agents SDK, so it needs to be ready to use out of the box. I only need one tool because I just need the template of the project structure set up.

The delivery needs to be in a GitHub repo that can be immediately deployed to Vercel.

Skills: TypeScript, Web Development
