Hello,

I am very interested in your project and believe I am a strong fit for your team.

I have solid experience with Next.js, React, Supabase, Tailwind CSS, Vercel, API integrations, and AI-based automation systems. I have built and maintained scalable SaaS platforms, integrated third-party services, and optimized backend workflows using PostgreSQL and serverless functions.

I work independently, communicate clearly, and focus on writing clean, maintainable code. I am also comfortable working in remote freelance environments with flexible schedules.

I would be happy to contribute to your platform and help improve and scale the product.
…
Looking forward to discussing the project further.

Best regards

I am very interest and it's good fit for my skills.
Wanna take this chance.

Hello, Leon.
First, it's important to mention that I am also in Israel, Petah Tikva. We are in the same time zone, so we can communicate and have calls normally, and if desired, meet in person. It won't be possible with a team from another region.
Regarding the tech stack, everything is operational - Next.js, Supabase with RLS and Edge Functions, webhooks, deployment on Vercel. However, where I can really be useful for Kadmoo is in AI and automation. You have this indicated as a plus, although for a marketing automation platform, this is, in my opinion, the heart of the product.
Recently, I integrated GoHighLevel with Supabase through n8n: synchronizing CRM data with the history of funnel stages via webhooks. I created an AI platform with routing between providers (OpenAI, Anthropic), quotas, and usage tracking. And an automation loop with application processing, AI drafts, and manual confirmation before sending. So, my AI work is not just for show, but as a working layer over real data - through function calling or RAG based on your database.
A format of 15-20 hours a week works for me. I suggest starting with a small task so you can see how I integrate into the code and how it is to work with me, without immediate commitments.
What is currently a priority in terms of functionality?

Hello,
I’m a Full-Stack Developer with 17+ years of experience building scalable web applications, APIs, and cloud-based systems. I have strong expertise in .NET, React, Next.js, Angular, Node.js, SQL Server, PostgreSQL, Azure, and AWS.
Here are some stacks which I have.
Frontend and backend development
REST API integration and development
Database design and optimization
Cloud deployment and CI/CD pipelines
Bug fixing, performance optimization, and feature development
Responsive and modern UI implementation
… I focus on clean architecture, maintainable code, and reliable delivery. I can work independently, communicate clearly, and provide fast turnaround with high-quality results.
I’d be happy to discuss your project requirements and how I can help.
Looking forward to hearing from you.

Hello, I welcome you. Your plus is the integration of AI/LLM, and that is my main focus, so I will start with it.

I have developed a production voice and chat assistant (Telegram bots) with protection against hallucinations, tied to real business data — meaning AI is a working tool for me, not a demo. I handle long LLM calls in background jobs, and I send the status to the front end via Supabase Realtime to avoid hitting the Edge Functions timeout.

The rest of the stack is working daily: Next.js App Router + Tailwind, Supabase (RLS multi-tenancy, Edge Functions, real-time), webhooks through idempotent handlers, deployment and preview on Vercel. I maintain a part-time workload of 15–20 hours/week consistently, working autonomously.

I am ready to start with a small first task for you to evaluate my approach. What functionality is currently a priority?
In Russian (the client is from Rishon Lezion, all specifications and strongest bids are in Russian, so this option is more likely to be accepted):

Good day!

I have experience in developing SaaS systems, for example, momicro.com, where AI also plays a key role. In addition, I have experience with AI integration on a similar SaaS product https://ai-desk.ai/.
On both projects, I wrote the backend from scratch and also the frontend completely/partially. Both used React.
In total, I have over 4 years of experience with React and Next.js.
I have also worked with Supabase and PostgreSQL, for instance, in the project https://seetruth.app/

I can easily handle architectural solutions, database design, and more. I write clean and understandable code for possible future scaling.

Hello.

I am a fullstack developer with over 10 years of experience.

I work efficiently and on time. I can work with existing projects, other people's code, understand the essence of architecture, business models, and independently suggest improvements.

For the last 3 years, I have worked on projects such as online delivery qwqer.eu and hypermarket + delivery from restaurants "your store".

Before that, I worked for 6 years on the online taxi project iqtaxi.by, which I developed from scratch and brought to operate in a competitive market.
…
I understand that my experience may not fully match your project, but I grasp the essence of marketing, analytics, and business flow in general. This will not be a problem for me.

I also have considerable experience in integrating AI/LLM, agents and their orchestration, RAG, and more. Including the use of open-source models for local use where stable inference plays an important role.

Additionally, I have strong experience in designing, writing technical specifications, technical reports, audits, and I possess analytical thinking.

I have mainly worked on an hourly basis at around $20-30 per hour.

I am open to your proposals, even if it involves fixed payment.

Feel free to write, I would be happy to collaborate.

Hello, Leon.

I love this opportunity so much.

As a fullstack developer, the react/next.js and tailwind css is my main stack and I have extensive experience on supbase and github version control management and project deployment such as vercel.
You can check some of my examples on these links:
http://exeltiq.com/

…
Based on this experience I can work in this position as well, and can provide the perpect result.

Also I agree to this flexible work schedule and can start right now.
Feel free reach out to me any time and please share me the details so that I can start rigth now.

Thanks, Youssef.

You need not a "task executor," but an autonomous partner who will take on features, architecture, and integrations on Next.js + Supabase and will drive the product without micromanagement — this is my working style.

Here’s how I would approach your platform:
• I make RLS the foundation of multitenancy: isolation by tenant_id through policies at the Postgres level, not checks in the code. For SaaS, this is the only way to guarantee that data leaks between clients do not occur.
• I handle webhooks and third-party APIs (CRM, marketing tools) through Edge Functions with idempotency: key + deduplication. External services send retries, and without this, events get duplicated — a bug that a junior developer notices already in production.
• I move the AI workflow to background jobs (queue + worker) so that long LLM calls do not block requests and do not hit the timeout of Edge Functions; I send the status to the front end via Supabase Realtime.
• App Router: server components and server actions for data, preview deployment on Vercel for each PR — we roll out changes safely.

I work specifically on this stack (Next.js App Router, Supabase, LLM integrations), without legacy — just as you described. I consistently maintain 15–20 hours per week with a flexible schedule, in direct contact.
…
How many active clients are currently on the platform and where is the nearest bottleneck — load on the AI workflow, data volume, or speed of rolling out new integrations? This will determine the most sensible starting point for the first sprint.

Hello! I see the role: to join the development of the SaaS Kadmoo as a full-stack part-timer, new functionality on Next.js plus Supabase, architecture optimization, integration of third-party APIs, CRM, and AI agents, with a flexible schedule and direct communication with the founder.

The part-time format of 15-20 hours a week suits me, I am currently open to that. Everything matches regarding the stack. I work with Next.js and React, including App Router and Tailwind. I use Supabase as a managed wrapper over PostgreSQL, understand Row Level Security, Edge Functions, and real-time. I regularly handle integrations via REST and webhooks, with authorization and tokens, and deploy through Vercel.

Where I can be especially useful is in the AI part. I have production experience with OpenAI and Anthropic API, I have released a voice AI assistant with RAG on top of vector search, and an AI platform with semantic search. So, I create AI workflows and agents not as a hype, but as a working layer on top of your database, through function calling or RAG based on Supabase data, so that automations rely on real client data.

I work autonomously, with clean code and documentation, through branches and pull requests. I am ready to start with a small first task so you can assess how I integrate into the codebase. Please let me know which upcoming functionality is a priority and which integrations or AI scenarios are currently the most urgent?

Kadmoo needs a Full-Stack developer for part-time work, capable of developing a SaaS automation platform without bureaucracy. I understand that the key task here is not just interfaces on Next.js, but a reliable backend on Supabase with RLS configuration and Edge Functions for integrating external APIs and AI workflows. I will take on the autonomous development of features and seamless deployment on Vercel.
I have extensive experience with Next.js, Tailwind CSS, and Supabase. I often integrate third-party APIs and LLM models. To give you an idea of my approach to secure Edge Functions, here is a code example:
const handler = async (req) => {
const { user } = await supabase.auth.getUser(req.headers.get('Authorization'));
if (!user) return new Response('Unauthorized', { status: 401 });
return new Response(JSON.stringify(await runAIWorkflow(user.id)));
};
I am ready to join the project for 15–20 hours a week starting tomorrow if you share access to the repository.
