Collaborative It Project Partner for Early Stage Development

Budget: 1500 USD Deadline: 1 day

Hi there,

As a Senior Full-Stack Engineer based in Germany and a native Ukrainian speaker, your search for an EU-based technical partner perfectly aligns with my background. I specialize in joining early-stage ventures to define the technical architecture, shape the product roadmap, and build scalable platforms from the ground up.

I operate as a registered independent contractor (Freiberufler) and focus entirely on long-term, collaborative partnerships rather than isolated tasks.

How I approach early-stage product development:

Pragmatic Architecture & Stack Selection: I help founders choose the right tools for their specific business goals rather than over-engineering from day one. My preferred stack for rapid, scalable web applications includes Next.js, React, TypeScript, and Node.js, which allows for quick iterations while maintaining a robust foundation.

End-to-End Execution: I recently architected and launched several custom SaaS platforms from scratch—including complex booking management systems and electronic invoicing tools. I handle the entire lifecycle, from database design and API integrations to delivering highly performant, mobile-friendly frontends.

AI-Native Efficiency: I actively leverage advanced AI tools and autonomous coding workflows (such as Claude Code and Windsurf) to significantly accelerate development cycles, automate testing, and deploy features faster without sacrificing code quality.

Strategic Collaboration: I bring a business-first mindset to the table. I will actively discuss the project structure with you, manage iterations through agile methodologies (Scrum/Jira), and recommend the most cost-effective path to launch our initial version.

I am highly interested in the foundational nature of this venture. I would be glad to schedule an introductory call to discuss your core idea in its current state, explore potential technology stacks, and determine how we can build a successful product together.

Best regards,

Serhii Makarov

Hello!

I am the founder of a company that specializes in both classical development and automation, as well as the implementation of AI tools.

I have quite a large expertise, enthusiasm, and a good tech stack.
I have launched several small SaaS solutions.

Let's discuss in what context you are considering collaboration, your idea in more detail, and think about how we can be useful to each other.

Hello Victor.

Briefly:

Your project will benefit from a technology stack chosen for long-term maintainability and speed of iteration, not just hype. For the early-stage web application, a Go backend with a Next.js/React frontend offers a clean separation of concerns. At the same time, Go's performance and simplicity keep infrastructure costs low as you scale. AI capabilities can be integrated directly via OpenAI APIs or self-hosted models like Ollama for data privacy, with pgvector enabling semantic search and RAG workflows without vendor lock-in. The initial version can be built using plain JavaScript to accelerate delivery, with TypeScript introduced later if the codebase complexity demands it. This approach ensures you get a working prototype fast, validated by real users, and a solid foundation for future iterations. The focus will be on delivering a dashboard that gives you clear insights and a backend that automates your core processes, so you can start gathering feedback immediately.

More details:

Shaping a product from a blank slate is where architectural decisions matter most — choosing a stack that stays cheap to run and easy to iterate on will free up your budget for features, not infrastructure. For an early-stage web platform with AI capabilities, a Go backend paired with a React/Next.js frontend keeps your infrastructure footprint minimal while giving you headroom for real-time features, dashboards, and API integrations. AI workflows can lean on OpenAI for speed-to-market or self-hosted models via Ollama when data privacy or cost control becomes a priority — pgvector on PostgreSQL handles semantic search and RAG without locking you into a single vendor.

Your first iteration will land as a working prototype validated by real users, not a slide deck. A dashboard surfacing your core metrics, an automated backend handling repetitive flows, and a clean API contract between layers will give you something tangible to iterate on within the first weeks. Starting with JavaScript for delivery speed and introducing TypeScript as the codebase grows helps keep initial costs low without sacrificing long-term maintainability.

I'm based in Ukraine and accustomed to long-term EU collaborations where roadmap discussions, honest tradeoff conversations, and shared ownership are the norm. Let's talk through your vision and map out the first concrete milestone. Expand

I am writing a complex backend on nodejs, express.js, next.js. Please write in private messages.

Hello, I’d be happy to join as a technical partner and help shape the project from the ground up, not just write code.

Since the idea is still being refined, I’d suggest starting with a short discovery phase: define the MVP scope, choose the right tech stack, plan the architecture, and create a clear development roadmap. After that, I can help build the core features, test the workflow, improve the UI/UX, and iterate based on feedback.

I have experience with web development, backend/frontend work, databases, API integrations, automation tools, and building scalable project structures. I’m comfortable working in an early-stage environment where requirements evolve and clear communication is essential.

I'm open to long-term collaboration.

Hi,

This kind of long-term, build-it-together setup is exactly what suits me — I prefer being involved from the architecture stage rather than picking up a finished spec.

Comfortable across the stack you listed: backend/frontend (Node.js — Express, NestJS, Fastify; also Vue, Python, Java when it fits), PostgreSQL/database design, API integrations, dashboards, and AI tooling. I have a live SaaS where I built an AI real-time chat from scratch (https://momicro.com) and an open-source backend you can look through directly — https://github.com/MoMicro-core/MoAssist-server — to see how I structure code and think about architecture.

Based in Ukraine, so the EU/Ukraine fit works on my end too.

Happy to get on a call and talk through the idea before locking in any direction — for an early-stage project like this, the conversation matters more than a pitch.

You're looking for a technical co-founder type to help shape and build a product from scratch, not just execute a spec.

My approach: start with a 2-3 session discovery to map the core user problem and identify the simplest testable slice, then propose a stack (likely Next.js + Node/Python backend + PostgreSQL, or adjust based on what the idea demands), then build a thin vertical slice of the core feature first so you can validate assumptions before we scale anything. AI integration and API work are areas I can contribute to early, not bolt on later. The architectural decision that matters most at this stage is keeping the data model flexible enough to pivot without a full rewrite.

What's the general domain of the idea, and do you have a rough sense of the primary user action the product needs to nail first?
