Project details
You will get a clean, production-ready SaaS MVP built for launch, testing, and future growth.
I work with founders and early-stage teams who need more than just code. I help define the fastest path to a usable product, keep scope focused, and build the core features that matter most in version one.
This project is ideal if you need a strong technical partner to turn your idea into a working SaaS product with a solid full-stack foundation.
Depending on scope, your MVP can include:
• product scoping and technical planning
• Next.js frontend
• Node.js backend or API routes
• authentication
• database setup
• core user flows
• Stripe billing
• admin dashboard
• deployment-ready setup
I focus on practical execution, clear communication, and maintainable architecture so your MVP is not just fast to launch, but also easy to improve after release.

Alex is fantastic to work with. He immediately understands a project, what needs to be done, and how to do it fast. I have worked with countless developers over decades, and I would hire Alex again (and fully intend to) in a heartbeat.

Two ways I can help:
1. YOUR AI-BUILT APP IS STUCK
You built with Lovable, Bolt, Cursor, or Claude Code. Now every fix breaks something else. Auth, payments, and deploy won't come together. That is the work I do.
- Full code and security audit in 5 days. Written report, every issue ranked by severity.
- Fixes in 2-3 weeks. Fixed scope and fixed price, agreed before we start.
- No-rewrite policy. I fix your codebase, not replace it.
- 2 weeks of post-launch support included.
What I find and fix most often: exposed API keys in client-side code, missing Supabase row-level security, runaway OpenAI spend with no cost limits, broken auth and sessions, no multi-tenant data isolation, zero error handling or logging.
2. YOU NEED AN AI SAAS BUILT RIGHT FROM DAY ONE
Recent products I shipped end to end:
- Excello. AI voice coaching platform. LiveKit, ElevenLabs, Tavus, Stripe. Real-time voice sessions with natural turn-taking.
- AuditMake. Multi-tenant AI audit pipeline. OpenAI, Supabase RLS, PDF generation, Docker.
- DailyJobs. Job matching platform. NestJS microservices, RabbitMQ, Redis, AI-powered matching.
- WildfireArt. AI art platform. HuggingFace models, blockchain token integration, Redis, Supabase.
AI AND LLM
OpenAI API (function calling, streaming, Assistants API), RAG pipelines (LangChain, LlamaIndex), vector search (pgvector, Pinecone), AI voice agents (LiveKit, ElevenLabs, Cartesia, Tavus), Whisper speech-to-text, conversational memory with summarization, async LLM processing with Redis queues, LLM observability and cost controls, structured extraction with Zod, AI document processing (PDF, DOCX, XLSX).
FULL STACK
Next.js (App Router, Server Components, SSR/SSG), React, TypeScript, Node.js, NestJS, Supabase (auth, database, realtime, RLS), PostgreSQL (pgvector, JSONB, triggers, migrations), Stripe (subscriptions, Connect, metered billing, webhooks), Redis, RabbitMQ, multi-tenant architecture, RBAC, admin dashboards, Docker, CI/CD, Vercel, Railway, AWS, DigitalOcean.
HOW I WORK
- Fixed price or hourly, your choice. Scope agreed in writing before we start.
- Daily updates. You always know where the project stands.
- I write the code myself. No hand-offs, no juniors.
