Hire the Best Minimum Viable Product Professionals

I build complete, production ready web applications, from full SaaS platforms to internal tools and AI-powered products. Startups and businesses hire me to take an idea all the way to a live, working product: architecture, frontend, backend, database, auth, payments, deployment. Not prototypes, real software that ships. I work across the entire stack, so you get one developer who can own the whole build instead of stitching together three. My own SaaS, Bidly (bidly.space), is an AI proposal tool built on Next.js, Convex, Clerk, and the Claude API, live and used by real freelancers. I build for clients the way I build for myself. What I deliver: ✅ Full-stack web apps & SaaS platforms, end to end ✅ Clean, scalable codebases built to grow, not throwaway demos ✅ Real AI integration — Claude & OpenAI APIs, not bolt-on gimmicks ✅ Clear communication and clean handover your team can build on Recent work: 🔹 RealTalk Referee — AI relationship-analysis app (React/TypeScript, Supabase, Stripe, Claude API), live at app.realtalkreferee.ai 🔹 Bidly — my own AI SaaS (Next.js, Convex, Clerk, Claude API), live at bidly.space 🔹 Enterprise HTML email build for a Globe Life company — pixel-perfect from Figma, deployed in Iterable 🔹 Laid — real-time PWA with live session sync, voting, and admin panel (Firebase) Tech stack: -Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS, et cetera -Backend: Node.js, Express, Convex, Supabase, PostgreSQL, MongoDB - Auth & Payments: Clerk, NextAuth, Stripe, PayPal - AI: Claude/Anthropic API, OpenAI API, AI agents, automation - Deployment: Vercel, Railway, Netlify, AWS, et cetera Whether you need a SaaS MVP, a web app, or AI features added to an existing product, I can take it from idea to launch. Let's talk.

I work with startups, SaaS companies, and AI businesses to design, build, and launch digital products that users actually use and investors take seriously.

Most AI agents demo beautifully, then break the moment real users and real data show up. Making them work reliably in production is what I do. I design agentic AI systems and own the architecture decisions that decide whether they hold up: how the agents are structured, which tools they use, where the guardrails and human checkpoints sit, and how the whole thing stays observable and correct over time. I'll build where it matters — but you're hiring the judgment, not just the code. Proof, not promises: → I founded and architected työ (tyo.vaivatta.fi) — a multilingual, agentic customer- messaging platform where AI drafts and a human signs off on every message. Event-sourced core, Temporal orchestration, EU data residency, designed for the human-oversight approach the EU AI Act rewards. Launched on Product Hunt with a 5.0★ initial rating. → 20+ years architecting systems where being wrong costs money: core banking, payment and reconciliation platforms, consumer credit. That's why I lead with reliability and traceability instead of moving fast and hoping it holds. → On Upwork: Expert-Vetted (top 1%), 100% Job Success across 32 jobs and 3,700+ hours, including a year-long fractional-CTO engagement. "Seriously one of the top, if not the best freelancer I've worked with… in other websites I hired +100 freelancers, Sina is another level." Three ways to work with me: 1. AGENTIC AI ARCHITECTURE & STRATEGY — the system design, the agents, the guardrails, the evaluation loop, and a build plan your team can execute. (Or I build the critical core.) 2. AI SYSTEM RESCUE — your agent prototype works "sometimes," costs are unpredictable, or nobody can explain a wrong answer. I diagnose, stabilize, and hand back something your team can maintain. 3. FRACTIONAL CTO — an ongoing senior technical partner for the hard calls: architecture, hiring, vendor and model choices, technical due diligence. Direction without the full-time price tag. If you're not sure which one you need, book a consultation below — in 60 minutes you'll have a straight answer about what's wrong (or what to build) and what it takes, whether or not we work together. Based in Finland (EU). Native-level English. GDPR and EU AI Act are home turf, not an afterthought.
