Maxim K.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I help founders figure out what to build - before they spend money building it. 15 years across marketplace operations, physical goods e-commerce, and B2B software. I've launched products from zero, structured chaotic ideas into buildable roadmaps, and scaled platforms to enterprise clients like Google, McDonald's, Netflix and Samsung. On Upwork: 35+ completed projects, $300K+ earned, 11K+ hours - almost entirely product discovery, requirements structuring and pre-development consulting. Founders came to me with an idea. I turned it into user stories, scope, estimates and a plan their dev team could actually execute. I work as an individual expert. You get my experience directly. WHERE I ADD MOST VALUE Product Discovery & Scoping Structuring ambiguous ideas into clear requirements - user stories, feature breakdown, scope definition, project estimates. This is where most products fail before a single line of code is written. Marketplace Architecture Vendor models, take rate, category structure, two-sided onboarding, platform economics, OMS logic. Built for multi-vendor platforms across physical goods, services and digital products. 0→1 Product Launches From first conversation to first paying customer. Discovery, MVP scoping, GTM, customer development. Done it across e-commerce, SaaS, EdTech and service marketplaces. Physical Goods E-commerce Catalog architecture, sourcing logic, supply chain, pricing and margin management. P&L ownership across 400+ categories and 1M+ SKUs. GTM & Commercial Strategy Market entry, channel development, customer discovery, sales process. Closed $1M+ in B2B software deals with 22% cold outreach close rate - I understand both sides of the commercial equation. BEST FIT Pre-seed to Series B founders who have an idea but don't yet know exactly what to build or where to start. Or teams entering a new market or vertical who need senior product thinking without a full-time hire. Not a good fit for: execution-only tasks, teams that already have a defined spec and just need delivery managed.
