Sasha Chepurnyi

Product & AI Engineer

I help founders and small teams design, build, and ship web apps, MVPs, AI features, and internal tools.

I'm most useful when a project is still messy — the idea exists, but the product, scope, and execution need to be shaped into something real.

What I do

  • MVPs & product builds

    From rough idea to working product: scoping, architecture, frontend, backend, integrations, and deployment.

  • AI product features

    LLM integrations, AI assistants, RAG and search, structured outputs, automations, evaluations, and reliability.

  • Web apps & internal tools

    Dashboards, admin panels, portals, APIs, and tools that help teams move faster.

  • Technical leadership

    Architecture, planning, code reviews, delivery, and small-team coordination.

How I work

  1. 01

    Clarify

    We agree on the goal, users, constraints, and what success looks like.

  2. 02

    Build

    I ship maintainable software, balancing speed and quality, with the right amount of validation along the way.

  3. 03

    Improve

    We launch, learn from real usage, and iterate.

Work

  • US-market neobankNDA

    Led a small team building a consumer neobank on top of a BaaS platform — anti-fraud integrations, sweepstakes, and customer-facing features. Owned planning, architecture, and delivery.

  • Plai

    Performance management for teams: goals, OKRs, 360 reviews, surveys, and feedback.

  • NotionSender

    Email and Notion integration with AI extraction, sending, scheduling, and automations.

  • AI & product experiments

    Prompting tools, AI-assisted workflows, automations, and small cloud-backed apps.
