What gets built

Six things, done in-house.

Websites, internal tools, AI, automation, booking and payments — design through deployment, all from one small studio. Built once, owned by you, no monthly SaaS.

For businesses that want to own their stack

One package, end-to-end. Built once, yours to keep.

A complete website with an editable CMS, online booking and payments, and self-hosted infrastructure that doubles as your admin panel — built end-to-end and owned by you. No monthly SaaS fees, no platform lock-in.

  • Multilingual Marketing Site

    Multiple languages with automatic browser detection. Hero, highlights, gallery, services, FAQ, and contact — all editable from the CMS.

  • Booking & Ticketing Flow

    Multi-step booking with date picker, time slots, guest counts, add-ons, and confirmation with calendar .ics download and reference numbers.

  • Self-Hosted CMS & Admin Panel

    Payload CMS as the admin panel and lightweight CRM. Manage events, bookings, tickets, and site content — no code required, no monthly fees.

For businesses ready to automate

AI agents and automation, built for the way you work.

Custom AI agents, workflow automation, and integrations between your existing tools — built end-to-end and owned by you. The boring middleware and the smart layer, shipped together by one studio.

  • Workflow agents that take work off your team

    Multi-step agents that read your inbox, your CRM, your ticketing system — and act. Not chatbots: working colleagues that ship outcomes.

  • RAG pipelines on your own data

    Knowledge agents that answer questions from your docs, contracts, and product manuals — with citations. Self-hosted; your data never leaves.

  • Integrations and middleware that just work

    Quiet pipelines between the tools you already use — booking systems, CRMs, accounting, calendars. The plumbing nobody wants to build.

The process

Four phases, no surprises.

A predictable rhythm from kickoff to launch. Progress shows every week, not just at the end.

  1. Discovery

    The business, users and technical lay of the land get a deep look before any code. You leave this phase with a written brief and a defensible plan.

  2. Design

    Wireframes → high-fidelity design → clickable prototype. The experience and design system get validated before development picks them up.

  3. Development

    Weekly demos in agile sprints. Clean TypeScript, automated tests, code reviews. Deployed on every push — you can poke at it any time.

  4. Launch

    Production deploy with monitoring, error tracking and a clear rollback plan. Support stays on for the first weeks, with iteration driven by real usage.

    2026 · AI call analysis & sales pipeline

    CallIQ

    Internal AI pipeline for a sales team. Every call from the phone system is transcribed speaker by speaker, then scored 1–10 and tagged for sentiment and category by OpenAI. The results flow straight into the deal pipeline — stages, next actions and loss reasons update themselves, so managers read the funnel instead of listening to recordings. Hermes and Claude agents are connected to the database and can give deep insights. Connected Meta and Google API gives even more detail about marketing campaigns and the lead origin.

Client feedback

What clients say once it's live.

Short, honest notes from the people whose products I've shipped — launch websites, browser tools and AI work alike.

  • Fantastic! Thank you for the complete overhaul and all your support during the deployment. The new site is exactly what we needed. Great job!

  • PumpWork is honestly on another level! Unlike other clunky plugins and services, the functionality here is incredibly well-thought-out. It's super intuitive, fast, and does exactly what you need without any bloat. A genuinely cool and useful tool!

    PumpWork user

  • We came to Andriy with a rough pitch and a tight deadline, and got back a site that actually sells — sharp positioning, a free-reel funnel that converts, and a subscription flow that just works. We had our first paying sign-ups the week we launched.
