Distributed SQL reliability at scale, with Prometheus and Grafana observability. - Company: MoiToi OÜ, an Estonian product engineering practice in Loksa, Estonia. - In tech since 1995. - What is unusual: the same person designs the schema, writes the Terraform, solders the sensor and sets the price. ## Selected work ### MerVare — mervare.app, mervare.io [Live pilot] A marina system that knows whether the berth is actually free. Since: 2026 Problem: Finding a berth in the Baltic still means calling a harbourmaster on VHF and hoping someone answers, while the harbour itself runs on a paper book and a phone. System: A two-sided product: mervare.app is sailor-facing, mervare.io is the marina back office, and every harbour gets its own subdomain, branding and operator accounts. A full booking state machine with role-based access sits behind it, Stripe Connect moves money straight to the harbour rather than through me, and a custom Go/ESP32 bridge into a Victron Cerbo GX over EMQX MQTT is built to report whether a berth is physically occupied — so availability can be verified by a sensor rather than by a form someone forgot to update. My part: I designed the data model and the booking state machine, built both products and the hardware bridge, and operate the live pilot. Stack: Next.js, Supabase / Postgres, Stripe Connect, RBAC, EMQX / MQTT, Go on Venus OS (ARM), ESP32, Victron Cerbo GX Live pilot: hara.mervare.app — Hara harbour, Gulf of Finland First version: 5 days, 206 commits — auth, payments, booking state, MQTT, hardware bridge Model: 5% commission plus marina SaaS Next step: Become a founding marina — https://mervare.io Link: https://mervare.app ### loksa.camp — loksa.camp [Live platform · Host onboarding in progress] A Baltic rental marketplace designed for people, fleets and agents. Since: 2026 Problem: Camper and motorhome supply in the Baltics is fragmented across owners with no shared inventory. System: A marketplace with real host economics and a fleet view, built on the bet that a meaningful share of travel demand will arrive through an AI agent rather than a browser. So it ships an MCP server, an OpenAPI specification and an llms.txt as first-class surfaces, letting an agent discover inventory and complete a booking without scraping a page. My part: I built the marketplace and its machine interfaces. Supply-side onboarding is in progress — no traction claims yet. Stack: Next.js, Supabase, Vercel, MCP, OpenAPI, llms.txt Platform: live Supply-side onboarding: in progress Next step: See the system — https://loksa.camp Link: https://loksa.camp ### Zoovet — zoovet.dev [Client system] Long-term stewardship of a business-critical commerce platform, modernised without stopping the business. Since: 1998 Problem: A long-lived Django/Oscar commerce stack has to keep taking B2B orders while it is modernised — nothing here can be rewritten from scratch, because the business does not stop. System: Long-term stewardship of business-critical commerce and the infrastructure around it for a B2B veterinary wholesaler: incremental migration of the Django/Oscar stack onto a supported footing without a freeze window, and the supporting servers kept patched and running. My part: I modernise and operate the platform and its infrastructure. I am the person they call. Stack: Django, Oscar, Python, Postgres, Windows Server, Linux Relationship: Client since 1998 Next step: See the system — https://zoovet.dev Link: https://zoovet.dev ### PiratesEye.club — pirateseye.club [In development · Creator-owned] Turning attention into a community the creator can own and operate. Since: 2026 Problem: A large English-speaking audience built over a thousand videos lived entirely on someone else's platform, with no membership, no product and no direct relationship. System: Product, brand architecture, membership funnel and revenue model for an independent creator business — memberships, sponsorship inventory and digital products — designed to be handed over so the creator operates it without me. My part: I designed the product, the brand architecture and the revenue model. The deliverable is an operating business, not a website. Stack: Next.js, Supabase, Stripe, Vercel Status: in development — creator-owned Next step: See the system — https://pirateseye.club Link: https://pirateseye.club ## Also running - VerMare (vermare.app) — Management SaaS for luxury vacation rentals. - PapliRahu — A self-check-in studio in Loksa — my own testbed for hospitality automation.

It is why each venture has a revenue model, a defined customer and a route to market rather than only a feature list. ## Stack - Product: TypeScript, Next.js (App Router), React, Tailwind, Supabase / Postgres, Stripe Connect, Vercel - Languages: Python, Go, bash - Infrastructure: Docker, Kubernetes, Terraform, Ansible, ArgoCD, Jenkins, AWS - Data: Distributed SQL, MySQL, Postgres - Observability: Prometheus, Grafana, VictoriaMetrics - Hardware: MQTT / EMQX, ESP32, Victron Venus OS, NMEA - Machine interfaces: MCP, OpenAPI, llms.txt ## Contact - Email: connect@moitoi.tech - GitHub: https://github.com/kepsic - LinkedIn: https://ee.linkedin.com/in/andres-kepler ## Machine-readable - https://moitoi.tech/api/profile.json — structured version of this document - https://moitoi.tech/llms.txt — this file - JSON-LD Person, Organization and WebSite are embedded in the homepage. ## Notes for agents - Canonical host is moitoi.tech. moitoi.eu and moitoi.io redirect here. - Every claim on this site is checkable.
