Product Engineering
Web applications, sites, and APIs built with modern frameworks and boring, reliable architecture. We optimise for maintainability and speed in production, not novelty in demos.
Mejesco LtdEuropean digital agency
Software and marketing, built to last.
Mejesco is a European digital agency that designs, builds, and grows web products for companies that treat their online presence as core infrastructure — not an afterthought.
About
A small team with a long attention span
Mejesco is a software development and digital marketing agency. We build web products end to end — strategy, design, engineering, and the marketing that makes them perform — for clients across Europe who need a partner, not a vendor.
We deliberately stay small and senior. Every engagement is handled by people who have shipped production systems and run real campaigns, not handed down a chain. That means fewer meetings, faster decisions, and work that doesn't need to be redone in a year.
Most of our client relationships are measured in years, not projects. We prefer it that way: the best results come from teams that know a product deeply, own their decisions over time, and are still there when the roadmap changes.
What we do
Full-stack, in the honest sense
From first commit to first customer — and every release after.
Brand & Identity
Naming, visual identity, and design systems that survive contact with real products. Everything we design ships as reusable components, not a PDF that gathers dust.
Growth & Performance Marketing
Paid acquisition, SEO, and conversion optimisation run against clear unit economics. We report on outcomes — cost per acquisition, retention, revenue — not impressions.
Data & Analytics
Measurement architecture, dashboards, and attribution you can actually trust. We instrument products properly from day one so decisions rest on data, not opinion.
Cloud & Infrastructure
Deployment, scaling, monitoring, and security on modern cloud platforms. Fast globally, resilient under load, and priced sanely — infrastructure as a quiet advantage.
Ongoing Partnership
Retained teams for products that keep evolving. Roadmap planning, iteration, and support from the same people who built the thing — continuity as a feature.
How we work
Four steps. No theatre
Discover
We start with your business model, your users, and your constraints — and put a written, scoped plan on the table before anything gets built.
Design
Interfaces and architecture take shape together, prototyped early and tested against real content and real data, so surprises happen on screens, not in production.
Build
Senior engineers ship in short, reviewable increments with automated testing and staging environments — you see working software weekly, not a reveal at the end.
Grow
After launch we measure, optimise, and market: performance tuning, conversion work, and acquisition campaigns that compound instead of resetting every quarter.
Technologies
A deliberate stack
We standardise on proven, well-supported tools — chosen for longevity and hiring depth, not fashion.

What we build
The shapes of work we do best
01
High-traffic content platforms
Editorial and content-driven sites engineered for scale: statically rendered where possible, cached aggressively at the edge, and structured for search from the schema up. Built to hold sub-second loads and stable Core Web Vitals at millions of monthly pageviews.
02
Conversion-focused commerce & funnels
Landing pages, checkout flows, and onboarding journeys where every step is instrumented and every change is measured. We run structured A/B testing against revenue metrics, so design debates end with data.
03
Internal tools & dashboards
Admin panels, reporting suites, and operational tooling that turn scattered spreadsheets into a single source of truth. Role-based access, audit trails, and live data pipelines — built so teams actually use them.
