I'm Maksim Maškin.
EnvisiumTech OÜ is my independent practice, based in Tallinn — the legal vehicle for client engagements, product releases, and the audio and software R&D that runs alongside them.
Over fifteen years in IT, starting as a technical product manager at Elisa (2009–2013), where I owned identity, SMS, and voice integration products — technical enough that "product manager" and "product owner" blurred into the same role in practice. From there, system and business analysis work at ERGO Insurance, then logistics at Kuehne+Nagel, where I worked on multi-system integrations across a large enterprise environment — multi-team coordination, cross-service bug tracing, resource and ticket bureaucracy, and the constant tradeoff between compliance requirements and functional features.
More recent roles at Wisercat and currently Krabu Grupp as senior IT PM and analyst, working across Microsoft Teams, Office 365, AWS, and Grafana-based monitoring stacks. Krabu work includes Atlassian administration, Microsoft 365 security hardening, and increasingly AI-assisted delivery in components where the economics make sense.
BSc in IT from Estonian Entrepreneurship University of Applied Sciences (formerly IT College), completed while working full-time at ERGO. MSc studies at TalTech in Information Systems Analysis & Design, with thesis research on GDPR.
English, Estonian, and Russian — three languages, all at full working proficiency. Most client work is in English; Estonian for documentation and stakeholder conversations where appropriate.
A generalist by background and a specialist by inclination.
That means I'm comfortable in unfamiliar domains — acoustics, mobile development, cloud security posture, tender analysis — but I don't stay on the surface. When I commit to something, I want to understand it properly. The audio work on this site is one example: I didn't want to buy speakers, I wanted to understand driver physics, Thiele-Small parameters, enclosure alignments, and room-acoustic measurement, so I learned each of those and built things to verify the learning.
The same applies to client engagements. I read the whole RFP. I map the stakeholders before I write the specification. I push back when scope and timeline don't reconcile, and I document the reconciliation so nobody is surprised later.
Two independent threads run alongside the main practice.
Product development. Iron Auditor — a solo-built gym-logging app, live on iOS and Android — built using Claude Code and Codex across the full stack around a verification-first process. The point of the project isn't the app itself so much as the working method: what a single competent engineer can genuinely ship with current AI tooling, and where the honest limits still are.

Audio engineering. Two loudspeaker prototypes completed, a rehearsal studio designed and treated, and ongoing research into small-room acoustics. Covered in the Work section.
For engagements, advisory work, or acoustic consultations — email is the fastest route.
