Systems delivery, software,
and acoustic engineering.
Independent technology practice based in Tallinn. I help specify, deliver, and verify software systems, AI-assisted applications, platform controls, and measurement-based acoustic work.
I'm Maksim Maškin. Over fifteen years in IT delivery and analysis — Kuehne+Nagel, ERGO, Elisa, and currently Krabu Grupp as senior IT PM and analyst.
Graduated from Estonian IT College; MSc studies at TalTech in Information Systems Analysis & Design.
EnvisiumTech OÜ is the legal vehicle for all my work — client engagements, product releases, and the audio and software R&D that runs alongside them.
I specify before I implement, measure before I conclude, and verify after delivery.
This applies across domains: a Jira workflow, an M365 tenant, a room's modal response, a two-way loudspeaker.
AI-assisted delivery is part of current practice. Iron Auditor was built solo with Claude Code and Codex. On client projects, LLM involvement varies by component — some end-to-end, some review-and-assist, some entirely human. I decide where it fits before applying it, rather than retrofitting "AI" onto existing process.

Systems Delivery & Architecture
Requirements, architecture, delivery leadership, and AI-assisted application development — where the useful output is a specified, tested, traceable system, not just generated code.
- Requirements analysis & specification
- Architecture review & trade-off documentation
- Delivery leadership & stakeholder coordination
- AI-assisted application development, verification-first
- Jira / Atlassian workflow design
Platform security & compliance
M365 hardening, Atlassian administration, and GDPR / ISO 27001 alignment for small and mid-sized organisations.
- Microsoft 365 review & hardening
- Jira / JSM / Confluence administration
- GDPR alignment
- ISO 27001 gap analysis
Room acoustics — measurement & design
Measurement-based room assessment, modal analysis, and absorber and diffuser specification. Design and specification only.
- In-room acoustic measurement
- Modal analysis & resonance ID
- Absorber & diffuser specification
- Verification measurement
A gym log that gets out of your way.
And a working experiment in agentic software engineering. Live on iOS and Android — local-first, private by design, 731 exercises built in. Built solo with Claude Code and Codex around a verification-first process: a 2,300-line spec, a 401-scenario test plan, every change traceable end to end.
