How I work remotely
No timezone tax.
I've delivered remotely for teams in Georgia (US), Australia, Japan and the UK from an IST base — four hours with US East, a full day with EU and APAC.
Overlap, not silence
Standups, reviews and pairing inside your working day. Six years of it across US, UK, Australian and Japanese teams.
Written by default
Decisions land in the PR, the ticket or a short doc — so the team keeps moving while I am offline.
Your tools, your process
Slack, Jira, Linear, GitHub, whatever you run. I adopt the workflow instead of importing mine.
Handover is the deliverable
Pipelines, dashboards and runbooks documented, so nothing depends on me staying.
Engagement terms
Hire me for
a sprint or
a quarter.
Contract, retainer or fractional lead — invoiced monthly, NDA and MSA on request, paid by wire or Wise. Fixed scope where the work is well defined, hourly where it isn't yet.
