01 // Profile & Approach

I help companies digitalise how they work: designing and building the internal tools, automations, data pipelines, and integrations that replace manual effort and scattered spreadsheets.

My background spans solutions engineering in enterprise business software, .NET platform architecture, decoupled frontends (Vue.js, Nuxt 3, Astro), and Python and SQL data pipelines feeding Power BI.

I work end to end: from mapping the process and choosing the right platform, whether a custom build or an existing tool such as Jira, through implementation, rollout, and adoption by the team.

Wholesalers often run on estimated margins: profit is inferred from spreadsheets and manually maintained metrics instead of measured. Clarif.io gives them the actual picture of what the business earns, in one place, without the Excel layer.

  • Architected the multi-tenant platform end to end, including tenant isolation and the aggregation pipelines behind the profit metrics.
  • Engineered the backend services with .NET Web API on PostgreSQL.
  • Built the data-dense dashboards with Vue.js, Nuxt 3, and Tailwind CSS.
