About

From Code to Architecture

I began as a web developer - writing production code, debugging client-facing systems, and understanding what makes software reliable at scale. That foundation didn't fade; it became the lens through which I evaluate every technical decision.

My path followed a steady upward arc: in a mid-sized agency, I grew from developer to team lead - managing engineers, running estimations, and presenting solutions to clients. In a larger software company, I stepped into technical consulting - analyzing feature requirements, integrating APIs, and coordinating across QA, DevOps, and commercial teams.

Today I operate at the intersection of engineering execution and solution design - owning projects end-to-end, bridging technical and business stakeholders, and steadily expanding toward solutions architecture.

Focus

How I Create Value

I work where business intent meets technical reality - clarifying what should be built, shaping workable solutions, and staying accountable through delivery.

Role

Technical Business Analyst

Turn ambiguous goals into decisions teams can execute - with enough technical depth to keep requirements realistic.

  • Requirements that hold Capture business needs, constraints, and edge cases in language both stakeholders and engineers trust.
  • Process & stakeholder clarity Map workflows, align expectations early, and reduce rework before development starts.
  • Specs with intent Translate analysis into stories, acceptance criteria, and documentation that survive contact with delivery.
Role

Senior Technical Consultant

Guide solution shape and trade-offs with an engineering lens - then stay close enough to protect outcomes in production.

  • Solution options & trade-offs Frame architecture and integration choices against cost, risk, timeline, and operational fit.
  • Cross-team delivery ownership Coordinate engineering, QA, DevOps, and commercial stakeholders so decisions stay coherent end-to-end.
  • Presales to production Support demos, proposals, and handoff - then refine in live systems with continuous feedback.
What connects both roles
