Why work with me

Business goals, engineering execution

Four principles that shape how I work with you—from discovery to direct collaboration.

360°

Strategic planning without wasted cycles

I design and ship software you can rely on — focused outcomes instead of endless feature lists.

This isn't a promise list—it's how we actually work together.

  • Business goals and scope agreed up front
  • Measurable milestones and transparent progress
  • Documented handover—no “we’ll fix it later”

Each round we refocus on your business goals. The phases below aren't a fixed template—we walk through them together until production.

From start to ship

Short cycles and real feedback until go-live.

  1. Discovery
  2. Design
  3. Build
  4. Ship

Automation where it pays off

Workflows, integrations, and alerts that remove manual drag without brittle one-off scripts.

  • Approval and status-driven workflows
  • CRM, spreadsheets, email, and custom APIs wired together
  • Scheduled and webhook-triggered runs with operational alerts

Iterative delivery

Working software early, refinements based on real usage — not waterfall surprises at the end.

Direct collaboration

You talk to the person who builds it: fast decisions, honest trade-offs, no telephone game.

Manual vs. Automated

Does this chaos look familiar?

Left: your daily reality. Right: what I build for you. Drag the slider — and decide which one you want to work in tomorrow.

Process

How do I work?

No black box: every phase has its own deliverable, and you always know where the project stands.

  1. 01

    Audit & Planning

    Week 1

    During a free consultation I assess your business processes and pain points. If custom development isn't worth it for your project, I'll tell you that honestly.

    What you get

    • Written summary of your processes and the proposed approach
    • System blueprint: modules, integrations, data flow
    • Fixed quote and timeline — no surprises later

    What I need from you

    One 60-minute conversation about your processes

  2. 02

    Prototype

    1-2 weeks

    I create visual designs and a clickable functional prototype so you can see and try the end result before development begins.

    What you get

    • Clickable prototype of the main screens
    • Finalized feature list with priorities
    • Approved design direction

    What I need from you

    Feedback on the prototype — changes are still cheap at this point

  3. 03

    Iterative Development

    2-8 weeks

    I develop in short cycles and show a working, testable version every two weeks. You follow progress in real time through the Client Portal.

    What you get

    • Bi-weekly demo with working features
    • Continuous access to the test environment
    • Transparent task and issue list in the Client Portal

    What I need from you

    15-30 minutes of feedback per demo

  4. 04

    Delivery & Support

    ongoing

    I don't let go after launch: training, documentation, and ongoing operation and development if you need it.

    What you get

    • Full source code and documentation — yours to keep
    • Training for your team
    • Monitoring and support package as needed

    What I need from you

    A decision on the support level — no obligation
