I fix that

Tech expertise for non-tech founders.
Startups and solo founders bring me AI-built prototypes, stalled MVPs, and half-finished apps - and I turn them into production software you can actually trust.

Why fractional

Benefits of hiring a fractional developer

  • Senior expertise, part-time cost

    Get years of senior engineering judgment on your product without paying a full-time salary and benefits.

  • Flexible scale up or down

    Dial the retainer up when you're shipping hard and down when things are quiet - you're never locked in.

  • Faster shipping

    An experienced developer hits the ground running, so features and fixes land in the first sprint.

  • No hiring overhead

    Skip months of recruiting, interviewing, and onboarding - I plug into your workflow from week one.

  • Embedded in your team

    I work inside your tools, standups, and codebase like a core team member, not a distant outsider.

  • Pay only for what you need

    A simple monthly retainer - no idle headcount, no wasted budget.

How it works

How does a fractional developer work

To ensure we are a perfect fit, the formal onboarding process and billing begin only after our initial discovery call.

  1. 01

    Discovery Call

    We kick off with a brief consultation to discuss your project, alignment, and goals. This is a no-obligation call to see how I can best support your business.

  2. 02

    Secure Infrastructure Onboarding

    Once we agree to move forward, you grant me secure access to your codebase and cloud infrastructure. I strictly follow industry best practices to ensure data privacy and security from day one.

  3. 03

    Codebase Audit

    I perform a deep dive into your existing repository to evaluate code quality, architecture, and technical debt, ensuring a solid foundation for future scaling.

  4. 04

    Security Assessment

    I conduct a thorough security audit to identify vulnerabilities, outdated dependencies, and potential risks in your current setup.

  5. 05

    Requirements Gathering & Refinement

    We work closely together to map out your technical needs. I clarify ambiguities and translate your business goals into precise, actionable technical requirements.

  6. 06

    Roadmap Creation

    I deliver a comprehensive project roadmap, complete with clear milestones, timelines, and deliverables, so you know exactly what to expect.

  7. 07

    Feature Development & Delivery

    I transition into full development mode, engineering robust features and delivering them in clean, well-tested, and iterative cycles.

Pricing

Simple retainers, senior expertise

Fractional developer rates are billed as a flat monthly retainer - far below the loaded cost of a full-time senior hire, with no recruiting fees, benefits, or long-term contract.
