Every building is a live site I built.

Proof, not promises.

What I build.

I turn the messy reality of business into clean, working code, and working code into outcomes you can measure.

  1. Products & Prototypes

    From fuzzy idea to production: a clickable prototype within days, so decisions get made on working software, then the full build with senior rigor across the whole stack.

    In practice: VentPro NYC, marketing site grown into a field-service platform.

    Ask about this

  2. AI & Automation

    I measure where your team's time leaks, then plug it: assistants and automations for invoicing, onboarding, and lead routing, scoped around measurable time saved.

    In practice: Cognata, where Claude grades free-text answers, with a non-AI fallback.

    Ask about this

  3. Legacy Modernization

    Incremental migrations from aging stacks and formats to fast, accessible web platforms, without breaking what already works.

    In practice: The Digital Decretals, a Word transcription turned into 1,970 cross-linked pages.

    Ask about this

  4. Web Presence & SEO

    Performance, search visibility, and local listings that compound, so you show up for the right searches in a voice that's yours.

    In practice: Spray Tanning by Rosie, a site that is a phone number, with structured data doing the selling.

    Ask about this

From first call to production.

  1. Discover

    Start with the problem.

    A short discovery sprint maps your workflows, constraints, and success metrics — then you get a fixed-scope proposal before any code is written.

  2. Prototype

    Make it tangible, fast.

    Within days you have something stakeholders can click, not a slide deck, so the direction is validated before the full build.

  3. Build

    Ship in increments.

    Working software every week, with tests, deploys, and monitoring running themselves from day one. No big-bang launch, no surprises.

  4. Launch & improve

    Measure what matters.

    Everything ships instrumented and is judged against the metrics agreed in discovery, then tuned on the evidence and handed over with docs your team can own.

I'm Moshe Malka. I've spent 18+ years building software, from scrappy startups to systems serving millions. Quentin.Code puts that experience to work for companies that need senior engineering without the cost and coordination drag of a full team.

My range covers the whole lifecycle, from product strategy through software development to process automation, so nothing gets lost between the idea and the launch.

Let's build something.

Have a product to ship, a process to automate, or a legacy system holding you back?

Tell me where you're headed. I'll map the fastest route there.
