    Dylan Buchi

    I turn messy workflows into products people can trust.

    I am an early-career full-stack developer who designs and ships focused SaaS products end to end, from interface and authentication to data, integrations, deployment, and verification.

    01 / Lead case study

    One painful workflow. One complete loop.

    CloseChase shows how I work: define the workflow, model its states and permissions, ship the complete loop, and verify what is actually ready.

    CloseChase

    A deployed product that helps bookkeeping firms collect explanations and receipt context for unclear transactions before month-end close.

    The starting point

    Unclear transactions, missing receipts, and vague client replies are scattered across inboxes. CloseChase turns that chase into one tracked request batch.

    The route through the product

    1. 01
      Create request batch

      Import or add unclear transactions for one close period.

    2. 02
      Share private link

      Generate a private client portal link, shown once, and send it through the firm’s existing channel.

    3. 03
      Collect context

      Clients answer without an account and add demo-safe receipt context.

    4. 04
      Review and close

      Approve or follow up, export close notes, then close or revoke the portal.

    How it is built

    Interface
    Next.js App Router / Vercel
    Operator access
    Clerk Organizations
    Workflow state
    Amazon DynamoDB
    Receipt binaries
    Private S3-compatible storage
    Verification
    Playwright / fake-data smoke checks

    What works now

    • Firm-scoped operator workspace and client directory
    • Batch, transaction, portal, review, activity, and export states
    • Passwordless private client portal using token-hash lookup
    • CSV import/export with formula-injection mitigation
    • Demo-safe receipt upload/download with split metadata and binaries

    Current boundary

    • Controlled fake-data pilot workflow, not ready for real customer receipt data
    • No active billing or accounting-system write-back
    • No AI/OCR or real email reminder delivery
    • Real receipt readiness still needs malware scanning, retention/deletion policy, audit logging, and legal/privacy review

    04 / Capabilities

    Capabilities

    The stack changes; the job is to connect the interface, data, permissions, integrations, and release around one useful workflow.

    Product interface

    Turn workflow states into clear, responsive surfaces with deliberate information hierarchy.

    • React
    • Next.js
    • TypeScript
    • Tailwind CSS
    • Figma implementation

    Full-stack systems

    Model the data, permissions, and server behavior needed to carry the workflow end to end.

    • Node.js
    • Python
    • DynamoDB
    • PostgreSQL
    • SQLite
    • REST APIs

    Safe integrations

    Keep organization access, private links, storage, and third-party services scoped and predictable.

    • Clerk
    • OAuth
    • Private object storage
    • CSV safety
    • Provider validation

    Verification and release

    Test the real workflow, failure paths, and deployed surface before calling it ready.

    • Playwright
    • Vitest
    • Vercel
    • Smoke checks
    • Health checks
    • Git

    05 / Principles

    How I work

    Three constraints keep the work focused and honest.

    1. Focus the workflow

      Solve one painful process completely before expanding the platform.

    2. Make limits visible

      Permissions, private links, storage, and third-party limits should be clear in both behavior and copy.

    3. Verify what ships

      Tests, browser checks, and honest product boundaries matter as much as the deployment.
