Enterprise CRM - Sales Pipeline & Performance System

Designed and shipped a custom CRM that turned fragmented sales tracking and reporting into one shared operating workflow.

Lead Full-Stack Engineer 6-week delivery sprint Remote contract delivery
  • Problem

    Pipeline updates and performance reporting were split across 3 separate spreadsheets, making weekly reviews take days and ownership hard to trust.

  • My scope

    Mapped sales stages, reporting rules, and operator roles before touching schema or UI.

  • Result

    Cut the weekly pipeline review cycle from ~2 days of spreadsheet reconciliation to ~15 minutes — single source of truth across sales, ops, and management.

Problem

Pipeline updates and performance reporting were split across 3 separate spreadsheets, making weekly reviews take days and ownership hard to trust.

Constraints

  • Had to fit active sales operations with minimal disruption
  • Needed role-based access for contributors and managers
  • Deployment target required Docker + Nginx with predictable recovery

Delivery

  • Mapped sales stages, reporting rules, and operator roles before touching schema or UI.
  • Built Laravel + PostgreSQL services for pipeline events, rollups, and role-based access.
  • Implemented a focused Next.js operator interface for updates, reviews, and manager visibility.
  • Delivered Docker + Nginx deployment structure so the handoff was stable and recoverable.

Result

  • Replaced 3-spreadsheet sprawl with one shared CRM — pipeline review cycle cut from ~2 days to ~15 minutes.
  • Removed all manual reconciliation from weekly reviews; ops lead recovered an estimated 6+ hours/week.
  • Role-based access, proposal PDF generation, and pricing engine shipped — operator returned for a 2nd engagement in a different vertical.

Automation Systems

Client delivery

Inbound Order & Lead Ops Automation

Automation Engineer2-week delivery sprint

Eliminated an estimated 60–80 hours/month of manual data entry across multi-branch operations. Booking + reporting now flow automatically into a single source of truth.

  • Problem

    Inbound orders, bookings, and chat updates were copied manually into spreadsheets across multiple branches, producing inconsistent records, delayed follow-up, and zero operational visibility for management.

  • My scope

    Implemented web-order-to-sheet automation with validation and normalization.

  • Result

    Eliminated an estimated 60–80 hours/month of manual data entry across multi-branch operations. Booking + reporting now flow automatically into a single source of truth.

Multi-Surface Platform Monorepo

Monorepo Platform Engineer4-week delivery sprint

Reduced release friction and dependency drift across the platform.

  • Problem

    Separate repositories for related surfaces caused dependency drift and slowed coordinated releases.

  • My scope

    Structured the repository with npm workspaces and clearer package boundaries.

  • Result

    Reduced release friction and dependency drift across the platform.

  • npm workspaces
  • Next.js
  • NestJS

Android + AI

Media Android App - AI Chat + Search UX

Android AI UX Engineer3-week delivery sprint

Stabilized AI chat-to-search state sync in production — eliminated mismatch issues that broke the discovery flow for end users.

  • Problem

    Users lacked a clear transition from AI chat prompts to meaningful search actions, and state sync issues reduced UX reliability.

  • My scope

    Worked inside the existing WebView-based AI entry path so the feature fit the live app architecture.

  • Result

    Stabilized AI chat-to-search state sync in production — eliminated mismatch issues that broke the discovery flow for end users.

  • Kotlin
  • WebView
