Solo product · 2026

OneFeeOKR

A multi-tenant OKR platform I designed, built and launched solo: weekly email check-ins, alignment maps, a coach console, nine integrations and billing enforced in the database.

  • 23 Postgres tables isolated by 39 row-level-security policies, with 5 workspace roles and a coach mode across clients
  • Paddle billing enforced in SQL: expired or unpaid workspaces turn read-only, plan limits are triggers
  • Hourly jobs for reminders and Monday summaries; one-click email check-ins with no login

Adabra · 2024 – 2026

Stackly

At Adabra (Dubai, remote) I built the frontend of core modules of Stackly (Agency Eleva): a GrapesJS page and funnel builder with Magnus Intelligence AI generation, a template gallery, CRM reporting and the client workspace.

  • GrapesJS editor with device previews, layers, motion, inline rich-text editing, sub-pages and publishing
  • Magnus Intelligence AI in the editor: full landing pages (standard and 3D) and sections, with file and image context
  • 30+ page templates and 17 funnel step types, plus a CRM reporting suite with 10 report types (filters, metrics, five chart types)

EmpowerCRM

At Smart Engineering & Design Solutions (SEDS) I kept EmpowerCRM (empower.associates) running and growing for healthcare-staffing recruiters: fixing reported issues, shipping feature requests, and extending the Dashboard, Jobs, Sourcing and Tasks modules of an existing React SPA.

  • Shipped fixes and feature requests across Dashboard, Jobs, Sourcing and Tasks, each release visible to recruiters in an in-app changelog
  • Maintained a single-bundle React SPA used daily by healthcare-staffing recruiters managing hundreds of candidate and hospital/medical-center records
  • Made targeted changes inside an existing, tightly coupled codebase without regressing the workflows recruiters already depended on

Security Lab — Cybersecurity Simulations

Eleven of the 40+ interactive cybersecurity learning sites I built at Smart Engineering & Design Solutions: a working x86 instruction emulator, a STRIDE/PASTA threat-modeling walkthrough, a SIEM-alert triage sim and more, deployed as static pages via GitHub Pages.

  • A working x86 instruction emulator where registers, flags and the stack update live as a user steps through code
  • An interactive firewall/zone config builder and a SIEM-style alert dashboard, each turning a security concept into something you click through rather than read
  • 11 sites, zero backend or build step: plain HTML/CSS/JS deployed straight to GitHub Pages
