02Design × Engineering

From first idea to production.

I work on both sides of a product: the experience people see and the systems that make it work. Designing the journey and building the architecture together means fewer hand-offs, and decisions that hold up in production.

Delivery pipeline

  1. 01Design

    Discover

    Understand the users, the business and the problem worth solving.

  2. 02Design

    Design

    User journeys, interaction design and interfaces built on a consistent design system.

  3. 03Engineering

    Architect

    Data model, boundaries, permissions and APIs planned before features.

  4. 04Engineering

    Build

    Full-stack implementation — Laravel or Node.js backends, React/Next.js and Flutter clients.

  5. 05Engineering

    Deploy

    Linux servers, Nginx, Docker and cloud; release processes for web and app stores.

  6. 06Design

    Improve

    Observe real usage, fix what hurts and refine the experience.

Products in production.

Three flagship platforms — the problem, the system and my role in each. Figures are counted from the codebases.

All projects

Featured projects

MenuWav homepage showing its guest ordering, kitchen pass and menu screen workflows

01 — SaaS · Web · Mobile

MenuWave

A multi-tenant operating system for restaurants — from the till to the TV screen.

Problem
Restaurants run on disconnected tools — one for the menu, one for the till, paper tickets for the kitchen and a separate box for in-store screens. Each tool keeps its own data, so owners never see one picture of the business and every menu change is made several times.
My role
Product engineer — platform architecture, Laravel backend, admin workspace and Flutter device clients.
Engineering highlight
A global TenantScope plus role- and device-aware middleware isolate every restaurant's data across web, POS, kitchen and signage clients.

TotalCashPro homepage showing its restaurant operations dashboard for cash, staffing, attendance and weekly reports

02 — SaaS · Web · Backend

TotalCashPro

The back office for hospitality groups — cash, staff, stock, suppliers and compliance in one system.

Problem
Owners of several restaurants reconcile cash, sales, staff hours, supplier invoices and food-safety checks site by site, often on paper or spreadsheets. Numbers arrive late, rarely agree, and compliance records are hard to produce when an inspector asks.
My role
Full-stack engineer — domain modelling, Laravel backend, role-based panels and billing.
Engineering highlight
Eight role-scoped route groups (super-admin, business-admin, staff, rider, kiosk, security, API v1) over one domain model, guarded by 35 authorization policies.

ExamCell logo centered on a soft lavender background

03 — Web · AI · Enterprise

ExamCell

AI-assisted examination management for universities.

Problem
University exam offices coordinate courses, rooms, seating, invigilators, marks and results across spreadsheets and email. Every exam season repeats the same manual, error-prone work.
My role
Full-stack engineer.
Engineering highlight
Three role-specific portals over one exam lifecycle — from academic setup to published results.

Built beyond the interface.

Select a project and a layer. Every component listed was observed in the codebase; each layer says where, and whether it is implemented or planned.

Each role gets a client built for its device: a browser workspace for owners, a tablet POS, a kitchen board and a TV player.

  • Admin workspace (Blade, Tailwind, Alpine.js, Vite)
  • MenuWav POS — Flutter, Riverpod, go_router
  • MenuWav Kitchen — Flutter, GetX

08 — Engineering philosophy

Good engineering is invisible until it matters.

  1. 01

    Maintainability

    Code is read far more than it is written. Clear boundaries and boring conventions let the next engineer move fast — including future me.

  2. 02

    Performance

    Speed is a feature users feel before they can name it. Measure first, then remove work rather than add caching.

  3. 03

    Reliability

    A system is only as good as its worst Tuesday. Validation, idempotent jobs and audit trails beat heroics.

  4. 04

    Scalability

    Design for the next order of magnitude, build for today. Multi-tenancy and roles are cheaper on day one than day ninety.

  5. 05

    Product thinking

    Understand the restaurant, the exam office or the security gate before the database. The best feature is often the one you don't build.

  6. 06

    Ownership

    From the first schema to the 2 a.m. fix — I own outcomes, not tickets.

  7. 07

    User experience

    Every role in a system deserves an interface designed for its job, on the device it actually uses.
