Experience
Full-suite Solution for Foodics
Started as a premium dine-in add-on, pivoted into a full suite replacing the existing solution, then into a retail system outside foodtech. 13+ interconnected apps: POS, Dispatch, KDS, Driver, Invoice Printer, Customer Display, Orders Queue, Shop/Company Manager, Reporting, SuperAdmin. Built by a 10-person team over two years with my technical management, architecture, and coding of critical pieces.
38-package monorepo, around 330,000 lines of TypeScript and Vue 3, in strict layers: shared UI library and front-end and back-end data models. Core decision: mirror the data model front-to-back — every entity has an identical interface on both sides; the front end calls the matching back-end method directly with no translation layer or duplicated validation. 98% TypeScript coverage maintained quality with limited QA.
All apps run cross-platform from one Vue 3 codebase: web, Windows (Electron), and Android (WebView + Kotlin). Hardware integrations via Electron/Kotlin for printers, cash drawers, and multiscreen POS devices. Offline mode kept shops running without internet. Serverless on AWS Lambda for cost efficiency. No formal requirements: I researched the market and competitors to shape an achievable approach.

BI & Dashboards Platform for Foodics
High-performance BI and analytics platform for Saudi Arabia's largest foodtech startup. Built to process and visualize 300 million orders across multiple dimensions, a scale that made ClickHouse the only viable engine choice. Interactive dashboards with dynamic drilldowns (location, time, product, brand), deployed on AWS Lambda for cost-efficient scalability. Deployed to Foodics' customer base and contributed to measurable improvements in customer retention.
Roles: lead architect, lead engineer
Highlights:
• Sub-second queries over 300 million order records with full drilldown flexibility were solved with a ClickHouse cluster approach.
• The reporting dimensions were not clear, too varied, or changing. Built a dynamic query builder that constructs ClickHouse queries at runtime.
• The client's internal APIs had gaps and inconsistencies. I built compensating sync logic and workarounds to account for this.
• Strict multi-tenant isolation across brands, locations, and roles.
• Deployed to and actively used by around 1,000 of the client's customers with 1-100 restaurants each.

Mpenny.ai, an AI-first Engineering Platform
http://mpenny.aiMpenny is a platform and architecture for managing software development, where engineers and AI agents operate as a single workforce, with requests flowing in both directions. Each agent operates within a specific scope, and when it needs context from outside that scope, it sends a structured request to the responsible agent or to a human. The toolchain includes custom automation scripts, a review harness, and a RAG pipeline built on the project's own commit and task history, providing models with accurate project context during generation. The front end is React — a deliberate choice after years of Vue-focused client work, to stay current across both ecosystems. The platform has been built, deployed, and is in active use for my own development work.
Roles: CTO, primary engineer
Highlights:
• Several components built custom (agent orchestration, review harness) have since become available as industry-standard tooling. The platform is expected to absorb better tools as they emerge rather than focus on custom implementations.
• Built Mpenny using Mpenny itself - recreated the newer version with the solution itself, validating the core concept end-to-end.

Enterprise Command & Control Operations Platform
Enterprise Command & Control platform built as a standalone product targeting large operations centers, delivered with a 7-person team. Designed a highly configurable system with data extraction modules (SQL, REST API, CSV, API) feeding into a Data Lake. Built configurable dashboards with drilldowns and a workflow engine for internal requests and task routing. Implemented a full OrgChart with granular RBAC. Deployable on-premises or on Kubernetes, based on client needs. Built for a Saudi government client, the system was delivered as specified, but the client did not proceed to launch due to an internal strategy change.
Roles: lead architect, lead engineer
Highlights:
• The system had to be fully runtime-configurable by non-engineers: schemas, extraction flows, dashboards, and data models all set up through the UI by customers.
• Used ClickHouse and PostgreSQL as databases, allowing quick reporting if properly configured.
• Created an automated algorithm that predicts what may be required for DB index configuration and error handling in data, allowing customers to refine if needed.

Call Center Software
Fully custom call center platform supporting around 200 daily agents, processing 80,000+ calls per day (roughly 30 million per year). Replaced all third-party tools the business was running (dialer, CRM, scheduling, analytics) with a single owned platform, eliminating per-seat licensing and vendor lock-in. Implemented real-time calling using WebRTC and Asterisk, built a leads acquisition pipeline, integrated BigQuery for advanced analytics and reporting, and added configurable scheduling and workforce management.
Roles: lead architect, lead engineer
Highlights:
• Building from scratch while competing with mature commercial platforms on uptime and call quality. Got there with a solid Asterisk cluster and a WebRTC layer built to handle network degradation without losing the call.
• The system is both high-load and high-availability, achieved 99% uptime by implementing Kubernetes orchestration on AWS with dynamic Docker container scaling based on real-time user traffic.

Decentralized/Web3 Insurance Platform
Coinbase Award-winning decentralized life-insurance platform built for community mutual aid organizations. Members pool monthly contributions into a collective fund, and payments are made in the case of an unfortunate event. Implemented both smart contracts and a set of web applications for members onboarding, governance participation, and fund tracking.
Roles: lead architect, smart contract engineer
Highlights:
• Project won the Coinbase Award for innovation in decentralized insurance.
• The governance logic had to cover messy real-world scenarios (disputed claims, partial disbursements, emergency overrides) without opening new exploit paths.

Startup Collaboration Platform
Blockchain-based startup collaboration platform combining Git-based version control, issue tracker, OnlyOffice document editor, team and project marketplace, cloud storage, real-time messaging, and a payment system supporting fiat and crypto. Automated smart contract creation was a core differentiator. Authored a technical whitepaper covering architecture, tokenomics, and roadmap for investors and contributors. The platform reached production with around 600 registered users, but had to be closed after the 2018 crypto market collapse.
Roles: founder, CEO, lead architect
Highlights:
• Built and grew the engineering team from 3 to 11 people while also architecting and shipping the platform.
• Designed and deployed the DGZ token in Solidity; ran a public ICO that raised over $1M in ETH and BTC.
• Integrated on-chain payments directly into the collaboration workflow: each project founder generated a project-specific token at launch and used it to pay contributors for accepted work. Those tokens represented ownership stakes in the project. The token lifecycle (mint, assign, transfer) worked inside the Git + document + messaging workflow.
• Ran a global marketing campaign with conference appearances and a bounty program.
