What I Do

Product & Systems Architecture

I design scalable, reliable systems that align technology with real business and operational needs.

Technical Strategy & Backend Engineering

I architect APIs, background jobs, and data pipelines that perform under real-world load.

Web & Mobile Product Development

I build production-grade web platforms and Flutter mobile applications used by real customers.

Engineering Leadership & Consulting

I help teams make the right technical decisions early — and avoid costly mistakes later.

Selected Work & Impact

TimeTally — HR Management System

Problem: Organizations needed to replace manual, time-consuming employee performance assessments with a system that provided real-time insights and transparency.

Constraint: Needed to integrate with existing HR workflows without disrupting daily operations.

Role: Product & System Architect

Key Decisions: Designed a microservices architecture to enable independent scaling and faster iteration. Built a real-time data pipeline to surface actionable performance metrics for HR decision-making.

Outcome: Replaced manual assessment processes entirely and delivered real-time reporting capabilities that significantly improved HR team efficiency.

Ecadif POS — Multi-Branch POS System

Problem: Fragmented inventory tracking and delayed financial reporting across multiple retail outlets.

Constraint: Required real-time synchronization across 12 outlets and 2 warehouses with zero tolerance for data inconsistencies.

Role: Product & Systems Architect

Key Decisions: Designed an event-driven architecture to ensure real-time synchronization across all branches without data conflicts. Implemented comprehensive audit trails and centralized reporting to provide full financial transparency across operations.

Outcome: Improved operational efficiency by over 70% and enabled real-time financial transparency across 12 outlets and 2 warehouses.

Laterpayy — Fintech & BNPL Platform

Problem: The platform needed to handle high transaction volumes, manage lending risk, and scale with growing user base while maintaining reliability.

Constraint: Required high availability during peak transaction periods with zero tolerance for data loss.

Role: Product & Systems Architect / Engineering Lead

Key Decisions: Architected an event-driven transaction processing system to handle high-volume transactions with guaranteed consistency. Designed microservices for lending and risk assessment to enable independent scaling and maintain regulatory compliance.

Outcome: Improved transaction efficiency significantly, supported rapid revenue growth, and maintained 99.9% uptime during peak loads.

Pharst Care — Digital Healthcare Platform

Problem: Access to quality healthcare was fragmented and inefficient, with patients facing delays, limited access to doctors, and disconnected services across consultations, labs, and pharmacies.

Constraint: The platform had to operate reliably under healthcare data sensitivity requirements, real-world operational complexity, and continuous service availability expectations.

Role: Product & Systems Architect / Engineering Lead

Key Decisions: Designed a modular system architecture separating consultations, labs, pharmacy, payments, and logistics to allow independent scaling. Built secure, scalable APIs to support asynchronous workflows for lab processing, prescription fulfillment, and follow-ups.

Outcome: Launched and operated a production digital health platform supporting real consultations, diagnostics, and medication delivery. The system scaled to serve thousands of users while maintaining reliability, security, and operational continuity.
