Deep dive into your business logic, system bottlenecks, database entities, and third-party API dependencies. Crafting a rock-solid technical blueprint.
Rapid iterative development with clean code principles. Weekly progress demos, staging sandbox deployments, and transparent asynchronous updates.
CEH-informed penetration audits, SQL injection prevention, PostgreSQL query optimization, and UI responsiveness testing across mobile and desktop.
Production deployment on AWS / Nginx, zero-downtime data migration, automated daily backup crons, and ongoing post-launch operational support.
A curated toolkit refined through 5+ years of production engineering and problem solving.
Direct feedback from international & Pakistani enterprise founders who scaled their operations, ERPs, and revenue with my engineering.
“Haroon solved our multi-warehouse inventory desync between 3 UK depots and Shopify in less than 48 hours. The custom Odoo 17 connector he wrote eliminated overselling entirely and automated our courier dispatches.”
“Our real-time task workspace was lagging under 5,000 concurrent websocket connections. Haroon stepped in as senior architect, optimized our Flask backend, and re-indexed our PostgreSQL schemas — latency dropped from 850ms to 42ms.”
“Internet disconnects used to freeze our retail branch counters. Haroon built an offline-first POS system with instant thermal receipt printing and auto-sync that keeps all 4 of our branches operating with zero interruption.”
“Haroon fixed our broken iOS 14+ ad tracking with a robust Server-Side Meta Conversions API setup. Our attribution clarity skyrocketed immediately, helping us scale our ad spend safely and reach a 4.3x blended ROAS.”
