LocalPAY — POS Integration

Remote · Bahrain

Architecting a high-performance Go-based Windows service and Laravel API layer to execute real-time, low-latency POS-to-backend data synchronization. Automating SQL Server database polling, integrating secure HMAC payload authentication, and implementing fault-tolerant retry handling alongside structured logging and custom lifecycle commands to seamlessly synchronize menus, active orders, financial transactions, and critical merchant records across distributed systems.

About

Most engineers write code that merely functions, I architect staggering digital ecosystems that scale effortlessly under immense strain and directly catalyze an astounding 80% surge in user engagement.

As a Senior Full Stack Engineer based in Lahore, Pakistan, wielding over a decade of formidable expertise in conceiving unyielding microservices and mind-bending software paradigms. I exercise an absolute, authoritative mastery over the MERN and LAMP stacks alongside AWS, seamlessly synthesizing mesmerizing user interface dynamics with uncompromising, rock-solid back-end foundations.

My repertoire centers on pioneering breathtaking AI-augmented applications driven by OpenAI APIs, autonomous agents, and LLMs. Having steered over twenty colossal enterprise deployments to triumph, notably architecting a high-concurrency ride-hailing infrastructure for the Middle East, I am profoundly devoted to sculpting fault-tolerant architectures, fluid API integrations, and elevating system throughput to truly astonishing zeniths.

Presently, I am seeking pivotal appointments as a Founding, Lead, or Senior Full Stack Developer, strategic roles wherein I may chart overarching technical trajectories, forge flagship assets, and catalyze monumental, exponential growth.

Let us convene and cultivate something genuinely extraordinary.
