Go Developer & Backend Engineer — Pakistan
I'm a Go developer from Pakistan, obsessed with the internals of high-performance server systems. Right now I'm mastering what it takes to architect backends that can handle 50,000+ requests per second — studying concurrency patterns, connection pooling, load balancing, and profiling under real load.
My work lives at the backend layer: REST APIs, concurrent data pipelines, CLI tooling, and clean service architecture. I use Go, PostgreSQL, and patterns from the clean architecture school — keeping logic separate from transport and infrastructure.
Beyond APIs, I build tools that automate the boring parts of development — a TUI-based code scaffolding tool, an automatic project structurer, and a concurrent web scraper. I believe a good developer should be able to build the tools they use every day.
I write about what I learn: backend design, Go internals, performance engineering, and the craft of building things properly.
Currently
- Mastering server performance engineering — targeting 50k RPS architectures
- Designing backend systems with clean architecture in Go
- Building real tools: scaffolding TUI, project structurer, web scraper
- Open to backend engineering roles and collaboration
About
I'm based in Pakistan and work entirely on the backend. I picked Go because of its simplicity, speed, and suitability for building concurrent, high-throughput systems. Go's approach to concurrency — goroutines and channels — maps naturally to how I think about distributed server architecture.
I completed a comprehensive Go course and immediately went deep: building production-style backends, studying how databases handle load, how HTTP servers manage connections, and what actually makes a service fast under pressure. I care about doing things right — idiomatic code, well-modelled domains, testable design.
When I'm not writing Go, I'm reading about distributed systems, studying open-source codebases, and writing about what I find. I believe the best engineers never stop being students.

Projects
Dropstyle Reservation Engine
A highly-concurrent ticket reservation system architected to solve distributed state problems. It uses advanced goroutine synchronization to manage parallel booking requests, implement precise seat locking mechanisms, and guarantee ACID transactional integrity under dynamic load conditions. The system includes a robust REST API for handling concurrent user sessions, inventory management, and real-time seat availability updates while preventing race conditions.
Decoupled E-commerce API
A scalable, production-grade e-commerce backend system built with Go and PostgreSQL. It employs strict Domain-Driven Design (DDD) and clean architecture principles to thoroughly decouple transport layers, business logic, and data persistence. The platform features comprehensive product catalog management, a secure shopping cart subsystem, asynchronous order processing, and role-based access control using JWT authentication.
High-Throughput Web Scraper
A robust, high-throughput data extraction engine utilizing Go concurrency patterns. It implements dynamic worker pools to gracefully manage system resources, respect rate limits, and orchestrate parallelized data pipelines for reliable serialization. The pipeline is designed to organically extract structured data from multiple disparate sources simultaneously, export the normalized results to CSV and JSON formats, and handle network failures with exponential backoff strategies.
Gen Code Scaffolding TUI
A developer productivity tool featuring a rich Terminal User Interface (TUI) for intelligent project scaffolding. It uses the Bubble Tea framework's Elm architecture to cleanly manage complex terminal state and generate opinionated, robust project structures. The tool allows developers to interactively select their target language and framework, automatically generating appropriate directory layouts, configuration files, and modular entry points.
Core Banking Ledger Engine
A pure-Go core banking ledger system designed to solidify foundational system architecture concepts. It features strict state mutation controls, immutable transaction histories, and interface-driven design to ensure accurate financial data handling and a clean separation of concerns. The ledger supports distributed user accounts, secure concurrent deposits and withdrawals, and complete audit trails for every transaction executed within the system.
