Hire me

Principal Software Engineer with over 7 years of experience designing scalable, cost-efficient architectures using TypeScript, Rust, and AWS serverless technologies. He has a proven track record of building mission-critical financial systems, high-performance recommendation engines, and custom developer platforms that optimize production speed and system reliability.

Experience

Senior Full Stack Engineer / Solution Architect

Office FieldKarachiworkJul 2025 – Aug 2026

Built V2 of the core product on Astro using an SDK-based micro-frontend approach: each page is a separate repo published to npm and loaded into an app shell that delivers an optimized SSR application. Designed a recommendation engine that serves preference-based, pre-scored feeds in milliseconds with minimal resource use, using NATS and WebSockets. Built a real-time price tracker and search backend handling thousands of requests per second, pushing live price updates to the frontend efficiently. Developed custom MCP servers and AI-driven tooling that automate backend workflows and shorten time to production. Architected a modular internal platform and shared SDK ecosystem (auth, distributed jobs, caching, observability) using transactional outboxes, circuit breakers and idempotent processing. Created the Enigma CLI to automate service scaffolding, OpenAPI generation and health diagnostics, enforcing consistent, production-ready service structure across squads.

Summary

Owned solution architecture for mission-critical financial backend services, balancing sub-millisecond latency, high availability and infrastructure cost. Built reusable serverless modules with AWS CDK, Lambda, CloudFormation and CloudWatch to standardize infrastructure across projects. Created SDKs and code automation for one-click application setup and deployment. Designed a custom query language that lets frontends fetch data dynamically by parameters. Built a CRUD generator that auto-creates resource routes, restricts fields and applies privacy rules, cutting the work needed to ship new APIs. Ran deep database query optimizations and event-driven designs that enabled horizontal scale and lower infrastructure cost. Standardized service primitives, quality and security practices across distributed teams to prevent technical debt.

What I did

Optimized performance by shifting business-logic-independent actions to a Rust FFI layer using CString to avoid encoding/decoding overhead in Bun.
Implemented a benchmark gate to select the most efficient execution path between Rust FFI and raw JavaScript.
Created reusable modules that function like microservices to assemble applications with minimal effort.

Results

Authored private, organization-funded formal technical deep-dives and architectural documentation.
Developed AI-driven SDKs and custom frameworks to automate SaaS application creation using reusable, modular components.
Delivered SaaS applications in a few weeks with a team of 3 engineers.
