My Story
I'm Hassan, a Full Stack Engineer and Team Lead who builds production-hardened systems that hold under real pressure.
I wrote my first lines of code at 14 in GW-BASIC — driven by curiosity and a need to understand how things worked. That curiosity evolved through C++ in college, Java at university, and eventually into a full-stack career building systems that handle real users, real transactions, and real operational complexity.
My stack has never stayed still — and that's deliberate. TypeScript and Node.js built my foundation, then came distributed systems, Kubernetes, and smart contract integration. Right now I'm going deep on Go (Golang) for performance-critical services, while my primary focus shifts toward AI Engineering — specifically autonomous agents, agentic workflows, and production-ready RAG pipelines.
If you're building something that needs to perform under pressure and last beyond the first release, that's the kind of problem I enjoy solving.
Tools evolve quickly, but engineering judgment compounds over time. I value systems that remain understandable, maintainable, and resilient long after the first release.
How software behaves under load, inside containers, or across distributed systems shapes how I approach architecture from the start. Infrastructure is part of the product, not an afterthought.
I believe strong technical leadership stays close to the work. I contribute to architecture, mentor engineers, and keep shipping — because good decisions come from context, not distance.
Full Stack Engineer & Team Lead
Blockrithms- Own end-to-end development and production operations across fintech, proptech, and marketplace systems, spanning architecture, Dockerized deployments, CI/CD pipelines, and live incident resolution.
- Architected a microservices-driven game marketplace orchestrating multi-stage payment pipelines with smart-contract workflows, idempotent cashback logic, and a fault-tolerant job system (BullMQ/Redis) with dead-letter queues and configurable retry policies.
- Engineered a custom blockchain indexer optimized for minimal RPC cost, achieving 99.999% (five-nines) event-delivery reliability.
- Designed a high-volume data ingestion engine processing 60,000+ external API calls daily using rotating proxy pools and queue-based throttling to eliminate rate-limiting bottlenecks.
- Diagnosed and resolved a critical Zombie Worker socket hang in production — implemented manual worker termination logic to restore system stability under live load.
- Built and operated a crypto-to-fiat cards platform (500–1,000 active users) executing real cross-border transactions, integrating smart contracts for automated payment execution and recharge workflows.
- Co-architected a multi-tenant real estate SaaS with geo-aware property discovery, Stripe-integrated freemium billing, and an AI-assisted listing tool supporting up to 500 units per property.
- Lead and mentor junior developers through structured code reviews, enforcing production-grade standards across the full TypeScript/NestJS/Next.js stack.
Full Stack Engineer
Confidential Client (Contract)- Collaborated directly with client engineering leadership on system architecture, API design, and scaling strategy for high-throughput crypto payment systems.
- Eliminated vendor lock-in on a production fintech platform whose entire codebase, schemas, and routes were tightly coupled to a single backend provider, re-architected the integration layer to onboard a second provider as a drop-in replacement with zero disruption to existing functionality.
- Built a multi-tenant crypto payment gateway from scratch, enabling businesses to onboard, manage merchants, and accept payments via APIs, QR flows, and webhooks.
- Delivered a pixel-perfect frontend for a crypto card platform, integrating smart contract interactions via thirdweb SDK to enable seamless on-chain user flows.
- Engineered secure payments infrastructure including API key management, webhook protection, key rotation, and a custodial flow for crypto settlements and payouts.
- Refactored a fragile smart contract integration by introducing wallet integrations (wagmi, MetaMask, Coinbase), significantly improving reliability and UX.
Frontend Developer
Tecno Sphere- Translated complex Figma designs into pixel-perfect, responsive interfaces across multiple client projects spanning e-commerce, service, and business domains.
- Achieved 100/100 Lighthouse Core Web Vitals across all client deliverables through aggressive performance optimization — code splitting, lazy loading, prefetching, and optimistic UI.
- Developed interactive, animation-driven interfaces using Framer Motion and GSAP — implementing scroll-based transitions, micro-interactions, and layout animations to production standard.
Freelance Web Developer
Self-Employed (via Referral)- Delivered projects for clients across various industries while completing a full-time degree — building production UI work from the earliest semesters of university.
- Developed responsive, cross-browser web interfaces using HTML, CSS, Bootstrap, and JavaScript for small businesses sourced through a peer referral network.
- Managed full project lifecycle independently — requirements gathering, implementation, revisions, and delivery — without direct client-agency overhead.
B.Sc. Information Technology
University of the Punjab (PUCIT)- Studied software engineering principles, data structures, algorithms, database systems, and computer networks.
- Applied coursework directly to freelance and professional projects from semester 4 onward — graduating with 3+ years of practical engineering experience alongside the degree.
Intermediate — Computer Science (ICS)
National Science College- Studied Mathematics, Physics, and Computer Science — building the analytical foundation that led directly into an IT degree.
- First formal exposure to programming fundamentals, logic building, and computational thinking.
Matriculation — Computer Science
Allied School- Elected Computer Science as a core subject at secondary level — an early and deliberate choice toward a career in software.
Extensible CLI for scaffolding production-ready Express.js APIs with support for TypeScript/JavaScript, multiple databases (MongoDB, PostgreSQL), plugin-based architecture, and built-in code generators. Ships with authentication, RBAC, validation, logging, and Docker setup out of the box.
Production-ready NestJS scaffolding tool that bootstraps scalable backend services with a clean modular architecture, preconfigured tooling, and best practices for rapid development.
Node.js CLI utility to detect and auto-patch critical React and Next.js vulnerabilities (CVE-2025-55182) across local projects and GitHub organizations. Designed for bulk auditing and secure dependency remediation workflows.
