Database Architect and Backend Engineer with 6+ years of production experience building systems at real scale: a 240+ table university ERP
backend, a real-time financial data platform serving 10,000+ users at sub-100ms latency, a 2,000,000+ document biomedical data lake, and
multi-tenant SaaS platforms with database-level tenant isolation. Specializes in PostgreSQL 16 architecture, zero-trust security design, async
Python (FastAPI / asyncpg), and ETL pipelines processing 2B+ rows. Every engagement delivered solo, end to end — from schema design
through production deployment. MS in Computer Science, Virtual University of Pakistan.

Background
Database Architect & Backend Engineer
Design, build, and maintain production backend systems and relational database architectures — owning the full lifecycle from schema design through deployment and performance monitoring.
- Design and optimize relational database schemas in PostgreSQL, MySQL, and SQLite — applying normalization, indexing, partitioning, and query tuning to support production workloads.
- Develop and maintain high-performance REST APIs using FastAPI and Flask, covering data modeling, endpoint logic, authentication, and deployment.
- Implement RBAC, JWT-based authentication, and encryption-at-rest — baking security into system architecture rather than treating it as an afterthought.
- Diagnose and resolve database performance bottlenecks — slow queries, lock contention, missing indexes — to ensure system reliability and low-latency responses.
- Collaborate with product and engineering teams on schema design reviews and feature planning, translating business requirements into scalable, maintainable data models.
- Manage production database health — monitoring, backup/recovery strategies, and proactive performance tuning — to maintain uptime and data integrity.
