Ahmed Khalid · Tech Lead and Full-Stack Developer
I engineer software,
and lead the people who build it.
Fifteen years across distributed systems, database performance, and leading teams that know how to deliver.
What I build
Five areas my work keeps returning to, from breaking monoliths apart to making queries fast and hardening what reaches production.
Distributed systems
Breaking monoliths into services with boundaries that isolate failure and let deploys move faster instead of stalling.
10M+
Database performance
Query optimisation and schema redesign on tables past ten million rows.
Cloud infrastructure
AWS (RDS, EKS), Docker containers, infrastructure as code, and automated delivery pipelines.
Application security
Vulnerability assessment, system hardening, and code review, before a flaw ever reaches a user.
Engineering leadership
Growth plans for developers, technical roadmaps, and structured mentoring that lifts the team rather than a few individuals.
The tools I work with
Proven in production rather than in side projects, chosen because they last.
Backend and data
Services and REST APIs, query optimisation, and schema design.
Frontend
Web and mobile interfaces built to be maintained, not rewritten every year.
Operations and cloud
Infrastructure as code, automated pipelines, and hardening for what runs in production.
Have a system that needs a steady hand?
I am open to conversations about engineering leadership, database performance work, and restructuring systems already in production.
