Hamza Khan

Hey, I'm a backend engineer who likes making slow systems fast, fragile payments reliable, and AI pipelines actually ship.

I work across Python and Node.js on distributed, cloud-native systems. Day to day that means hunting latency, designing workflows that don't double-charge under load, and building the infrastructure behind AI products. I spent a short stretch in technical project management, then came back to hands-on engineering, because the best leadership I've seen is grounded in production scars.

About me

I'm Hamza, a backend software engineer based in Karachi, building systems that have to hold up under real traffic: auth that stays fast, payments that stay consistent, and AI pipelines that leave the request path when they should.

I've owned backends end-to-end, traced production failures before they became Black Friday disasters, and taught workshops on multimodal AI. I also briefly led delivery across five concurrent projects, then returned to the code, because I want my leadership to stay technical. Outside the stack, I share work and talks on YouTube, grow AI Baithak, and am building a research practice aimed at industrial and technical writing from Pakistan.

In my free time I love anime and writing books. I've published a novel on Webnovel and on Chereads, and I'm thinking of continuing it again soon.

Platform PitchAwesome FastAPIMongoDBRedisAWS LambdaSQSBedrockS3DockerLocustSonarQubeSentryStripe
  • Built and owned the full backend as sole engineer: a modular monolith in FastAPI covering auth, payments, workflow orchestration, and user management, serving live production traffic.
  • Reduced login latency 87.6% (1.2s → 149ms) via Motor migration, HMAC refresh tokens, and bcrypt work-factor tuning.
  • Validated under Locust: 0 failures across 500 concurrent logins (P50 180ms / P99 280ms); 0.02% aggregate failure rate system-wide.
  • Designed distributed payment workflows with MongoDB replica sets and multi-document ACID transactions, eliminating double-spend under concurrent writes.
  • Cut Docker image 750MB → 341MB (54.5%) via multi-stage builds and reduced the image’s 700+ CVEs, including 2 Critical and 40 High, to 19 fixable CVEs; only 4 Medium direct-image findings remained, with the rest inherited from the base image.
  • Reduced approximately 200 SonarQube code-quality and rule findings, after consolidating repetitive reports, to 19 actionable items; used Sentry error monitoring to keep production issues observable.
  • Built async AI pipelines (Lambda, SQS, Bedrock, S3) off the request path; resolved wallet race conditions with distributed locking.
Digitwyn

Robotics Engineer

Digitwyn · Part-time, On-site

Nov 2025 – Apr 2026 · Karachi, Pakistan

Stack Isaac SimIsaac LabDigital TwinsROS2 JazzyPhysXBlenderArduino
  • Worked on NVIDIA-driven digital twin technology: built physics-based robotics simulations in Isaac Sim as virtual counterparts of real systems, and trained agents in Isaac Lab RL environments toward manipulation goals.
  • Connected ROS2 Jazzy to Isaac Sim via Isaac ROS nodes for sensor integration and path planning within the digital twin environment.
  • Designed and built a fully in-house 2-DOF robot arm: actuator design, electrical assembly, Arduino motor control; iterating toward a 6-DOF BLDC arm.
  • Integrated software with Arduino, CNC controllers, and stepper systems; managed hardware prototyping and component sourcing.

Platform PulsR Node.jsExpressPrismaPostgreSQLGCP Cloud RunMongoDBBigQuerySentry
  • Audited an undocumented multi-system data pipeline (Retool → App Script → Cloud Run), identifying root cause of a production failure one week before Black Friday on a platform processing ~$7M in transactions.
  • Proposed and built PulsR to replace Retool ($500/mo cost & reliability risk), migrating all internal team workflows into a unified platform.
  • Designed action-oriented API endpoints across financial, campaign, wallet, coupon, and invoicing domains; integrated Secrets Manager, BigQuery, and Sentry.
  • Migrated Retool MongoDB collections; integrated Cloud Run Functions as a modular normalisation layer.
  • Built transcription pipelines for 20,000+ videos; automated coupon validation across Noon, Namshi, and Trendyol (~80% less manual QA).

Coworker Experiences

Coworker

Hamza is a hardworking and creative guy who is willing to understand the problem at heart and go the extra mile to not just solve it but prevent chained problems that may arise in the future. This way of thinking honestly made my job so much easier and the project never stumbled upon deadlines.

Rehan Hasan Project Manager @ Ovrlod
Coworker

Working with Hamza as my project manager at Sysartx was a genuine pleasure. He made collaboration easy, kept the energy high, and created an environment where the work itself was enjoyable. I would gladly work with him again.

Fahad Alam Frontend Developer @ Sysartx
Coworker

You consistently demonstrated both diligence and intelligence in your work. You strike a strong balance between working independently and collaborating effectively with the team. You show genuine curiosity and enthusiasm for learning new skills, and you pick up new concepts quickly. Your communication is clear and effective, and you interact with colleagues in a humble and respectful manner.

Research

Well-researched writing is on the way. Industrial research is thin on the ground in Pakistan, and I want to help close that gap with clear, technical, evidence-backed work.

Collaborate

Topics I want to dig into next. Open to co-authors, reviewers, and people sitting on the same questions.

Topic 01

Open Source Adoption in Industry

How companies choose, govern, and sustain open-source stacks, and what actually blocks wider adoption beyond “we should use OSS.”

Topic 02

Tourism & Technology Impact

How digital platforms, payments, and local tech infrastructure reshape travel economies: opportunities, friction, and who benefits.
