/ Praveen Govind · Applications Architect

I architect systems that scale — and keep them simple.

I thrive on architecting scalable, high-performance solutions, yet simplicity is my superpower. Programming is my passion, but life is my greatest teacher. While there isn't a Wikipedia page about me (yet!), this space is here to share my journey — both in code and beyond.

01 — Selected work

Systems I've designed, shipped and run.

A few representative engagements — the problem, what was built, and what changed because of it.

01

Interactive lab

System Design Simulator

Build an architecture, send it traffic, and watch where it breaks. Then fix it within budget.

Problem
System design is usually explained with static boxes and arrows, so the trade-offs between latency, failures and cost stay abstract.
Build
A deterministic queueing model of CDN, load balancer, autoscaling servers, cache, replicas and a write queue, with a live traffic diagram and three graded challenges.
Outcome
Each challenge fails with the naive design, can't be brute-forced within budget, and needs a new idea: caching, then queues and CDNs, then scaling for launch day.

Toyota Motors North America

Enterprise Cloud Modernization

Moving long-lived enterprise applications onto cloud-native AWS and Azure platforms.

Problem
Legacy applications carried growing tech debt, rising run costs and slow, manual release cycles.
Build
Re-architected workloads into microservices and serverless components (AWS Lambda, ECS, Docker) with clear service boundaries.
Outcome
Reduced tech debt, lower operating costs and systems built to scale with the business.

Platform engineering

Infrastructure as Code & Delivery Pipelines

Every environment defined in code, every change shipped through an automated pipeline.

Problem
Hand-built environments drifted apart and deployments depended on tribal knowledge.
Build
Standardized infrastructure with Terraform and AWS CDK, wired into CI/CD automation with observability built in from day one.
Outcome
Repeatable, auditable deployments and faster feedback on system performance.

Co-founder & Technical Lead

Tech4sys Software Solutions

Co-founded a software company and built products on open-source technologies.

Problem
Clients needed dependable web applications without enterprise-sized budgets.
Build
Led development teams, designed scalable databases and delivered applications in Angular, Node.js and PHP with a strong UX/UI focus.
Outcome
Eight years of products shipped and a team grown from the ground up.

  • Node.js
  • PHP
  • MySQL
