Hello, I’m PARSA MOLOUDI.
I build fast, clean, and scalable systems, from secure APIs and data pipelines to automated deployments and production observability.

01 / ABOUT
I build backend systems that stay fast, clean, and scalable.
I’m a backend engineer based in Tehran, focused on performance, clean architecture, scalability, and production reliability.
I turn complex and legacy systems into modular services with clear boundaries. My work includes multi-tenant SaaS platforms, secure REST APIs, caching, encrypted data synchronization, database optimization, automated deployments, and monitoring.
I care about the full production lifecycle: designing maintainable code, preventing race conditions, testing services, deploying without downtime, and making failures visible. I also created Homa.js, a zero-dependency TypeScript web framework built directly on Node.js native HTTP modules.
02 / CAPABILITIES
From API to production.
I design the code, data, delivery, and observability needed to keep production systems reliable.
Performance & data
Database and caching strategies that reduce load, improve response times, and remain correct under concurrency.
- PostgreSQL & MongoDB
- Redis caching
- ClickHouse logs
- Query optimization
DevOps & reliability
Automated, observable production environments with safer releases, faster incident detection, and clear recovery paths.
- Docker & Compose
- CI/CD & blue-green
- Linux & Nginx
- Sentry & monitoring

03 / SELECTED WORK
Backend systems I’ve engineered.
Production SaaS, scalable APIs, clean-architecture products, and low-level framework engineering.
Task Manager
A collaborative task platform with secure JWT authentication, role-based access, modular REST APIs, optimized data models, caching, AI-assisted workflows, and Docker-ready delivery.
Gem Panel
A multi-tenant VPN SaaS backend for managing applications, servers, configurations, and encrypted synchronization across distributed mirror servers. Refactored a critical module from roughly 2,000 lines to about 150 while adding caching, tests, monitoring, API protection, and zero-downtime delivery.
Private production system
Homa.js
A zero-dependency TypeScript framework built on Node.js native HTTP modules, with custom routing, asynchronous middleware, request-size protection, multipart and structured body parsing, query parsing, and fluent response APIs.
Jantech V2
A multilingual appliance product platform with interactive 3D presentation, rich product content, category discovery, collaboration requests, and financing flows.
ADDITIONAL ENGINEERING
Always improving.
04 / HOW I BUILD
Reliable systems need more than working code.
Keep architecture clean
Separate business rules from infrastructure so systems remain testable, understandable, and easy to change.
Measure before optimizing
Profile bottlenecks, database queries, cache behavior, and concurrency before choosing the fix.
Automate reliability
Use tests, CI/CD, monitoring, alerting, and recovery paths to make production safer by default.
