Hi,
I'm Harsh Dev
Full Stack Developer

About

I am a Full Stack Developer with over 2 years of hands-on experience engineering production systems. I specialize in building complex, data-intensive applications, having recently delivered a maritime routing engine that achieves ~95% accuracy against real-world shipping routes, and a zero-dependency Excel engine featuring topological dependency resolution.

I thrive on end-to-end ownership. From architecting scalable database schemas in PostgreSQL and migrating legacy services, to designing asynchronous job pipelines with BullMQ, I take systems from concept to deployment. My work with spatial indexing (PostGIS, H3) to route ships efficiently demonstrates my ability to tackle niche, high-complexity domains.

On the frontend, I craft highly responsive and SEO-optimized interfaces using React.js and Next.js. I am deeply focused on performance; for instance, I recently architected an IndexedDB caching layer that reduced client load times by ~50% for a ~22,000-record geospatial dataset.

My infrastructure expertise spans Docker, CI/CD pipelines via GitHub Actions, and managing bare-metal KVM servers. I actively maintain self-hosted applications like Easy Budget and Pastebin Lite, and contribute to the developer ecosystem with open-source NPM packages like http-reply.

Whether it's optimizing a database query, designing a REST API, or configuring a reverse proxy, I am comfortable across the entire stack—delivering reliable, scalable, and business-driven solutions.

Where I'm currently working

Full Stack Developer

Viexports·Sept 2024 – Present·New Delhi
  • Architected and delivered a backend automation system (Node.js, Express, cron) that automated daily backups, email triggers, and complex freight calculations, successfully replacing manual processes and accelerating operational cadence from 2–3 times weekly to daily.
  • Developed a zero-dependency custom Excel-like computation engine from scratch, implementing a regex-based tokenizer and a dependency graph utilizing topological sort for precise, stale-free recalculation across 300+ rows × 20 columns of interdependent financial data.
  • Spearheaded core architectural decisions in collaboration with company leadership, including database schema design and the adoption of BullMQ for asynchronous job queuing. Successfully owned the end-to-end migration of the routing service from Python to Node.js.
