  • 20+ storefront routes, Razorpay and COD checkout, India GST invoicing.
  • 301 redirects kept the old search rankings.
  • I reviewed 387 files before handover and fixed 5 high-severity issues, including a payment bug and an XSS hole. I still maintain it.

MY SOLAR Power: sales and P&L system

Role
Freelance developer
Since
Oct 2026
Status
Live

A 20-person sales team was logging calls, quotes and orders in a single-file prototype. I replaced it with a hosted, multi-company system with sign-in, roles, an audit log and backups.

  • Four roles enforced in both the PHP API and the database, so staff never see margins or salaries.
  • 1,000+ automated security and rule tests, and figures checked against the client's own monthly workbooks.
  • Dashboards, ratios, daily and monthly P&L, and printable reports.
  • PHP
  • PostgreSQL
  • Supabase RLS
  • JavaScript
  • GitHub CI
Private client system, so no public link.

Oct 2026
Status
Ongoing

I test shopnearn.in for Hemdip Marketing Pvt. Ltd.: an e-commerce platform with wallets, referral payouts and two Play Store apps.

  • A written test plan, then testing on the live site with write requests blocked, so no real data could change.
  • 58 admin screens tested button by button. 60 defects logged with severity, evidence and an owner.
  • Found why wallet orders were being auto-cancelled, audited a 372-product catalogue and matched stock to paper registers.
  • Test planning
  • Defect triage
  • Regression
  • Security checks

05About

I like things that work when real people use them.

I'm Aryan, a full-stack engineer from Ahmedabad. I learned most of what I know by shipping: a marketplace I co-founded, a client's online store and an internal business system, each with real users and real money moving through it.

I care about the parts nobody sees: a clean data model, honest error messages, a checkout that doesn't lose someone's cart. I work across the whole stack, from the interface and API to the database, payments and monitoring.

I also do QA, part-time. Finding other people's bugs, politely and with evidence, makes me better at preventing my own.
