I build and ship production web platforms end-to-end
One year as the sole developer on two live products — a meal-subscription operations platform and a matrimony platform — from schema to deployment.
01
Secure by default
Deny-by-default RLS, encrypted PII, audit-logged access — decided at the schema, not bolted on later.
02
Prove it with tests
Unit, RLS-aware integration and E2E passes gate every release. Green pipelines, not green promises.
03
Own the whole stack
Database, API, frontend, payments, deployment — one developer, one accountable codebase.

GoldenAxe Technology Solutions · Full-time · On-site
Sole full-stack developer on two production platforms serving real customers — owning database design, APIs, PWA frontends, payments, security and deployment end-to-end.
Meal-subscription operations platform: customer PWA, 29-page staff console, realtime delivery board, kitchen production planner and sales CRM — 55 pages, 65 DB migrations, 43 Postgres functions.
Production matrimony platform: member matchmaking app, 12-module admin console (38 routes), custom phone+PIN auth, installable PWA and PDF biodata generation.

Kongu Engineering College · Research project
Co-authored and published research on voice-based gender recognition, comparing CNN and RNN architectures on audio features. Improved generalisation across diverse vocal datasets with dropout and batch normalisation.
One year of solo shipping, reduced to numbers.

live · production · solo developer
A meal-subscription and delivery operations platform: customers subscribe through an installable PWA while staff run the business from a 29-page console — realtime delivery board, kitchen production planner, sales CRM and finance. 55 pages, 65 migrations, 43 Postgres functions, one developer.
live · production · solo developer
A community matrimony platform: members browse and match through a PWA, admins manage everything from a 12-module console with 38 routes, and biodata is generated as PDF on demand. 800+ real users migrated from a legacy system without a single lost record.

Let's connect and build something real.
Open to Full Stack and Backend roles — any location, immediate joiner. Happy to talk Next.js, Postgres RLS, payment integrations, or the platform your team is trying to ship with too few hands.
