Core Capabilities

Built To Ship, Not Just Demo

Full-Stack Engineering

From schema to UI — Next.js and Node.js APIs backed by PostgreSQL, built the way SmartERP was: modular, typed, and paced for a 14-day sprint, not a weekend hack.

Next.jsNode.jsPostgreSQLTypeScript

ledger.service.ts

// SmartERP — double-entry post
export async function postEntry(tx) {
  const balanced = tx.debits === tx.credits;
  if (!balanced) throw new Error('Unbalanced entry');
  return db.ledger.create({ data: tx });
}

Cloud Deploy, Debugged Live

When AWS Elastic Beanstalk hangs on t3.micro, I don't just restart it — I SSM into the instance and fix it surgically. Same discipline keeps api.vasutech.online up for DocSign.

AI Where It Adds Value

Groq-powered resume parsing and career coaching inside the Skill Gap Analyzer — fast inference, free tier, zero bloat. AI as a feature, not a gimmick bolted on for the demo.

Data Modeled Right

Prisma-managed PostgreSQL schemas that hold up under audit trails and role-based access — the backbone of DocSign, the Bug Bounty Platform, and SmartERP alike.
