Software Engineering Intern

Adaptware Solutions Pvt Ltd.

Mar 2026 - Jul 2026

Chandigarh, India

01

Developed recruiting and AI-workflow features in a monorepo of 2 independently deployable Fastify microservices, with separate PostgreSQL schemas, Redis-backed workers, and shared npm packages.

02

Engineered a TypeScript integration layer to the Orion AI service, enabling 20+ AI workflows across 12+ modules including resume processing, job creation, candidate screening, assessments, and interviews.

03

Built Socket.IO workflow execution with concurrency throttling, supporting up to 50 parallel AI runs per backend instance.

04

Added JWT auto-refresh, request correlation, connection reuse, and timeouts, keeping AI socket sessions authenticated across long-running executions.

05

Implemented multi-turn workflows with LangGraph checkpoints and Redis, preserving state across 5+ conversational flows such as job intake, resume building, and application screening.

06

Integrated sentiment analysis into live interviews every 30 seconds, streaming results to interviewers via Socket.IO.

07

Integrated recruiter-assist live interview analysis every 2 minutes, persisting insights to PostgreSQL.
