Software Engineering Intern@Inseconds

Jan 2026 — Present

Remote

  • ▹Engineered a personalized reel recommendation engine using a weighted scoring model (interest match, quality, recency), delivering 20+ tailored reels per request with interaction tracking and interest profiling.
    PostgreSQLRedisRecommender
  • ▹Built a hybrid candidate search engine — pgvector (HNSW) + tsvector at a 70/30 semantic/full-text blend — with Voyage AI embeddings and Claude Haiku NL query parsing, giving recruiters sub-second natural-language search over 1024-dim resume embeddings.

  • ▹Reduced cloud storage costs by 40%–95% with S3-based media compression pipelines on FFmpeg; offloaded processing to AWS Lambda, removing EC2 CPU overhead.

  • ▹Scaled email infra from Gmail SMTP to AWS SES — 500 → 50K daily emails — with Handlebars templates, OTP workflows, and HMAC-based unsubscribe.
    AWS SESHandlebars
  • ▹Orchestrated RBAC-based PostgreSQL migrations to unify HR systems: data backfill, session consolidation, zero-downtime rollout, no service disruption.
    PostgreSQLRBACMigrations
  • ▹Migrated a legacy Node.js backend to TypeScript with zero downtime — typed models, Zod validation, structured error handling, standardized APIs.

# whoami

Information Technology undergrad who lives in the terminal and thinks in systems.

I like the unglamorous parts of software — recommendation engines, hybrid search, media pipelines, zero-downtime migrations — the stuff that has to actually work at scale.

Competitive programmer, open-source tinkerer, and a perpetual computerphile chasing how things work under the hood.
