The short version
Ambiguous problems become shipped systems — across logistics, fintech, and AI.
01
Closing the loop between building and measuring.
A builder who finishes. In every project, the interesting part is the decisions — what to build, what to cut, and how to measure whether it moved the needle. Engineering is the unfair advantage; instrumentation is what stands out.
Across two internships and a hackathon win: event-driven services, 40+ REST APIs, a serverless voice assistant, and a published benchmark study. Impact isn't claimed — it's instrumented, defended with numbers, and written about in public.
Currently a remote Software Engineering Intern at Software Tree (USA), building a 24/7 inventory-monitoring agent on a JSON-RPC backend, while studying CS at BITS Pilani and Data Science at IIT Madras simultaneously.

Things I'm known for
- 01Published a 33-minute benchmark essay on the hidden cost of AI database access.
- 02Audited the railway system like a stranger would — the proudest feature turned out to be the biggest bottleneck.
- 03Removed the LLM from the monitoring loop after measuring that arithmetic beat aesthetics.
02
How I think
Engineering is a series of decisions, not a pile of features. Build the smallest honest version, measure whether it worked, and let the number — not the aesthetics — make the call.
“Rules where you need vigilance, AI where you need judgment.”
“Ask what breaks at 100× before shipping — and audit your own work like a stranger would.”
“The right unit is cost per convinced customer, not cost per minute.”
“When a false positive costs a career, AI advises and humans decide.”
03
Where I've shipped
Two internships building real, tested software — in the USA and for Indian Railways.
Software Engineering Intern
Oct 2025 — PresentSoftware Tree, LLC · USA · Remote
- Owned end-to-end design of a 24/7 inventory-monitoring service — an event-driven agent over a JSON-RPC backend that auto-detects low-stock items, computes reorder quantity, and dispatches alerts, replacing manual stock checks.
- Designed and ran a 20-session controlled benchmark across 4 tasks on GPT-5.4 + Claude-4.6, instrumenting tokens, cost and latency, and cut token (compute) cost by up to 58% for graph-shaped workloads.
- Built a reusable Python JSON-RPC client with Server-Sent Events streaming and session handling, giving the team typed, schema-safe data access in place of raw SQL.
- Raised release quality across 9 release iterations on live PostgreSQL / Oracle / MySQL / H2; root-caused a reproducible defect with a workaround and surfaced 2 JDBC blockers.

Software Development Intern
May 2025 — Jul 2025Centre for Railway Information Systems (CRIS) · India
- Designed and shipped a full-stack Parcel Management System end-to-end: 40+ REST APIs across 6 modules over a 5-table relational schema, JWT role-based access for 3 roles, and Docker Compose deployment with durable volumes.
- Engineered password-less OTP login with a 3-tier email failover (Gmail → Postmark → RapidAPI) that keeps authentication working when any single provider fails, plus a network-wide audit log.
