Engineer of unlikely
systems. Nine production builds across AI, infra, IoT, mobile, and commerce.

I build software that has to actually work — autonomous AI agents, enterprise-grade APIs, predictive maintenance pipelines, and the occasional multi-tenant smart-home stack. Founder–engineer, ex-cloud architect, currently building Eval8.ai.

⏺ Strategic Partnership · 2026

Hysteresis is now an
official NVIDIA partner.

Joining NVIDIA's partner ecosystem unlocks direct GPU compute access, early CUDA & cuDNN tooling, and joint go-to-market on enterprise AI infrastructure deployments. For Eval8.ai, that means on-prem inference at scale — sovereign LLMs running on NVIDIA hardware inside customer perimeters.

A vertically integrated platform replacing the assessment, training, and proctoring stack for engineering colleges and recruiters. Built on a local-first AI architecture that hits ~90% gross margins at ~₹12,999/student — a number nobody in this category has touched.

Hyper-innovative bits

  • Autonomous Learning & Curriculum Tuning System (ALCTS) — ingests live job descriptions, reverse-maps them to skill graphs, and auto-generates per-student curriculum that mutates as the market shifts.
  • Sovereign AI Interviewer (SAII) — runs entirely on-prem on Apple Silicon: Whisper STT → local LLM → Kokoro TTS. Zero data leaves the college network. Patent-pending.
  • Behavioral Integrity Scoring — Chrome DevTools Protocol screen capture + Qwen vision model fuses gaze, tab-switching, and keystroke biometrics into a single integrity score. No proctor needed.
  • Prompt-to-Hire Engine — recruiters describe a candidate in plain English; the engine retrieves, ranks, and books interviews end-to-end.
  • AI Desktop Learning Agent "Tux" — a personality-driven agent that drives VSCode, browser, and terminal to teach by demonstration. Four mood modes.

DoSelect API Gateway

Naukri.com · Candidate parsing & assessment routing

Built the core API gateway powering candidate-resume parsing and assessment dispatch for DoSelect (a Naukri-owned product). The kind of system where a 200ms regression is somebody's bad Monday morning.

Hyper-innovative bits

  • Schema-aware throttling — rate limits adapt per endpoint based on payload entropy, not just request count.
  • JWT-with-rotating-claims — tokens carry per-tenant feature flags that flip without re-issuing.
  • Multi-format resume parser — PDF, DOCX, image-based; falls through OCR with confidence scoring.

NaturesDeli

Grocery e-commerce platform

End-to-end grocery commerce stack — catalog, cart, payments, last-mile dispatch. Built for cold-chain SKUs with route-optimized delivery windows.

Hyper-innovative bits

  • Cold-chain aware fulfilment — SKUs tagged with thermal envelopes; dispatcher refuses incompatible co-loads.
  • Inventory de-duplication across third-party suppliers.

Vishq.io

Smart-home automation OS
5 nodes · MQTT · 24ms avg

A protocol-agnostic smart-home control plane. One UI, every device.

Hyper-innovative bits

  • Mesh-first — devices coordinate locally even if internet drops.
  • Intent automation — "wind down for the night" resolves to a learned action graph.

Smallest.ai TTS

Internal freelancer · Protocol & param testing
SAMPLE_RATE: 24000Hz LATENCY_P99: 84ms ✓ 12 voices · 9 langs · benched

Tested and tuned TTS protocols and parameters across voices and languages for one of India's fastest TTS startups.

Hyper-innovative bits

  • Latency-perceptual tradeoff harness — automated benchmarking against MOS scores.
  • Streaming-first first-token-out budgeting under 100ms.

Torry Harris × Azure Entra

Custom authentication protocols on Microsoft Entra ID
CLIENT ENTRA ID + CAE RESOURCE Conditional Access · Token Bind · MFA PKCE + DPoP · token leak ↓ 100%

Designed custom auth flows on Azure Entra ID — Conditional Access policies, DPoP-bound tokens, and a custom claims pipeline that reduced token-leak surface materially.

Hyper-innovative bits

  • DPoP-bound tokens — proof-of-possession tied to client key; replay-attack resistant.
  • Continuous Access Evaluation with custom risk signals from device posture.

Observability stack for telco-grade workloads
node_cpu_usage{quantile="0.99"} 15m · 1h · 6h · 24h · 7d

Stood up the metrics + alerting backbone for high-volume telecom workloads — custom exporters, alert routing, and SLO dashboards that ops actually opens.

Hyper-innovative bits

  • SLO-based alerting — burn-rate alerts replace static thresholds.
  • Multi-tenant Grafana with per-team RBAC and folder-scoped dashboards.

Hindustan Unilever · Predictive Maintenance

ML pipeline for industrial uptime + capability transfer workshop
SENSORS INGEST FEATURES MODEL ALERT + DIGEST vibration temp current Kafka 10K/s FFT rolling stats XGBoost RUL Slack · SAP PM-order

Built a predictive maintenance solution for HUL's manufacturing lines — sensor ingest through XGBoost-based remaining-useful-life modeling, with automated work-order creation back into SAP. Then ran a workshop to hand it over to the in-house team.

Hyper-innovative bits

  • FFT-derived features — vibration spectra collapsed into a 32-dim feature vector that XGBoost handles cleanly.
  • RUL (Remaining Useful Life) regression instead of binary classification — operators get a horizon, not just a yes/no.
  • SAP-PM auto-ticketing — alerts don't end in Slack; they create the maintenance work order.
  • Capability transfer workshop — full hand-off so HUL's team owns it, not us.

28 layouts

A gamified personal-productivity Android app — built natively in Android Studio with Java/Kotlin and pure XML-based view rendering. Every habit, daily, and to-do becomes a quest; consistency earns XP and gold, slipping costs HP. Built from the ground up with custom XML layouts (no Jetpack Compose), demonstrating mastery of Android's classic rendering pipeline.

Hyper-innovative bits

  • Pure XML rendering pipeline — every screen built with native Android view hierarchies (LinearLayout, ConstraintLayout, RecyclerView, CardView), with custom drawable XMLs for state-driven animations. No Compose, no shortcuts.
  • Dual-currency RPG mechanics — HP/XP/Gold economy where positive habits add XP and missed dailies subtract HP, creating real behavioural feedback loops.
  • Custom view components — built reusable XP progress bars, quest cards, and avatar widgets as <custom-view> XML tags with Kotlin-backed render protocols.
  • Selector & state-list drawables — task buttons morph through pressed/checked/levelled-up states using XML state machines, no third-party animation libs.
  • Material Design adherence — every dimension, padding, and elevation traced back to Material spec via styles.xml + themes.xml.
  • Offline-first room database — SQLite via Room, so quests persist even without connectivity. Sync layer queues actions for later.
