The Doodleverse

A little hand-drawn universe by Ansh Singhal — India-based ai/ml & backend engineer. Wobbly planets, cozy music, and real systems underneath: an AI gateway at 100k+ RPS, 100% zero-day recall, agentic RAG over 10K+ docs.

the work

things I’ve actually built.

open a planet — each one is a real system, drawn + measured.

AI Security Gateway

A production AI security gateway I own end to end — backend, frontend, DevOps, cloud, and scaling — that fronts 500+ endpoints, enforcing pre/post-LLM security and scaling with async concurrency from 100 to 100k+ RPS.

ZeroDayShield

An independent zero-day research engine I lead and build from scratch — 50+ custom static-analysis engines (zero open-source libraries) mining live registry traffic across npm, MCP servers, Docker images, and Hugging Face models, with a multi-stage LLM triage pipeline at 100% recall and 93% precision.

DHARA

An agentic RAG engine for legal research over 10,000+ documents — 97% retrieval accuracy, citation-traced answers at sub-500ms P95 — with multi-agent query decomposition, reranking, and deterministic grounding on AWS microservices.

VoiceOps AI

A real-time voice-streaming backend holding sub-200ms latency across 100+ concurrent sessions — WebSocket ingest, Kafka consumer groups, and Kubernetes HPA that autoscales on consumer lag.

Flood-GAN

A physics-aware GAN that translates all-weather SAR radar into optical-quality flood imagery at 1024×1024 — published research, with a dual-head generator that learns flood boundaries as water, not texture.

about

The play is new. The receipts are not.

I'm Ansh Singhal — an AI/ML & backend engineer at CyberUltron, building from India. It's playful on the surface and seriously built underneath: every doodle-planet here opens into a real system I operated, with the real measured numbers.

how I got here

IntelOwl first — production security analyzers, a Celery async pipeline, Docker-and-migration trenches. Then CyberUltron: an AI security gateway I own end to end, every prompt across 500+ endpoints passing through it before a model ever sees it — scaled with async concurrency to 100k+ RPS.

what I optimize for

Throughput and tail latency you can feel. The gateway: 500+ endpoints, 100k+ RPS. ZeroDayShield: 100% recall at zero false positives. DHARA: 10K+ docs, sub-500ms. I size systems for storms, not averages — and keep the numbers honest.

why this site works the way it does

Hiring pages shouldn't read like templates. I wanted the abstractions I care about — queues, caches, backpressure, reranking — to be things you can poke and watch respond, that still hand you a measured number when you lean in.

where I’ve shipped.

CyberUltron

Feb 2026 — Present

Remote

AI/ML Engineer

Sole owner of a production AI security gateway — backend, frontend, DevOps, cloud, and scaling — fronting 500+ endpoints at 100k+ RPS, plus DevSecOps (CBOM/SBOM) and endpoint-governance work across the platform.

  • Architected and shipped a production-grade AI security gateway as sole owner across backend, frontend, DevOps, cloud deployment, and scaling — centralized pre/post-LLM security (SHA-256 auth, PII detection, prompt-injection mitigation) across 500+ endpoints, scaled with async concurrency to 100k+ RPS at a 99% reduction in unsafe LLM behavior.
  • Drove critical feature expansion on an application-security (DevSecOps) platform — introduced CBOM scanning coverage, shipped AI-powered vulnerability remediations that cut manual triage time by 60%+, and optimized platform performance by 40%+.
  • Engineered core features on an endpoint AI-governance solution guarding against sensitive-data exfiltration across 5+ widely-used enterprise AI tools — a lightweight agent + local-proxy architecture serving 1000+ enterprise endpoints.

IntelOwl

Jan 2025 — Apr 2026

Open Source Developer

Shipped production code into an open-source threat-intelligence platform used by security teams worldwide — 4 security analyzers, +23% detection coverage.

  • Contributed 4 production security analyzers to IntelOwl, an open-source threat-intelligence platform used by security teams worldwide, expanding automated threat-detection coverage by 23% across IP addresses, file hashes, and URLs.
  • Added pytest-based validation suites to improve analyzer reliability and regression protection.
  • Fixed Django migration and data-consistency issues, improving migration success to 99.9%.
  • Resolved Docker networking and caching issues to improve deployment stability and analyzer execution.
