Available for AI platform, systems and security work
New in 2026: TabSpawn, Bol, Jugnu II and 27 more00 · Ahmad Zushan · Delhi, IN · AI, Systems & Platform Engineer
AI/ML engineer working end to end: OCR and vision-LLM pipelines, fine-tuned models, LLM agents behind guarded APIs, kernel-level observability, LLM security, and the nginx, systemd and GPU infrastructure it all runs on. I ship the model and the platform around it.
01 · Flagship work
Document AI at scale, a live AI stage co-host, kernel-level data-flow security and real-time telephony. Case-study PDFs are attached where they exist.

One FastAPI platform, three use cases: handwritten-invoice extraction, long legal-PDF summarisation, and retail-display compliance scoring.
An AI that performs on stage with a human MC using real-time voice, plus a face-recognition reception desk: four production services.
Host→nucleus→backend platform that sees what apps send out over HTTPS, without decrypting TLS, at about 0.7% host CPU over millions of events.
A live airline voice bot: the caller speaks naturally, the system understands intent, calls real business APIs, and speaks the answer back into the same call.

Next.js/React and Django/FastAPI/Node products, static generators, WebAssembly and canvas games, WebRTC rooms, strict CSP deployments.
04 · Journey
Spec first, mock-first processors, then real inference behind an unchanged contract. Everything I build I also deploy, monitor, back up and, when it breaks, recover.
Start a conversationSchema-aware NLP-to-SQL (GPT-3.5), Llama 2 + TF-IDF transcript classification and retail forecasting: the foundations of the later agent work.
eBPF outbound data-flow agent and nucleus, an LLM prompt-injection WAF, the Crayto Zero-Trust extension and MMTC fleet hardening.
Haier invoice, legal and compliance pipelines, the PaddleOCR microservice and a nine-tool preprocessing toolkit.
5,000-RPM vision-LLM serving with failover, then a six-model VLM fine-tuning programme distilling cloud VLMs onto one A10G.
Unified compliance SaaS, Salesforce analytics agents, the meter-OCR pipeline and QUIN, a live AI event co-host with face-recognition reception.
FormReady, DocTools, ClipBridge, CutReady, RetroDeck, Emulator Hub, RetroDeck Live, Dusk Duel and a multi-tenant commerce platform, plus the msju.in and Healtharo client sites, all shipped and operated on self-managed servers.
TabSpawn with seven original browser games, Jugnu II in 3D, Bol Urdu voice typing on the web and Android, Folio, MLTools, RetroDeck Live PS2, a 28-hour Urdu speech dataset, narrated product walkthroughs, and a server consolidation backed by a verified full backup.

Newer work from August to October 2026, listed separately from the portfolio above: products under zooshan.com, a games portal with original titles, Urdu voice and speech tooling, research notes, client websites and the server that runs them. Filter by kind; every entry opens a short case page, and live ones link out.
Tell it what the portal asks for (JPG, 200×230 px, 20–50 KB) and get a file that passes: photos, signatures, scans, PDFs and the numbers portals ask for.
Thirteen server-side PDF and vector tools in one focused workspace: merge, split, compress, protect, unlock, watermark, number, clean metadata, convert, and trace images into real vector paths.
Private text, links and files shared between your own devices, with connections between accounts, directed transfers, live updates and single-use guest links.
Calligraphy, stickers, vinyl, laser and CNC tools that turn a typed name into a file the machine accepts, entirely in the browser.
Annotation (boxes, polygons, OCR, NER, classification), dataset splitting and validation, fine-tuning calculators (VRAM, training time, learning-rate schedules), ONNX and tokenizer inspectors, and JSON, YAML and regex utilities, with nothing uploaded.
The front door for the product family: it explains which tool fits which job, hosts long-form guides on application photos, PDFs and file sharing, and carries the studio's privacy commitments.
A multi-tenant commerce platform: a fast storefront for every store, a merchant admin, GST-aware pricing and promotions, and payment gateways, running today with a demo store.
The front door for my browser games: seven original titles built for the site, mirrors of Jugnu II and Dusk Duel, a retro lab, shared player names with public Top 10s, and long-form guides.
A Mini-Militia-style 2D deathmatch for up to eight players per room, bots filling the empty seats, six themed maps, and a zero-dependency Node server with a hand-written WebSocket implementation.
A remake of my 2016 M.Sc. game: a firefly whose light fades, stars that refill it and hazards that knock it down, now in 3D across five zones with a global Top 10 and an Android build.
An original two-player fighting game: pick a fighter, share a room link and play best-of-three rounds peer to peer, with nothing to install and no account.
Load your own PlayStation disc images and BIOS and play privately in a modern browser; nothing is uploaded.
One page for many systems: arcade, Nintendo, Sega, Sony, Atari and classic computers, each running lawful backups locally in the browser.
Play a two-player PlayStation game with a friend in another city: the console runs once on the server and streams to both browsers, each holding its own controller.
The PlayStation 2 sibling of RetroDeck Live: PCSX2 runs unmodified inside a sandbox with a virtual display and sound server, streams to both players, and keeps each person's uploads in a passphrase-protected library.
A phone-first Urdu editor with document layouts and PDF export, Whisper transcription on the server or on the phone, and a context corrector that fixes sound-alike mistakes.
A Windows app that records Urdu readings, aligns every word against what Whisper heard, clips the misses and exports a fine-tuning set, plus a complete LoRA pipeline for a 12 GB GPU.
A tray-launched desktop app pairing faster-whisper with PaddleOCR: transcription, document OCR to Markdown, and a per-line Hindi + Urdu + English mode, all on a 4 GB laptop GPU.
Upload a PDF, scanned or digital, read it as properly set pages, tap a word for its meaning in that sentence, and have the book read aloud, with the narration interruptible for a spoken question.
A 30,128-clip, four-voice Urdu corpus built from public-domain sentences and synthesised through Azure Speech, packaged with checksums, review pages and a phase-by-phase roadmap for training a Piper or F5 voice.
The platform version of QUIN: vendors build voice agents that call APIs and databases through tools with confirmation policies, ground answers in their own documents, and design conversations in a visual flow studio.
Walkthrough and promo videos for ClipBridge, RetroDeck Live, FormReady, Bol and Jugnu II in English, Hindi and Urdu: scripted headless-Chrome recordings, AI narration, captions, and a frame-by-frame check against the words.
Step one of a browsing agent that runs on my own model: code, not an LLM, turns any rendered page into a short text map of roles, names and targets that a small fine-tuned model can act on.
Can four laptop cores outperform a GPU? Only through asymmetry: an inverted-file retrieval kernel beat the GPU's roofline floor 18.9× at 100% recall, and the write-up says exactly where the trick stops.
An ESP32 driving a 128×64 OLED over I²C with a drifting aurora animation in MicroPython: the smallest project here, kept because the fix was the oldest kind.

A 67-page catalogue site for a Sambhal herbal manufacturer: product families, compositions, classic Unani ranges, quality pages and WhatsApp-first contact.
A new identity for a scholar's lecture website, marble and walnut with turquoise and carnelian touches and a pointed-arch motif, built as a separate static generator and shown on a staging host before anything in production changes.
Every product, game and client site here runs on a single 2-vCPU virtual machine: twenty-two nginx virtual hosts, Docker Compose and systemd services, Let's Encrypt certificates, release directories and tested rollback.
A read-only page listing every site and application on the server with bot-filtered traffic, the release that is live, certificate expiry, systemd services, containers and resources, regenerated hourly behind basic auth.
