We build AI
that actually
ships.
LLMGuys is an elite AI and MLOps agency from the hills of Shillong. We design, train, and deploy production-grade AI systems — not prototypes that die in staging.

AI Product Engineering
From fine-tuning LLMs to shipping neural TTS and multimodal search — we design and launch AI products that users actually want to use. Real models. Real pipelines. Real users.
- LLM finetuning & RAG systems
- AI-powered SaaS product development
- Multimodal AI — vision, voice, video
- Custom model training & ONNX optimization
MLOps & Infrastructure
Production ML pipelines that don't fall over at 3am. Cost-optimized inference, cross-cloud autoscaling, and deployment automation built to outlast the hype cycle.
- ML training & deployment pipelines
- Inference optimization (1.5× throughput)
- Cross-cloud autoscaling & cost control
- MLFlow, KServe, RabbitMQ
Platform Engineering
We migrate, scale, and harden cloud infrastructure with zero downtime. Full observability baked in from day one — because you shouldn't find out about outages from your users.
- Kubernetes & Istio deployments
- Observability stack (OTel, Grafana, Loki)
- Zero-downtime cloud migrations
- Incident response & alerting (sub-2min MTTD)
Full Stack Development
Scalable web applications architected for real growth — from MVP to millions of users. We've built it, scaled it, migrated it, and kept it running. Ask us about the 5M DAU platform.
- Next.js, Nest.js, React
- MongoDB, microservices architecture
- Real-time collaborative systems (CRDT)
- Payment systems & analytics
Projects that moved
the needle.
Quillbot AI Suite
Single-handedly designed and launched 5+ production AI products at one of the world's leading writing tools — including neural TTS with custom voice synthesis and a Gemini-powered AI search engine. Achieved 1.5× inference throughput via ONNX quantization and FasterTransformer, and built a cross-cloud autoscaler that cut costs by 20% across AWS, GCP, Coreweave, and Hetzner. Boosted GPU utilization by 150% through MPS multiplexing on T4, A100, and L40s.
GKE Migration & Observability Overhaul
Executed a zero-downtime migration from App Engine to GKE with Istio service mesh, generating $500K+ in monthly savings. Simultaneously deployed a complete observability stack for under $1K/month using OpenTelemetry, Grafana, Tempo, Loki, and Thanos — with sub-2-minute MTTD via event-driven PagerDuty and Prometheus alerting.
Real-Time Collaborative Editor at 5M DAU
Engineered a real-time collaborative editing platform serving 100K+ MAU using MongoDB sharding and YJS CRDT algorithms. Built the foundational architecture to handle 5M daily active users with Next.js SSR, Nest.js microservices, and MongoDB clustering. Reduced payment disputes by 75% (0.4% → 0.1%) via ML-based fraud detection with Stripe Radar. Executed a zero-downtime migration from Firebase Firestore to MongoDB Atlas with full consistency validation.
Tamanna — AI Fashion & Video Platform
Built a cutting-edge AI-powered fashion and virtual photoshoot platform. Trained and optimized Wan2.2 Face LoRA for Image-to-Video generation with high-fidelity identity retention. Integrated Qwen Image Edit for controllable inpainting, relighting, and pose adaptation. Engineered cross-domain CLIP-based style transfer pipelines replicating Pinterest-grade aesthetics, plus real-time neural face reenactment for live video streams.
BusRestro — IoT Fleet Management
Led ops and tech teams to deliver a $300K IoT fleet management contract for the Uttarakhand Transport Corporation. Then translated that technical execution into investor confidence — securing $53K in seed funding and a $5M Series A valuation from Pioneer Publicity Corporation and prop.in. The rare kind of project that proves technical depth and business acumen aren't mutually exclusive.
Aashis
Kumar
Based in the cloud-kissed hills of Shillong, Aashis Kumar is among India's sharpest AI engineers — currently serving as Staff MLOps Engineer at Quillbot, where he's single-handedly shipped 5+ production AI products and built infrastructure that serves millions of users daily.
He's been in the founder seat too. As CTO and COO of BusRestro, he owned the entire technology stack, secured seed funding from Pioneer Publicity Corporation, scaled the company to a $5M Series A valuation, and personally oversaw the hardware installation of GPS trackers and cameras across interstate bus corridors for the Uttarakhand Transport Corporation. Before that, he architected the full-stack platform at HeyHomie.me — powering WhatsApp-native storefronts, plug-and-play payments, Meta Business API integrations, and AI-driven customer retargeting for SMBs across India.
He was selected as one of just 180 Google Developer Student Club Leads across all of India — hosting events, mentoring projects, and giving talks on everything from Git and React to research paper writing. That same instinct to teach and build in public defines how LLMGuys operates: no black boxes, no bloated teams, just precise technical execution and clear thinking.
LLMGuys isn't a typical agency. It's a one-person force multiplier for founders and engineering teams who need AI done properly — with production-grade infrastructure, not slide decks and demos.
5+ AI products shipped. 100K+ MAU.
