AI engineering · Hands-on founder · Singapore
Arunank Sharan
AI systems, from customer problem to production.
Cofounder of Skai Labs in Singapore, leading the company and building multiple AI projects for Singapore clients.
Founder of Kuzushi Labs, building AI systems that help teams research companies, handle customer calls and coordinate day-to-day operations. The work spans client discovery, architecture, hands-on development and delivery — with 20+ clients and a team of 10+ engineers.
Open to senior AI and forward-deployed engineering roles, and Staff/Principal engineering opportunities.
Selected work and business outcomes
All projectsWhat each system does, the work it takes over and the result for the business.
01 / Investment research · Finding and checking evidence
Company research without searching every report by hand
Equity analysts can ask questions across more than a million company filings and earnings-call transcripts, compare financial results and open the exact passage behind an answer. The AI handles finding and assembling evidence that analysts would otherwise search for document by document.
The platform was delivered in six weeks. Changing how documents were processed reduced the estimated cost of processing the complete collection from US$120K to about US$48K — 60% lower, within the US$50K budget.

02 / Hospitality · Guest service and maintenance coordination
Guest questions answered. Maintenance requests turned into work.
Guests can get property information, check availability and report maintenance problems through an AI assistant. It answers routine questions, guides booking requests and turns reported problems into tracked work for staff, taking over repetitive information lookup and issue recording while keeping permissions and approvals with the business.
Guests received answers or a recorded next step. The operations team could inspect completed actions, investigate failures, test changes and track the cost of running the assistants.

03 / Customer calls · Information gathering and handoff
Routine customer calls handled by AI phone agents
AI phone agents handle routine insurance, healthcare and education calls: they collect customer requirements, capture appointment requests and arrange callbacks or handoffs. This automates information-gathering conversations that staff would otherwise conduct one call at a time.
The early-2025 platform handled 40 calls at the same time, with responses in approximately 1.1 seconds. Testing reached a maximum of 100 concurrent calls.
Python · Bolna / Pipecat · Streaming · Kubernetes
Quant research: AI-assisted workflows gather research, coordinate calculations and assemble findings for a trading team to review. The public demonstration shows the work around an investment decision; the team retains the decision itself.
Experimental · Work in progress · Internal R&D
A solo company, coordinated by AI agents
An internal experiment to help one founder coordinate enquiries, quotes, delivery, support and finance. Shared records keep customer commitments connected; agents prepare the next step and bring decisions back for review.
The local prototype spans 11 core business loops. A 40-part series walks through the architecture, 14 business workflows, connector contracts and the custom agent harness being developed above them.
Architecture, code and delivery ownership
From requirements to production
Client discovery and technical scoping lead into service design, model selection, implementation and deployment. Budget, latency, permissions and evaluation shape the architecture from the beginning.
Technical direction with hands-on execution
At Kuzushi Labs, the role combines building the engineering team, mentoring 10+ engineers and making buy-versus-build decisions with direct implementation across Python, TypeScript, data services and cloud infrastructure.
- Athina.ai
- Founding AI Engineer: full-stack evaluation, experimentation and monitoring tools for AI pipelines.
- Reliance Jio
- Built the Jio Health platform for COVID-19, serving 10M+ daily active users through MyJio. Machli, an AI-powered multilingual advisory app for fishing communities, won the World Summit Award (2021) and Aegis Graham Bell Award (2019).
- Skillate
- Delivered ML recruitment systems to 10+ enterprises; reduced matching response time from 9 seconds to under 0.7 seconds.
