Fractional CTO & AI Platform Architect turning ideas into measurable outcomes.
16+ years shipping production-grade AI platforms, scalable cloud systems, and high-velocity engineering teams across HRTech, HealthTech, IoT, and public sector — in India and South Korea.
I build at the intersection of Logic, Empathy, and Curiosity. Not just AI features — decision architecture that changes how organisations operate.
I believe great technology is human-centred by design — built with Logic to solve real problems, Empathy to serve real people, and Curiosity to keep asking better questions.
Currently: CTO at Noble House Consulting & OEAT (One Eighty Aamoksh Technologies)
Featured Work
Outcomes over algorithms. Here's how I've helped teams ship measurable results.
AI-powered ATS: 50% reduction in time-to-hire
Built a modular ATS with resume parsing, ranking, and analytics. Added eval harness and hiring funnels to halve time-to-hire.
AI-Driven Gig HR Platform: 25k+ workers at scale
Zero-downtime cloud migration: 60% scalability boost
Skills & Expertise
Building outcomes, not artifacts. I focus on small, end-to-end loops—ingest → infer → evaluate → iterate—with guardrails and observability from day one.
Fractional CTO
Align tech with KPIs; ship decisions, not decks.
Key Outcomes:
- •Define a 90-day roadmap tied to revenue, cost, or reliability KPIs
- •Stand up the right rituals (PRDs, ADRs, design reviews) to raise velocity
Tools:
AI Product Strategy
From prompt to production with evals & guardrails.
Key Outcomes:
- •Use-case scoring and cost/latency budgets
- •Evaluation harness (accuracy, bias, hallucination, drift)
Tools:
Platform Architecture
Design modular services with clear SLAs and cost/perf budgets.
Key Outcomes:
- •Domain boundaries that map to teams and roadmaps
- •Observability-first services with golden signals and SLOs
Tools:
Cloud & DevOps
Zero-downtime moves, IaC, and pragmatic reliability.
Key Outcomes:
- •Blue/green or canary releases with automated rollbacks
- •Terraform/IaC baselines; cost guardrails and alerts
Tools:
Compliance & VAPT
Close gaps fast—prove it with evidence packs.
Key Outcomes:
- •Map controls (ISO/GDPR) → implement → collect evidence
- •Threat modeling and VAPT remediation backlogs
Tools:
Team Coaching
Rituals, standards, and feedback loops that raise velocity.
Key Outcomes:
- •Pair reviews and design clinics; fewer reworks
- •Definition of Ready/Done that sticks
Tools:
Web & Mobile App Development
Cross-platform apps that scale from MVP to enterprise.
Key Outcomes:
- •Responsive web apps with modern frameworks (React, Vue, Angular)
- •Native and cross-platform mobile apps (React Native, Flutter)

Real feedback from leaders and teams I have partnered with — aligned to outcomes documented in case studies.
“Diwesh turned our vague AI idea into a shipped product with measurable business impact — in weeks, not months. He brought architecture rigour we didn't know we needed.”
Series B, 200+ clients
“The best thing about working with Diwesh is that he speaks both languages — deep technical architecture and clear business outcomes. Rare combination at the CTO level.”
Digital health platform, South Korea
“He built our ATS from scratch and it is now the operational backbone of our entire hiring operation. The evaluation harness he designed keeps the AI honest at scale.”
Noble House Consulting
“Diwesh restructured our engineering team rituals and within a quarter our velocity doubled and rework dropped significantly. He coaches engineers, not just code.”
150-person engineering org
“We brought him in for a cloud migration that three other vendors said would take 18 months. He delivered zero-downtime in 6. The IaC he built still runs our infra today.”
