# Sethukumar Ramachandran on Tal

## Headline

Technology & Engineering Leader \| Independent AI Research & Experimentation \| LLM Evaluation • AI/Data Quality • Ontology & Knowledge Graphs • Enterprise AI

## About

25\+ years across software engineering, architecture and technology leadership, with recent independent research focused on a practical question: what does it take to make enterprise AI trustworthy, explainable and operationally useful? My research began with a hands\-on experiment to build a domain\-specific LLM for Java code review\. Evaluating the system led to an unexpected observation: different LLMs could assess the same output differently\. That question became the starting point for a broader investigation into AI evaluation, data quality, knowledge representation, ontology, knowledge graphs, context, governance and enterprise AI architecture\. The work has since evolved from experimentation into building and testing an enterprise\-oriented platform, including evaluation, governance, guardrails, provenance, validation and real\-world usage\. I document the journey openly through engineering journals, design notes and working experiments — focusing not only on what works, but also on failures, disagreements, gaps and what those observations reveal about building dependable AI systems\. I am particularly interested in opportunities involving AI evaluation, applied AI research, enterprise AI advisory, knowledge engineering, AI/data quality, architecture reviews and project\-based technology research\.

## Work experience

Founder \(solopreneurship\) at Samvit Career Architects, Oct 2025 \- Jul 2026 · 10 mos, Bengaluru, Karnataka, India, Founded and built a career\-architecture practice combining psychometric analytics with personalized career guidance — designed the full engagement model \(exploratory assessment → behavioral analysis → multidimensional psychometric evaluation → technology trends, tailwinds and headwinds → transformational nature of careers and adaptivity → career architecture score → gaps and blind spots detection and calibration → what\-if scenario planning → data\-driven recommendations\) for students and professionals\.

Engineering Manager at Quinbay, Jan 2022 \- Aug 2025 · 3 yrs 8 mos, Greater Bengaluru Area, Replaced a $20M SAP dependency with a B2B marketplace now live at business\.blibli\.com — led engineering delivery end\-to\-end \(Java, Spring Boot, microservices, Kafka, MongoDB, PostgreSQL, GCP\), eliminating $20M in annual licensing costs and lifting business\-operations efficiency 25% in the initial adoption phase\. Integrated cleanly with Blibli's existing catalogue, shipping, and warehouse systems\. Re\-architected a price intelligence platform from monolith to independently\-scalable services — 30% increase in scalability, 100% of pricing workflows automated, removing the cross\-team dependencies that had throttled scaling\. Took a dynamic pricing POC from idea to working system — built a Drools \+ Spring Boot rules engine that collapsed the update\-propagation delay across pricing systems; the work was published as a pricing intelligence paper and is now the live pricing engine\.

Senior Architect at Infostretch, Oct 2021 \- Dec 2021 · 3 mos, Greater Bengaluru Area, Ran pre\-sales architecture assessments for multiple enterprise clients, translating business constraints into buildable technical roadmaps\.

Technology Manager at ANZ, Jul 2017 \- Mar 2021 · 3 yrs 9 mos, Greater Bengaluru Area, Replaced a Thomson Reuters vendor feed with a home\-grown streaming REST API for currency exchange data — 30% licensing cost savings, 20% faster data access, removing a proprietary dependency from a core trading system\. Cut deployment time 50%\+ by building automated CI/CD pipelines across multiple applications, reducing production downtime and enabling significantly higher release frequency per sprint\. Brought P0\-adjacent incident response time down 30% by redesigning application logging for full traceability on milestone events and error detail — cut bug reports 15% as a direct result of more actionable alerting\. Led the Global Markets Portal roadmap, shipping features that drove a 20% lift in user engagement\. Ran a Kafka POC to stream payment lifecycle events, improving transaction tracking 20% and giving the business a data\-backed view of customer behavior for root\-cause analysis and story\-writing\. Owned application security as the team's secure\-coding champion\. Stack: Java, Spring \(Boot/Security/Cloud\), Hibernate, Kafka, Docker, RabbitMQ, HP Fortify, React, AWS\.

Solutions Architect at NuVizz India, Dec 2015 \- Jun 2017 · 1 yr 7 mos, Designed the trip\-assignment algorithm that improved route efficiency 25% — the team's core differentiator, and the reason the team won the company's Best Development Team award\. Took the application server from bottleneck to scalable — 25% throughput increase, 20% reduction in load times\. Led the monolith\-to\-microservices migration, cutting deployment time 30% and unlocking independent scaling for critical features\. Redesigned the data layer twice for resilience: MySQL master/slave with CQRS\-style read/write routing \(18% DB performance gain\), and a move from in\-container caching to distributed Couchbase \(15% performance gain, improved stability under load\)\. Introduced Redis\-backed session storage to remove session affinity from the cluster, cutting downtime 25%\. Mentored the development team through the architectural refactor to a 95% on\-time delivery rate and a 20% improvement in code quality\.
