Sr. Cloud Architect & Engineering Leader | Live AWS→Azure • Estate Rewrites • LangChain / Agentic AI | Multi-squad delivery

About

I walk into estates everyone is afraid to touch — bloated codebases, fragile platforms, migrations that “cannot fail” — and I take ownership. I do not decorate broken systems. I challenge them, cut them to what is essential, and lead teams through the uncomfortable rewrite — live, at scale, with production on the line. What I do • Large-estate modernisation & rewrite — diagnose rot, prove one vertical slice, strangler-fig the rest (DDD, design patterns, microservices patterns) • Live cloud migration — AWS → Azure with zero-downtime cutover, IaC, managed Kafka/search/cache, active-active / DR • High-throughput distributed systems — hot-key/cache redesign, event-driven flows, single-digit ms where it matters • AI that ships — LangChain, agentic & multi-agent APIs, Azure AI / RAG-ready pipelines, human-in-the-loop — inside real service boundaries, not slide decks • Delivery leadership — multi-squad programmes, Design–Develop–Run, architecture runway, CI/CD as habit Proof, not theatre • Tesco order estate: ~500M API hits/day • live AWS→Azure • Java 11→25 • ~500k → ~100k LOC • ~100B documents / ~100TB+ class archival moves via Azure Data Factory • GE Renewables: ~30k turbines • APIs from ~100ms+ → single-digit ms (~1k RPS) • Zebra: OTA microservices for ~2M handhelds (GCP) • PayPal: China residency migration APIs at 1B-record class (~1B calls/day platform) • Healthcare: FHIR/HL7 rewrite + Azure AI clinical docs; Engineering Manager for ~20+ engineers • Smartneta: full election product rebuild (admin + Ionic Android/iOS) to production stores on AWS How I lead Decisive under ambiguity. Courageous with founders, CTOs, and directors — I tell the truth about risk, cost, and rewrite necessity, then deliver the plan that makes that truth survivable. I step toward the fire: live cutovers, collapsing p95s, rewrite politics. I raise the floor with standards and the ceiling with coaching — and leave teams faster and braver than I found them. Open to Sr. Cloud Architect / Platform Architect • Engineering Manager / SDM • Director / Head of Engineering conversations — India (Bengaluru), remote, hybrid

Work experience

Engineering Manager (Consultant) at Onyx, Nov 2024 - Present · 2 yrs, Bengaluru, Karnataka, India, Walked into a bloated FHIR/HL7 interoperability stack with low client confidence — named the rewrite, won founder/CTO and ~20+ engineer buy-in, then proved it. • Redesigned brittle Spring Boot into Spring Integration + Kafka event-driven flows with MongoDB job state for recoverable large-file processing • IDR/ETL: FHIR/CCDA/ADT → PostgreSQL / Snowflake with dependency graphs for dedup/versioning; CMS-oriented compliance contributions • Azure AI pipelines for clinical documents & medical images → structured clinical data, longitudinal views, payer risk scoring; RAG-ready document paths; Databricks at scale • Architect Nov 2024 – Apr 2025; Engineering Manager from May 2025 — people + delivery leadership across multiple leads/workstreams: priorities, quality bar, stakeholder confidence; AI workstreams that ship with observability, not demos

Principal Engineer / Architect (Consultant) at Smart Neta, Dec 2025 - Jun 2026 · 7 mos, Bengaluru, Karnataka, India, Primary engineering owner (with a product partner) for a full election-operations rebuild — admin + Ionic Android/iOS — from a near-unusable Java 8 / old Ionic stack. • Multi-tenancy, hierarchical surveys (state→booth), offline-first sync, geo-verification, multilingual UX, thermal-printer confirmation, map dashboards • Scale intent: large volunteer bases; voter datasets in the 10–100M class • AWS modernisation: containers, Terraform, GitHub Actions, Amplify admin, secrets/HA — Play Store & App Store production releases • Small team, large ambition — carried the technical weight end to end

Solutions Architect at Blooming Health, Feb 2024 - Jul 2025 · 1 yr 6 mos, Bengaluru, Karnataka, India, Social-care cloud product: multilingual IVR/SMS assessments (Twilio, Google Translate) and intelligent next-step automation. • Replaced callback spaghetti with Spring Integration, then layered LangChain workflows (tool-based next steps, human-in-the-loop) • Example agentic path: post-surgery pain signal → locality/availability tools → clinician suggestion → booking / transport — experimental honesty with funding constraints • Built CI/CD from near zero (backend, Amplify, Google container deploys) so a 0→1 product could scale after funding • Coached engineers on workflow standards and production readiness

SDE-III at Tesco Bengaluru, Dec 2023 - Sep 2026 · 2 yrs 10 mos, Bengaluru, Karnataka, India, Own platform and application outcomes for a retail order estate at ~500M API hits/day (~1M online orders/day, ~10M till orders/day). • Continue the estate transformation arc: live AWS → Azure with zero-downtime cutover; Terraform/Ansible IaC; Azure landing zones & PIM; AKS; Confluent Cloud (active-active); ECK; Redis/Couchbase replatforms; GitHub Actions + Argo CD / Argo Rollouts • ~100B documents / ~100TB+ class moves via Azure Data Factory (S3 → Azure Storage) • DR and active-active architectures for multi-region continuity • DDD-led order rewrite; Java 11 → Java 25; surface ~500k → ~100k LOC; resilience patterns (circuit breaker, fallbacks, bulkheads) • Multi-squad delivery leadership — architecture runway, Design–Develop–Run, coaching leads and engineers through simplification under fire

Platform Architect at Careator Technologies, Sep 2021 - Dec 2023 · 2 yrs 4 mos, Bengaluru, Karnataka, India, Phase II of the Tesco order-platform arc — live AWS → Azure foundation for an estate at ~500M API hits/day. • Terraform/Ansible IaC, Azure landing zones, networking, PIM • EC2 / self-managed K8s → AKS; ECR → ACR; Kafka → Confluent Cloud (active-active); ES → ECK; Redis/Couchbase replatforms • Azure Data Factory for ~100B documents / ~100TB+ class archival paths • Jenkins → GitHub Actions + Argo CD / Argo Rollouts; consumer guidance for ~15 external Kafka teams • Zero-downtime cutover design: customer segmentation, anti-corruption routing, canary expansion Stints: Sep 2021 – Oct 2022 and Mar 2023 – Dec 2023.
