E Sai Krishna

Acting Team Lead architecting AI-native engineering workflows — from a production MCP server to agentic SDLC automation — while leading migration of legacy monolithic systems to high-performance microservices.

• ▸Architected and deployed a production MCP server exposing .NET codebase analysis as agent-consumable tools, with hallucination-resistant schemas, retry orchestration, failure containment, and CloudWatch invocation observability — adopted as the team-wide Claude Code standard
• ▸Lead migration of legacy monolithic systems to high-performance RESTful microservices, improving API response times and reducing technical debt across service domains
• ▸Built a RAG pipeline (ChromaDB) grounding SDLC agents in internal knowledge as part of a GenAI hackathon solution adopted by the product team; defined agent observability standards — CloudWatch tracing and quality gates in GitHub Actions CI/CD
• ▸Designed tool schemas, abstraction layers, custom skills, and slash commands — reaching AI Maturity Level 3 across the team
• ▸Mentor 11 engineers in .NET best practices, system design, and cloud-native development through weekly technical sessions and structured code reviews
• ▸Collaborate with clients and architects on AWS infrastructure evaluation and cloud-native solution design

Led design and zero-issue production rollout of a Hangfire-based workflow orchestration platform replacing a legacy batch system, with idempotency guarantees and real-time observability.

• ▸Authored the Batch Migration design document and led zero-issue production rollout of a Hangfire background job framework with configurable retry, idempotency guarantees, and failure containment
• ▸Investigated a WCF service outage blocking the Hangfire job queue; performed RCA and recommended a targeted revert that fully recovered production
• ▸Designed a high-throughput queueing system with retry policies, reducing job failure rate by 30% and eliminating manual intervention for 90% of failure scenarios
• ▸Implemented WebSocket-based real-time progress notifications replacing polling, reducing server load by 25% and delivering sub-500ms user feedback
• ▸Added build verification steps, Flyway DB migration checks in CI/Git hooks, and a release branching strategy using GitHub Actions
• ▸Refactored legacy ASP.NET applications applying SOLID principles, reducing average response latency by 20%

Authored the REST API modernisation design standard for the platform — deterministic contracts, versioning, and schema consistency — and resolved deep performance bottlenecks.

• ▸Authored a REST API modernisation design document with deterministic contracts, versioning, and schema consistency, targeting ~50% performance improvement; adopted as the team architectural standard
• ▸Performed deep performance profiling and root-cause analysis on complex .NET systems, reducing average page load time by 40%
• ▸Improved code quality standards by introducing .editorconfig conventions and Verify end-to-end integration tests, adopted across the platform
• ▸Evaluated AWS infrastructure configuration, recommending RDS optimisation and Lambda concurrency adjustments resulting in 20% cost reduction
• ▸Led cross-team architectural alignment sessions across ASP.NET, .NET Core, Angular, and PostgreSQL

Scaled the InsurTech platform through AWS re-architecture, microservices migration, and CI/CD adoption, driving a 60% revenue increase and 40% error reduction.

• ▸Proposed and implemented AWS infrastructure re-architecture resolving bulk quote conversion failures — directly contributing to a 60% revenue increase within two quarters
• ▸Pioneered CI/CD pipeline adoption using GitHub Actions across 5 services, reducing release cycles from 2 weeks to 3 days (50% efficiency gain)
• ▸Orchestrated migration from monolithic to microservices architecture with event-driven pub-sub communication, reducing system errors by 40% and improving fault isolation
• ▸Designed an automated batch job system replacing manual processes, saving the service team 2 full working days per week (104 days annually)
• ▸Built a DynamoDB-backed data access layer supporting high-throughput insurance transaction processing at 99.9% availability SLA
• ▸Mentored 5 engineers through structured code reviews and pair programming; 2 promoted to Senior level

Built core InsurTech platform capabilities — policy APIs, automated underwriting, and payment integrations — for a P&C insurance product.

• ▸Designed and built RESTful APIs for the Socotra Policy Administration System, enabling seamless data exchange across policy lifecycle stages
• ▸Implemented an automated quote pricing engine with underwriting approval logic, delivering decisions in under 5 seconds and reducing manual review effort by 80%
• ▸Prototyped and implemented a webhook-based payment flow decoupling order processing from payment execution, improving UX and system resilience
• ▸Integrated Stripe Payment Gateway supporting refunds, adjustments, and scheduled payments; authored API documentation for Stripe and third-party integrations
• ▸Optimised the document generation pipeline, reducing processing time by 5+ seconds per document for high-volume batch operations

Provided Tier-2 technical support for Google's DoubleClick for Publisher (DFP) platform, serving major enterprise clients.

• ▸Tier-2 technical support for enterprise clients (Microsoft, Motorola, Samsung, Apple)
• ▸Documented defects in JIRA and coordinated with engineering for resolution

Designed and automated regression test suites for a telecom CRM and order processing platform.

• ▸Designed and automated regression test suites using Selenium and NUnit in C#/.NET, improving regression coverage by 60%
