Project details
Are slow queries, failing stored procedures, or deadlocks bottlenecking your applications?
I am a Senior Solution Architect with hands-on database engineering experience across Oracle, PostgreSQL, MS SQL Server, and MySQL. What sets me apart is enterprise-grade rigor combined with direct, hands-on execution: I do not just offer high-level advice; I fix root-cause bottlenecks directly in the code.
What sets this project apart:
Root-Cause Query Tuning: Refactoring inefficient SQL, eliminating full-table scans, and optimizing execution plans (EXPLAIN/ANALYZE) for instant latency drops.
Complex PL/SQL & Logic Fixes: Debugging stored procedures, packages, functions, and transaction locks with clean exception handling.
Zero Production Risk: Every fix is tested and verified on isolated/sample datasets with regression checks before release.
Documented Value: You receive fully commented SQL scripts, index recommendations, and before-vs-after performance benchmarks.
Whether you need a single slow query fixed or a full stored procedure tuned, I deliver fast, production-ready results.

About Krishna
Agentic AI Engineer | Solution Architect | Principal Backend Engineer
New Delhi, India - 1:13 am local time
I am a Senior Solution Architect and Backend Specialist with 20 years of hands-on enterprise engineering experience. I build reliable, fault-tolerant systems, ranging from stateful Multi-Agent AI workflows (LangGraph, MCP, RAG) to scalable cloud-native microservices (Java, Spring Boot, Python, AWS, Kafka).
How I can help your project:
1. Agentic AI & LLM Systems:
• Multi-agent workflows using LangGraph, Python, and State Machines.
• Zero-Trust AI boundaries via Model Context Protocol (MCP) and Pydantic Guardrails.
• Hybrid RAG pipelines with Qdrant vector search and Cross-Encoder re-ranking.
• Production safeguards: Log PII scrubbing (Presidio), prompt injection mitigation, and Human-in-the-Loop approval gates.
2. Backend Engineering & Cloud Infrastructure:
• High-performance microservices with Java, Spring Boot, Node.js, and FastAPI.
• Event-driven architectures using Apache Kafka and AWS messaging.
• Database performance tuning across PostgreSQL, Oracle, and SQL Server.
• Cloud deployments on AWS, Docker, and Kubernetes (EKS/RBAC).
3. SRE, Observability & Platform Stability:
• Incident triage automation and MTTR reduction.
• Full-stack observability: OpenTelemetry (OTel), Prometheus, Grafana, and Alertmanager.
• Architecture audits to eliminate production bottlenecks and SLA breaches.
Proven Track Record:
• Architected AutoResolve: An open-source autonomous SRE platform using multi-agent LLM workflows to automate L1/L2 alert triage and GitOps remediation.
• Eliminated a 200+ production incident backlog within 60 days for a global supply chain platform, achieving zero production incidents.
• Successfully modernised enterprise monolithic systems into high-velocity microservices ecosystems.
Whether you need a full AI agent pipeline built, an API bottleneck resolved, or an architecture audit, let’s connect and review your technical requirements.

Steps for completing your project
After purchasing the project, send requirements so Krishna can start the project.
Delivery time starts when Krishna receives requirements from you.
Krishna works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Root Cause Analysis
I examine the failing SQL/PL-SQL code, review execution plans (EXPLAIN/ANALYZE), analyze table indexes, and isolate bottlenecks, locks, or syntax bugs.
Query Refactoring & Code Patching
I refactor inefficient queries, rewrite PL/SQL procedures, add optimized indexes, and fix logical errors with clear inline documentation.
