What I Use & Do
Since 2019, I've been building AI powered products, agentic AI systems, and full stack cloud-native services across fintech, Cloud and SaaS. My stack isn't just a list of tools it's shaped by 6+ years of shipping production systems optimized for latency, cost, and security.
AI & ML
Architecting agentic AI systems with agent orchestration, vector search, and tool calling to enable reasoning, planning, and self correction in production workflows.
Backend
Building high throughput backend services and APIs processing thousands of concurrent transactions with fault tolerance and regulatory compliance.
Cloud & Infrastructure
Designing cloud native architectures on AWS with containerized deployments, serverless workflows, and infrastructure as code for production grade reliability.
DevOps & Tooling
Streamlining delivery with automated pipelines, configuration management, secrets management, and GitOps workflows that cut costs and accelerate releases.

Summary
Experience
Lead Software Engineer (AI)
Jan 2021 — Dec 2025- Architected and productionized agentic AI systems using LangChain orchestration, vector search, and tool-calling for real-world workflows.
- Built scalable LLM pipelines with memory, caching, evaluation, and feedback loops optimizing latency, cost, and reliability.
- Integrated AI agents with data, APIs, and infrastructure (PostgreSQL, Redis, AWS) while enforcing security and observability.
- Developed asynchronous data ingestion and ML-triggered workflows processing 500+ messages per second.
- Built critical communication systems using AWS SES, SNS, Lambda, scaling to 10,000+ daily interactions.
- Created a secure internal CLI in Golang with HashiCorp Vault and ConsoleMe for 100+ internal users.
Software Engineer (Backend)
Jun 2021 — Jun 2023- Forward deployed by SudoConsultants to a US-based fintech company.
- Engineered RESTful APIs using Golang and MongoDB for seamless fintech integrations with full regulatory compliance.
- Integrated major payment gateways (Elavon, Cybersource, TSYS, Heartland, Shift4) with PCI-DSS compliant tokenization.
- Scaled the transaction pipeline to support tens of thousands of concurrent daily transactions with fault tolerance.
DevOps Engineer
Feb 2020 — Dec 2020- Introduced automation using IaC, Bash, and Ansible configuration management.
- Deployed two end-to-end microservice-based infrastructures on AWS with GitOps.
- Performed Elasticsearch cluster tuning, reducing production cluster cost by 30%.
- Managed infrastructure as code, container builds, and secrets management with Vault.
Software Development Engineer
Apr 2019 — Jan 2020- Developed three modules for network/systems monitoring to help customers achieve 99.9% SLA.
- Rewrote reporting API in Node.js with SQL optimization and caching, reducing response times from minutes to under 20 seconds.
- Implemented CI/CD pipelines with automated testing, rollback strategies, and environment-specific configuration.
- Designed an interactive dashboard with D3 and Vis.js, improving monitoring response time by 15%.
