.NET and distributed systems · AWS · technical leadership
I have spent 9+ years building and modernizing enterprise backend systems in C#, .NET, AWS, Kafka and Kubernetes. I lead an 11-engineer team delivering cloud-native, event-driven services for a critical communications platform, and I built and launched TailorlyRemote, an AI-assisted job-matching platform that is live in production.
Crisis24 (OnSolve): leading the move from monolith to microservices
Technical lead for Team Titan (11 engineers) on the phased modernization of a Java monolith into .NET microservices on AWS EKS and Kafka. The platform supports 3,500+ organizations, nine notification modalities, a 99.99% availability SLA, and up to 150K notifications in five minutes.

Jul 2022 – Present · RemoteMemory and scalability
20 → 12 pods · memory ~90% → ~36%Diagnosed high-memory analytics and reporting workloads and reduced buffering with streamed HTTP response processing, cutting the deployment by 40% at comparable throughput.
Reusable messaging libraries
Up to 1.5K requests/sec per podBuilt shared Kafka consumer and resilience libraries for bounded concurrent processing, retries and reliable event handling. Adopted by multiple services: 5 Kafka consumers and 12 resilience-library consumers.
Throttling and backpressure
~1,000 requests/sec sustainedDesigned SQS-backed asynchronous HTTP delivery with Valkey-based distributed rate limiting, controlled retries and dead-letter queues to handle downstream 429 responses.
Billing correctness
Billed units down 26% · 36% · 41%Found duplicate billing records caused by concurrent scheduled and consumer processing, then added deduplication and concurrency safeguards. Audit queries and reconciliation reports showed billed units falling 26% (emergency minutes), 36% (SMS) and 41% (general minutes, one affected organization).
Exports
150 MB → 500 MB (~3.3x)Modernized the legacy export system to support larger output within the same three-minute processing window.
CI/CD and reliability
GitLab · SonarQube · Veracode · HelmHelped establish automated build, test, SonarQube and Veracode gates and Helm deployments to EKS. Troubleshot production incidents using Datadog, OpenSearch, CloudWatch and Kubernetes diagnostics.
Architecture and delivery
Billing · analytics · exports · self-registrationLed technical design and development across billing, analytics, exports, self-registration and HTTP integrations. Defined API contracts, reviewed solutions, estimated epics and coordinated cross-team dependencies.
Leadership and mentoring

TailorlyRemote: remote job discovery and résumé tailoring
An AI-assisted application that finds remote jobs open to candidates in India and tailors a Word résumé to each job without breaking its formatting or inventing claims. Founder and sole engineer; live in production.
- Product and architecture. Designed, built and launched the application with .NET 10, React and TypeScript, PostgreSQL and Hangfire, a modular architecture and design documentation that includes 12 architecture decision records.
- AI with document integrity. Provider-agnostic LLM integration with model routing and structured output validation. OpenXML is used to edit .docx résumés in place, preserving formatting, with checks that block unsupported claims. The model returns edits only, and every change is a diff the user approves.
- Engineering and security. Automated tests, GitHub Actions, a typed OpenAPI client, authentication, rate limits and structured logging.
- Production deployment. AWS EC2 running Docker Compose behind Caddy with automatic TLS, access through Session Manager with no SSH, encrypted nightly PostgreSQL backups to S3, and email through AWS SES.
