--- ## Case Studies ### Mini Case Study: Replay-Safe HL7 v2 to FHIR Ingestion - **Problem**: ADT retries and out-of-order delivery produced duplicate encounters and noisy reconciliation queues. - **Method**: Implemented correlation IDs, idempotency keys, deterministic mapping rules, and replay-safe write guards with audit trails. - **Result**: Duplicate writes reduced by **~92%** in normalized replay tests, reconciliation exceptions reduced by **~28%**, and incident triage time reduced by **~35%**. ### Mini Case Study: Go Service Performance Tuning + SLO Protection - **Problem**: API p95 latency spikes during peak windows triggered SLO burn and on-call escalations. - **Method**: Profiled hot paths with `pprof`, reduced lock contention in critical handlers, tuned connection pooling, and added request-budget alerts tied to p95/p99 thresholds. - **Result**: p95 latency improved from **~210ms to ~120ms** and p99 from **~480ms to ~260ms** in normalized load tests | sustained throughput capacity improved by **~55%** and error-budget burn reduced by **~40%**. --- ## Articles - [How I Design Replay-Safe HL7 v2 -> FHIR Ingestion](/article-10) - [Go and Kubernetes: Building Cloud-Native Platform Tools](/article-6) - [Building Kubernetes Operators in Go](/article-4) - [Kubernetes Distribution Comparison Guide](/article-1) - [View All Articles](/articles) ### Publishing Cadence (Every 30 Days) - Publish one new engineering post every 30 days. - Next post: **FHIR IG validation + versioning in production** (target: 2026-04-08). - Following post: **Controller/operator safety patterns** (target: 2026-05-08). - Keep every post tagged with date + topic to make recency obvious for recruiters. --- ## Profile Sync Discipline - Any LinkedIn title or keyword change gets mirrored on this site the same day. - Quarterly review removes tooling/topics I no longer want inbound recruiter traffic for. - Selected Outcomes gets refreshed with current metrics after major deliverables. --- ## Contact If you're hiring for the target roles above, use the [contact form](/contact#recruiter-contact-form) or ping me on [LinkedIn](https://www.linkedin.com/in/egntuywbw001/). - Email alias: `hello [at] jagadesh [dot] dev` - LinkedIn: [linkedin.com/in/egntuywbw001](https://www.linkedin.com/in/egntuywbw001/) ## About # About Me ## Who I Am I am Jagadesh Ata, a Senior Kubernetes Platform Engineer (Golang/Python API) focused on healthcare interoperability. I build FHIR R4 APIs and HL7 v2 integration services that run on Kubernetes and remain reliable under production clinical workloads.

Choose the model that fits your hiring need—fractional staff engineer, project delivery partner, or long-term reliability coach. ### Go Codebase Assessment (2–3 weeks) **When to choose this:** you're inheriting or scaling a Go service and need clear priorities before investing further. **Deliverables:** - Static and runtime analysis covering architecture, concurrency, testing, and deployment posture - Profiling and benchmarking results with concrete remediation backlog - Kubernetes deployment review, resiliency scorecard, and observability gaps - Executive summary plus deep-dive walkthrough with your engineers ### Build & Ship Partnership (8–16 weeks) **When to choose this:** you need senior horsepower to deliver new Go capabilities while levelling up the team. **Deliverables:** - Feature or platform roadmap co-authored with product and engineering leads - Implementation of Go services, operators, or tooling with tests, docs, and CI/CD pipelines - Golden path improvements (GitOps, release automation, runtime dashboards) that stick after launch - Mentorship, pairing sessions, and hiring support for internal engineers ### Reliability & Coaching Retainer (quarterly) **When to choose this:** you already ship Go services and want an experienced partner watching performance, incidents, and roadmap risks. **Deliverables:** - Monthly production health reviews (latency, error budgets, cost) with action items - Architecture consults and design reviews for upcoming Go/Kubernetes projects - Incident retrospectives with systemic fixes, not just patches - Team enablement: workshops on debugging, observability, or controller design ## Working together - **Transparent cadence:** weekly updates, shared notes, and dashboards so stakeholders stay aligned. - **Code you can live with:** idiomatic Go, readable tests, and documentation that survives onboarding. - **Partnership mindset:** success is measured by your team moving faster and more confidently, not by billable hours.
