Work Experience

Middle Software Engineer - Full-Stack

Jul 2023 - Present
Spiraledge, Inc (Hybrid)
  • Microservices (.NET & NestJS): Designed/decomposed services by bounded contexts; DI-first, versioned REST, OpenAPI/Swagger, clear service boundaries.
  • Event-driven (RabbitMQ): Built pub/sub & work-queues with routing keys; idempotent consumers, retry/backoff, DLQ; transactional outbox for data/event consistency.
  • AI Agents & Automation: Implemented tool-using LLM agents to look up/summarize/update records across services; added validation, rate-limits, audit trails, and human-in-the-loop for low-confidence cases.
  • AI parsing & content: Converted semi-structured inputs → strict JSON with schema validators/fallbacks; automated accessibility content; FE consumption designed to avoid UX regressions.
  • Search & data: Elasticsearch (index/analyzers, query DSL, search_after, zero-downtime reindex); MongoDB + PostgreSQL/SQL Server (schemas, migrations, indexing, query shaping).
  • Frontend (Next.js/React): Shipped SSR-safe CRM/Admin UIs with typed forms, schema validation, accessible states, error boundaries, and defensive rendering.
  • Testing & test automation: Converted high-priority manual test cases → automated using Playwright (E2E) for CRM/Admin journeys; headless CI runs with reports/artifacts. Cypress (E2E smoke), Postman regression; contract tests for API clients.
  • Cloud & DevOps: Containerized services; AWS; CI/CD with GitHub Actions/GitLab CI.
  • Security: Applied OWASP controls (input validation, rate-limit, authZ policies); secret rotation & CI secret-scanning; coordinated pen-test fixes; standardized error taxonomy.
  • Third-party (summary): Shopify, Amazon SP-API, Walmart WFS, Attentive, Kustomer - AI agent/chatbot (integrations & API consumption).
  • Agile & leadership: Full Scrum cadence (planning/refinement/review/retro); partnered with QA/Product on DoD & acceptance criteria; mentored fresher engineers and facilitated weekly code reviews.

Junior Software Engineer - Full-Stack

Sep 2022 - Jun 2023
Spiraledge, Inc (Onsite)
  • Backend: REST endpoints with ASP.NET Web API & NestJS (controllers, DTO validation), OpenAPI/Swagger; consistent error model.
  • Queues: RabbitMQ for small background tasks; basic retry/backoff & DLQ; logged processing results for debugging.
  • Data modeling: simple MongoDB collections & SQL schemas; added index/pagination; small migrations.
  • Frontend: React/Next.js pages (auth, forms, tables); controlled forms with validation; SSR-safe data fetching.
  • Testing & CI: Cypress/Playwright smoke for login/CRUD; Postman runner; GitHub Actions/GitLab CI (build/test/lint).
  • Cloud & security: exposure to AWS S3/CloudWatch logs; minimal-privilege IAM; OWASP basics (input validation, CORS, rate-limit).
  • Agile: stand-ups and planning.

  • HTML/CSS/JS: semantic pages, forms, DOM events, mobile-first layouts.
  • React basics: small SPA consuming REST endpoints.
  • WPF (.NET, Prism/MVVM): device-management UI (USB), configuration screens, persisted settings.
