Marketplace Platform & AI Automation

Backend Developer

MDigital / MMarket ecosystem 2026 — Present

Working on marketplace services across backend, platform delivery and AI-powered catalog automation. Main areas: Go microservices, Kafka/outbox workers, PostgreSQL, Kubernetes deployments, GitLab CI/CD, Qdrant vector search, LLM-based category/attribute mapping and internal QA tools.

  • Contributed to splitting marketplace microservices into separate Kubernetes workloads: API, worker and outbox-worker, isolating HTTP traffic from background processing.
  • Added backward-compatible runtime modes in Go services, allowing workers and outbox relay processes to be controlled through CLI commands and environment flags.
  • Coordinated GitLab CI/CD, Rancher rollout checks and DevOps handoff for Kubernetes, Helm/ArgoCD, service routing, labels/selectors and secret injection changes.
  • Built AI-assisted category and attribute mapping pipelines using LLMs, Qdrant semantic search, Kafka workers, confidence scoring, post-processing and production safety checks.
  • Prepared large-scale catalog backfills and QA artifacts for marketplace products and attributes.
  • Diagnosed deployment and PostgreSQL migration issues using schema checks, temporary Kubernetes jobs, safe migration metadata repair and post-deploy smoke checks.

Software Developer Intern

MBank / MMarket ecosystem Winter 2025–2026

Worked on backend services in a large digital banking and marketplace ecosystem.

  • Contributed to backend services and product workflows in a fintech/marketplace environment.
  • Worked with Python/FastAPI/PostgreSQL-based backend development.
  • Learned production constraints around reliability, data correctness, security and releases.
