Alvin Radeka Pratama

• Freelance software engineering engagements across backend and full-stack work.
• Hands-on exploration of AI-assisted and agentic development workflows, continuing the AI-augmented engineering practice started at Halodoc.

• A planned pause to focus on family and personal matters, and to get hands-on with the shift in how software gets built, studying modern AI-assisted and agentic development.

• Launched FitScore, a feature quantifying users' health conditions, adopted by ~5% of Halodoc users (tens of thousands of people) and seeding a multi-year product roadmap built around it.
• Designed and shipped an extended, multi-doctor chat system on existing infrastructure, lifting session-length limits and enabling collaborative patient care, used by 5,000+ users.
• Introduced an AI-augmented PRD analysis workflow, taking the team from manual feasibility scans to working prototypes before a line of production code.
• Mentored a team of 10 engineers and SDETs through structured technical guidance, performance reviews, and career development planning.
• Monitored and resolved user tickets and complaints, maintaining 100% SLA compliance.

• Led the migration of microservices from Node.js + MongoDB to Go + MySQL (architecture, migration strategy, business continuity plan, and disaster recovery framework), consolidating 14 services into 6 and roughly halving estimated infrastructure cost.
• Mentored and guided a team of five engineers running AnekaPay's core systems, ensuring reliability and scalability.
• Acted as technology consultant, assessing feasibility of new business ideas and expansions, aligning technology with business goals.

• Grew the engineering organisation from 3 to 25 engineers across multiple teams: hiring, org structure (three team leads and a principal engineer reporting in), and a culture of autonomy and shared knowledge.
• Designed a metrics-driven performance-review framework (story points, rework rate, deployment success, code reviews, technical debt, innovation). Zero complaints across two years, with transparent dashboards and no review-time surprises.
• Led ISO 27001 gap remediation across all Delos Aqua departments: partnered with external auditors, identified gaps, and drove fixes company-wide.
• Stood up data governance covering structure, storage safety, and accessibility across the organisation.

• Hired to build the team from the ground up, grew it from 3 to 12 engineers across Indonesia, India, and China, running hiring end to end.
• Personally architected the integration layer between Shipper's WMS and Honeywell's inventory and fulfillment platform; led the single-warehouse POC and gradual rollout to 3–5 live warehouses at 99.99% uptime, within a ~300-warehouse network moving 40–60k orders/day.
• Led the China-based sub-team that reverse-engineered and modified Honeywell's WMS directly, working across languages and companies.
• Delivered on time despite constantly churning integration contracts and APIs: aggressive scoping, incremental versioning, gradual rollout.

• Owned the subscription system: took over an intern-built MVP and revamped it end to end (backend and UI, with frontend and design). Daily payment success rose 3–4×, from under 10% to 30–40%, with test coverage pushed to 85%.
• Integrated OVO as a subscription payment method as it became Tokopedia's primary wallet; eliminated internal server errors with systematic retries; shipped payment-expiry notifications and top-up nudges.
• Tribe champion for the org-wide canary deployment rollout: documentation, knowledge transfer, and deployment monitoring across every squad in the tribe.
• Initiated Monitoring-as-Code (versioned Grafana dashboard configs); authored the onboarding curriculum for new backend engineers. Promoted to Senior.

• Full-stack development on Java and Kotlin across three legacy enterprise systems, including a logistics/warehouse system serving ~100 users, with 200–300 enterprise users in total at ~95% uptime.
• Drafted the team's DevOps adoption plan (Jenkins, rolling deployments, protected branches, enforced pull requests and unit tests) to replace fully manual deployments.
