Detail per Option

SCOPE: Membangun API Gateway terpusat dan mengekstrak Auth Service dari PHP monolith SIAKAD ke Go microservice standalone.

WHY THIS FIRST:

API Gateway = foundation untuk SEMUA microservices lainnya
Auth Service = most independent module, lowest risk to extract
Enables incremental migration (Strangler Fig) tanpa breaking change

Final Deliverables:

📦 Go Auth Service (production-ready, deployed to EKS)
📦 API Gateway configuration (Kong/Traefik)
📦 Helm charts + CI/CD pipeline (GitHub Actions)
📦 Test suite (unit + integration + load)
📦 Architecture Decision Records (3-5 ADRs)
📦 Runbook + monitoring dashboards
📦 Knowledge transfer recordings

SCOPE: Mengekstrak modul Payment Gateway dari SIAKAD monolith ke Go microservice standalone dengan ACID compliance penuh.

WHY THIS:

Payment = highest-risk module (uang mahasiswa)
ACID compliance wajib — satu error = reputasi hancur
Bounded context yang jelas (payment ≠ academic)
Pengalaman banking backend (BTPN 4.1M users) = direct match

Final Deliverables:

📦 Go Payment Service (production-ready, ACID-compliant)
📦 Bank integration adapters
📦 Reconciliation engine
📦 Audit trail system
📦 PCI-DSS compliance documentation
📦 Financial accuracy reports
📦 Monitoring dashboards + alerting

SCOPE: Membangun dedicated KRS Service yang menyelesaikan race condition saat mahasiswa berebut kursi kelas secara serentak.

WHY THIS:

Masalah #1 yang dirasakan mahasiswa setiap semester
Race condition = core engineering challenge
Go goroutines + Redis distributed locking = perfect solution
High-visibility win: kalau ini solved, kampus notice immediately

Final Deliverables:

📦 Go KRS Service (production-ready)
📦 Redis distributed locking system
📦 Waitlist engine
📦 Real-time seat availability dashboard
📦 Load test results + benchmark report
📦 KRS season operations runbook

Subject: Proposal: 3-Month Microservices Contract —
         with prototype + technical audit

Hi Shafa / Tim Engineering SEVIMA,

Saya tertarik dengan posisi Freelance Software Engineer
(Microservices). Daripada hanya mengirim CV, saya sudah
melakukan research mendalam dan menyiapkan beberapa
deliverables:

🎬 TECHNICAL AUDIT (5 min Loom):
Analisis arsitektur SEVIMA + rekomendasi microservices
migration path menggunakan Strangler Fig pattern:
[link Loom]

🔗 PROTOTYPE:
Go microservice boilerplate untuk EduTech domain —
clean architecture, gRPC, Docker, unit tests — siap
dipakai di hari pertama kontrak: [link GitHub repo]

📋 PROPOSED SCOPE (pilih 1 dari 3 opsi):
→ Option A: API Gateway + Auth Service extraction
→ Option B: Payment Service extraction dari SIAKAD
→ Option C: KRS Race Condition Solver (Go + Redis)

Setiap opsi mencakup:
Month 1: Design + implementation + TDD
Month 2: Integration + load testing
Month 3: Deploy to EKS + documentation + knowledge transfer

📊 TRACK RECORD:
→ Solo-built banking backend: 4.1M users, 30 days (BTPN)
→ IoT telemetry platform: 50K events/sec (Petrosea)
→ Multi-site fleet management: autonomous edge (HPU)
→ Full case studies: news.faisalaffan.com

Tech: Go • gRPC • Kafka • Docker • Kubernetes • AWS

Saya bisa mulai ASAP. Sebagai engineer yang terbiasa
solo-building at scale, saya self-directed dan
deliverable-focused. Anda hanya perlu define the problem —
saya deliver the solution + documentation.

Happy to discuss via 30-min call.
