Work Experience

Kollect System Sdn Bhd

Java Developer, AI Engineer & Team Lead

Aug 2025 – Present | Kuala Lumpur

achievements.sh

Built Kollect AI ETL from scratch — a production ETL platform using Java 21, Spring Boot 3.4, PostgreSQL, and clean architecture with adapter SPI pattern (CsvFileAdapter, JdbcDatabaseAdapter, RestApiAdapter), supporting DB-to-DB and CSV-to-DB data pipelines for ERP and Banking clients

Refactored monolithic ETL into 6-module Maven architecture with 30+ reusable workflow components, PostgreSQL COPY streaming (10K+ rows/sec), event-driven orchestration — processing 1.5M+ SAP records monthly at 99.8% success rate

Architected Spring Boot WebFlux gateway within a 4-service microservices architecture — JWT authentication, AES-256-GCM encryption, REST API routing, 5-layer Redis caching, and Docker containerization serving Banking, ERP/POS, and Collections domains

Implemented SpecKit-driven development with clean architecture and SOLID principles — feature specifications auto-generate implementation plans, driving 25+ custom pipeline components with real-time WebSocket (STOMP) execution monitoring

Led and mentored a team of 7 developers — conducting code reviews, establishing Git workflows and branching strategies, CI/CD pipelines, and guiding junior engineers through Agile/Scrum sprints from design through production deployment

Engineered high-performance data layer with PostgreSQL query optimization across 50+ tables, Redis caching strategy, Prometheus metrics export, and Docker Compose orchestration for multi-service deployment

Kollect AI ETL — Enterprise Data Pipeline Platform

Java 21Spring Boot 3.4PostgreSQLClean ArchitectureSpecKitOllama AIWebSocketSvelteKit 5

project-features.sh

$Built from scratch — production ETL platform using Java 21, Spring Boot 3.4, and clean architecture with adapter SPI pattern, supporting DB-to-DB and CSV-to-DB pipelines for ERP and Banking clients
$Spring Boot backend with pluggable adapter SPI (CsvFileAdapter, JdbcDatabaseAdapter, RestApiAdapter) — SOLID principles, schema validation, type compatibility checks, and connection validation engine
$AI auto-mapping via local Ollama LLM — analyzes source schemas and target database tables, suggests field mappings at 90%+ confidence with direct-load fan-out to 8+ target tables
$SpecKit-driven development — feature specifications auto-generate implementation plans and task lists, with acceptance scenarios driving 25+ custom pipeline components
$2-level orchestration system — Level 1: individual pipeline designer with 25+ node types, Level 2: workflow orchestrator composing pipelines into dependency-ordered batches
$Real-time WebSocket (STOMP) execution monitoring with state machine (INIT → STAGING → TARGET → SUCCESS), per-node timing, row counts, and millisecond-precision audit trails

Architecture Highlights

▼

• Spring Boot 3.4 backend with adapter SPI pattern: CsvFileAdapter, JdbcDatabaseAdapter, RestApiAdapter — pluggable source/destination system following clean architecture

• Java 21 with SOLID principles, OOP design patterns, and multi-module Maven project structure

• SvelteFlow (@xyflow/svelte 1.5) with 25+ custom node types: control flow (START, END, IF_ELSE, PARALLEL), sources (CSV, Database, API), transforms, destinations, and observability nodes

• 5-step Smart Flow Wizard: Source selection → Column analysis → Target discovery → AI mapping preview (confidence scores) → Confirmation and apply

• AI mapping cache (24h TTL) with multi-model support: Qwen3:8b for fast mapping, Qwen3:30b for deep analysis, name-similarity fallback when AI unavailable

• Connection validation engine: type compatibility checks, acyclic graph enforcement, port matching (RECORD_STREAM, FILE_STREAM, EXECUTION_CONTEXT)

• WebSocket (STOMP) real-time execution logs with state machine: INIT → FILE_PROCESSING → STAGING → TARGET → ARCHIVING → SUCCESS

• PostgreSQL schema design with migrations, query optimization, and comprehensive data validation pipelines

KollectGPT — Multi-Agent Text-to-SQL AI Platform

Spring Boot WebFluxJavaPythonFastAPILangGraphRedisPostgreSQLDocker

project-features.sh

$4-service microservices architecture — Spring Boot WebFlux gateway (JWT + AES-256-GCM encryption), FastAPI AI backend, SvelteKit 5 client + admin, Docker containerization
$Enterprise AI platform serving Banking, ERP/POS, and Collections domains — natural language to SQL across 50+ tables with sub-second response times
$Multi-agent ReAct architecture (LangGraph) with dynamic tool registry (30+ tools) — agents reason, call tools, observe results, and iterate until the answer is complete
$5-layer caching strategy with Redis — Schema singleton, Query cache, Semantic cache, Redis sessions, FAISS vector index for sub-second responses across 500+ columns
$Schema RAG pipeline with FAISS embeddings + FK graph traversal for automatic multi-table join detection and intelligent schema discovery
$ML pipeline: XGBoost for payment prediction, scikit-learn for risk profiling, Prophet for time-series forecasting, spaCy for NLP context extraction

Architecture Highlights

▼

• Spring Boot WebFlux gateway — JWT authentication, AES-256-GCM datasource encryption, REST API routing, rate limiting, audit logging

• Database-driven domain adapters — each domain (Banking, ERP/POS, Collections) has custom system prompts, tools, glossary, metrics, and followup patterns

• Zero-hardcoding tool registry loaded from database — tools filtered at runtime by domain type, schema validation, and feature flags

• Dual-path query engine with 4 migration modes (off → shadow → partial → full) — shadow mode comparison in production without user impact

• Conversation memory (Redis) with 10+ turn context preservation, entity tracking, pronoun resolution, and semantic follow-up query optimization

• Multi-provider LLM abstraction: OpenRouter, Ollama (air-gapped), OpenAI, Claude — with circuit breaker failover and automatic fallback

• Security: SQL injection prevention, read-only enforcement, Docker isolation, Prometheus metrics export

• Monitoring: shadow mode comparison dashboard, slow query detection, cache hit/miss tracking
