VulnFlow
Reliable processing
190 findings returned through paginated results; replaying an accepted event preserved one terminal result, while a controlled retry reached the DLQ and recovered through a reviewed redrive.
Backend · Cloud · Platform
Systems that keep moving under load.
I build backend and cloud systems for work that cannot be left to chance: events that must not be lost, workloads that must recover, and data flows that need to remain understandable as they grow.

Personal project
BenchLab
Queue-backed benchmark execution with isolated multi-language workers.
Focus: RabbitMQ-backed workers execute language-specific containers and return authenticated results.

Data platform
JobRadar
Multi-source ingestion, normalisation, deterministic scoring and content-hash deduplication.

Case-study evidence
Proof behind the architecture.
Historical, sanitized evidence from controlled runs; no live telemetry or private data is exposed here.
BenchLab
Isolated execution
Queue-backed execution keeps long-running work outside the API, with language-specific containers and an authenticated callback boundary.
Attack Surface Mapper
Discovery pipeline
Tested Python workflow for discovery, validation, correlation and reporting, with evidence-aware scoring and structured outputs.
JobRadar
Deterministic ingestion
Multi-source ingestion with reliable adapters, explainable ranking and content-hash deduplication.
Professional experience
Current role
Junior Software Developer
Develop Java/Spring Boot backend services and REST APIs for production applications; contribute to database operations, CI/CD and deployment; and work directly with clients to clarify requirements and validate delivered solutions.
Direction
Build for the failure path, not just the happy path.
I want to work on cloud platforms that process large volumes of data without becoming fragile or opaque. That means thinking about throughput, recovery, observability, cost and security from the first design decision—not adding them after the system is already in production.
My focus is backend, cloud and platform engineering: the infrastructure and services that let product teams move quickly while the system remains reliable when traffic, data and operational pressure increase.
