ATS score and CV checks

ATS Score 98%

How we calculate this score

  • Keywords: 60% of the total. AI extracts keywords from your job description. If you do not provide one, a standard job description for the title matching your CV is used. This is not a match to a specific vacancy.
  • Text-based CV: 20%. The text CV assessed here receives 100 for this part.
  • CV quality: 20%. We start at 100 and subtract points for issues found by our CV checks, down to a minimum of zero.
  • Keyword coverage = round(100 × confirmed matches ÷ total keywords). Exact matches and supported equivalents verified by AI receive full credit; unsupported keywords receive none. Live text checks use the saved equivalents and do not request a new AI review. Without keywords, no overall ATS score is available.
  • Final score = 60% of keyword coverage + 20% of the text score + 20% of the quality score, rounded to a whole number. Without keywords, no overall ATS score is available.

What this score means

Our scores are estimates, not employer ratings. They may contain errors and do not guarantee accurate parsing, a ranking, an interview, or a job. Check your document against the employer’s requirements. You are responsible for relying on this score.

SUMMARY
High-performance Java engineer with 10 years of experience building low-latency trading and market-data services. Develop high-throughput, concurrent systems for agency liquidity and Principal Risk, working with engineering, trading and risk colleagues on releases across EMEA and the US. Apply JVM tuning, garbage collection optimisation and memory profiling to identify performance constraints, then validate changes through testing and production diagnostics. Recent platform development has included event-driven services, Aeron messaging and low-level Java integrations, with shared memory and memory-mapped files used in performance testing. Earlier contributions span reactive processing, TCP/UDP networking and Linux systems, providing a practical background across the trading platform stack.
EXPERIENCE
High-Performance Java Engineer
May 2025 - Present
Ternion Trading Systems
London
Develop event-driven Java services for agency liquidity and Principal Risk workflows, shaping throughput and latency requirements with engineering, trading and risk colleagues.
Deliver EMEA and US project changes with CRB stakeholders, using load tests and production telemetry to verify behaviour across regional trading flows.
Profile JVM performance and tune garbage collection strategies, heap use and thread scheduling, resolving latency spikes before release.
Apply Java Unsafe and JNR-FFI at carefully isolated boundaries for selected high-frequency operations, documenting safety constraints and validating results against Java implementations.
Use Aeron messaging, shared memory and memory-mapped files in a low-latency prototype, measuring throughput and tail response times against the existing service path.
Senior Java Engineer
Jan 2022 - Apr 2025
Harbourlight Securities
London
Reworked a multi-threaded order-routing service into clearer event-driven components, applying concurrent programming patterns to reduce contention during market bursts.
Introduced Aeron for a latency-sensitive internal messaging path in 2023, comparing delivery behaviour and throughput with the prior messaging approach under repeatable test loads.
Used memory profiling and fine-grained JVM tuning to identify allocation pressure and GC pauses, then verified improvements through sustained performance tests.
Built JNI integrations for a native market-data decoder and assessed CPU architecture effects, keeping shared-memory access and memory-management risks within documented controls.
Improved operational diagnosis by correlating application traces with Linux kernel and memory-management indicators during performance investigations.
Software Engineer
Jul 2019 - Dec 2021
Calder Financial Technology
Cambridge
Delivered Java services for electronic trading and liquidity reporting, using reactive and event-driven design to process market updates without blocking downstream consumers.
Implemented low-latency socket programming over TCP/UDP and investigated protocol behaviour under simulated packet loss and burst traffic.
Applied data structures and algorithms to market-event handling, documenting complexity trade-offs and validating performance through repeatable benchmarks.
Used Java Unsafe for a narrowly scoped buffer-management component after profiling identified copying overhead, adding focused tests to protect memory access assumptions.
Java Developer
Sep 2016 - Jun 2019
Juniper Exchange Systems
Edinburgh
Built Java components for exchange connectivity and market-data processing, developing a practical foundation in concurrent programming and JVM behaviour.
Traced response-time variation through thread and heap profiling, then improved a parser's allocation patterns and recorded the results for code review.
Worked with Linux-based test environments to examine TCP/UDP traffic, socket behaviour and memory use during simulated trading sessions.
Created unit and integration tests for event-driven processing, using core data structures and algorithms to keep message handling predictable as test volumes grew.
LEADERSHIP, AWARDS & RECOGNITION
Mentored two graduate engineers in JVM profiling, concurrency debugging and production diagnostics during 2024.
Recognised by the engineering team in 2023 for clear performance-test documentation used across multiple service releases.
