I design backend workflows, test software deliberately, and document biomedical research through structured methods, measurement, and evidence.
Email meBackend engineering, QA, workflow automation, and biomedical research.
Backend systems and test workflows built around structured data, deterministic processing, quality gates, and clear documentation.
Graduate research and laboratory experience grounded in biomaterial processing, measurement, characterization, and SOP-led practice.
Backend systems, workflow automation, and independent QA case studies with supporting evidence.
A backend workflow for turning structured job information into traceable application materials.
Implemented ingestion, normalization, persistence, workflow-state processing, API endpoints, CLI tools, project-state logs, and evidence-grounded document generation.
Verification controls and quality gates were used to keep processing deterministic. Broader work includes more than 1,000 automated pytest test cases, with workflow fixes involving item-linking and URL collisions.
A workflow for collecting and preparing job applications across multiple sources.
Built collection, normalization, filtering, deduplication, LLM matching, tailored CV and cover-letter generation, storage, and notifications across 5 sources and 8 countries.
Jobs move through collection, normalization, matching, document generation, storage, and notification stages. No application outcomes or employer relationships are claimed.
Independent regression and stability testing of an iOS retail application on iPhone and iPad through TestFlight beta access.
Covered permissions, merchandising, carts, discounts, draft orders, cash and card payments, returns, partial refunds, receipts, and analytics.
59 unique test cases were organized across Merchandising and Orders boards, Store Manager and Sales Associate roles, 236 total runs per shift, standardized 11-column bug reporting, surface mapping, user attribution, and priority categories.
API test design, execution, and documentation for a defined Reqres scope.
Used Postman and Swagger/OpenAPI to document 12 test cases: 9 Pass, 0 Fail, and 3 N/A.
A bug-report sheet recorded no defects in the executed scope. This is not a claim that the API is universally bug-free.
Independent exploratory QA case study of a browser-based registration workflow.
Applied boundary-value, equivalence-class, state-transition, negative, validation, accessibility, DOM/source, network, browser comparison, and repeatable browser automation techniques.
Findings included validation and messaging inconsistencies, redirect behavior, password exposure in URL parameters, required-field and email validation gaps, password mismatch acceptance, accessibility association, whitespace and long-input handling, repeated submission, and keyboard/input-path behavior. The private assessment URL is intentionally omitted.
Structured functional and compatibility testing across authentication, sessions, validation, security scenarios, and browsers.
Covered Chrome, Edge, and Firefox, including negative login, required fields, masking and case, forgot password, logout, navigation, boundary cases, SQL injection/XSS scenarios, keyboard accessibility, HTTPS checks, performance checks, and rapid repeated clicks.
50 test cases were executed: 50 Pass, 0 Fail, and 0 N/A. No defects were identified within the documented scope. Demo credentials are not published.
Graduate research in Smart Biomaterials and Applications, supported by documented methods and research outputs.
A two-stage study comparing bacterial cellulose scaffolds with electrospun fish-gelatin scaffolds.
Prepared electrospun fish-gelatin membranes, stabilized them with glutaraldehyde crosslinking before mineralization, and measured mineral uptake gravimetrically after five alternating immersion cycles using CaCl2 and Na2HPO4.
Work included experimental design, measurement, biomaterial processing, SEM and ATR-FTIR findings documentation, four technical reports, and dissertation work. Supporting research outputs are available through the presentation link below.
Methods & Equipment: CaCl₂ (0.5 M) mineralization bath, Na₂HPO₄ (0.3 M) mineralization bath, glutaraldehyde (1%) in ethanol as crosslinker, analytical balance, magnetic stirrer, and drying chamber.
Professional laboratory roles that shaped a careful approach to records, procedures, and biosafety.
Akim Police Clinic
Processed 15+ clinical specimens daily, with data entry, record management, SOP adherence, and biosafety procedures.
LUTH Chevron Molecular Biology Research Laboratory
Centrifugation, aliquoting, cryovial labeling, PCR preparation, agarose gel work, and GLP/biosafety practices.
Tools and methods used across the two tracks.
Formal study across biomedical engineering, biochemistry, and backend software engineering.
