Abraham Babalola

Systems & Security Engineer

I break complex systems down to first principles. Most of my work lives at the intersection of data systems, web security research, and building low-latency software that does one thing reliably without bloat.

Systems & Research

Dynamic project cards with interactive architecture and engineering trade-offs.

Quantitative Systems & Risk

EdgeRunner

</> Source

Automated market discovery and historical edge-matching pipeline built to enforce mathematical discipline and bankroll protection in fast-moving markets.

Automated pipeline comparing live market odds against historical edge distributions to discard low-conviction plays before execution.

Execution Modes: Offline mock settlement, dry-run validation, and live adapter
Market Discovery
Edge Matcher
Risk Controls
Settlement

Synchronizes cross-league timing and combines candidate tickets across multiple rounds into a master board.

Circuit Breakers: Hard exposure constraints and automated abort triggers halt candidate execution under defined adverse loss conditions to protect capital.

Application Security & Fuzzing

Input Mutator

</> Source

Constraint-guided permutation engine producing structured, parser-aware mutations to uncover WAF bypasses and proxy/backend normalization desync.

Instead of blind byte fuzzing that gets rejected at the network edge, it understands grammar and encoding layers to test whitelist boundaries and blacklist evasion.

Testing Intents: Whitelist probing, blacklist evasion, and proxy differential gaps
Target Input
Character Mutation
Representation
Transport Encoding

3-stage composition pipeline exploiting Unicode normalization, overlong UTF-8, radix variation, and delimiter ambiguity.

Deployment: Single fat JAR running as a native Burp Suite tab, a desktop GUI with a live normalization inspector, and a headless CLI pipeable to wordlists.

Market Intelligence & Consensus

Forecast Hub

</> Source

Business intelligence pipeline clustering live contracts from Polymarket and Kalshi to isolate capital-backed consensus and expose cross-platform divergence.

Filters out meme-coin speculative noise, normalizes disparate exchange schemas, and aligns identical targets side-by-side to flag real operational risk when market consensus splits.

Persistence: SQLite in WAL mode (sub-millisecond reads, zero-lock concurrency)
HTTP/2 Streams
Noise Filter
Two-Tier Matcher
SQLite WAL Storage

Deterministic event clustering without heavy vector search dependencies. Guardrails prevent parameter mismatches (e.g. 2% vs 3% strikes).

Deliberately Lean: No microservices circus or cloud DBs. Concurrent HTTP/2 reads coupled with local SQLite WAL provided instant queries without network overhead.

Edge Runtimes & Distributed State

Cloudflare Edge AI Twin

</> Source

Stateful conversational twin service deployed on Cloudflare Workers using Durable Objects over WebSockets with an automatic multi-model failover chain.

Powers the live interactive widget on this site. Manages session lifecycles, per-IP rate limiting, and privacy-preserving audit logs via salted SHA-256 IP hashing on D1.

Latency Impact: -200ms TTFT reduction & zero factual hallucinations

The RAG Decision: Prototype ran classic Vectorize embeddings + top-k retrieval. Cosine similarity over 3 chunks missed basic facts and burned 2x inference quota. Replaced with distilled in-memory context: 100% accuracy, half the neuron burn.

Resilience: Automatically cascades across 4 models (Llama 3.1 8B → Llama 3.1 8B Fast → Llama 3.2 3B → Mistral 7B) to guarantee uptime during upstream provider rate limits.

Data Analysis & Econometrics

Zara Product Economics

</> Source

Commercial data audit of 20,000+ SKUs. First question was whether the public dataset could be real — it could not. Then a Negative Binomial GLM on what remained, with volume lift converted into a margin decision.

Refused the standard Kaggle ML story. Sales volume is artificially bounded (518–1,940), merchandising uses grocery labels on an apparel catalog, and sourcing-country means are indistinguishable from noise.

Audit: Synthetic DGP · promotion IRR 1.59 · lift fails a margin test

GLM, not vanity lift: Negative Binomial model on overdispersed counts. Promotion IRR 1.59 (p < 0.001). Log-price elastic. Near-shoring and product-copy terms insignificant. ANOVA on origin: p = 0.091.

Margin trap: A ~59% unit lift still loses ~20% gross profit under a 30% discount on 60% margin goods, before apparel return drag. The volume number does not survive contact with unit economics.

Engineering Focus

⚑

Systems & Edge Runtimes

Building lean, low-latency applications that minimize unnecessary network hops. Stateful WebSockets, Durable Objects, lock-free SQLite WAL storage, and clean architectural boundaries.

πŸ›‘οΈ

Vulnerability Discovery

Specialized focus on web application business logic flaws, parser normalization discrepancies, and state machine violations where automated scanners fail.

πŸ“Š

Empirical Data Systems

Separating actual signal from noise in chaotic distributions. Event clustering, predictive market microstructure, risk constraints, and statistical retail analysis.

AppSec Practice

Security Research & Business Logic Flaws

Most severe modern web vulnerabilities aren't syntax typosβ€”they are business logic flaws: assumptions about user sequence, state validation lapses, and discrepancies between what a reverse proxy accepts versus what a backend parser processes.

I conduct independent research under responsible disclosure programs, designing custom tooling like Input Mutator to test normalization boundaries.
